Can anyone please verify that the syntax in this answer is correct?

A: apt-get - select the oldest google-chrome file in sources.list.d

Make a DPkg::Post-Invoke command that runs after using apt/dpkg. Create the file /etc/apt/apt.conf.d/100post-invoke with the contents: # This is a list of shell commands to run after invoking dpkg/apt-get # DPkg::Post-Invoke { "[[ rm -f /etc/apt/sources.list.d/google-chrome.list"; }; Now, after ...

I don't have extensive experience with apt post-invoke scripts/commands, but my initial testing (and other sources I've seen) tells me this answer should do the the OP is after.

Please comment or suggest if I'm missing something.

Hi guys, I'm having trouble understanding why there is GRUB_DEFAULT=saved and GRUB_SAVEDEFAULT=true, here: gnu.org/software/grub/manual/grub/html_node/… The documentation is kinda confusing, it says GRUB_DEFAULT=saved can be useful just by itself, but how I understand it is that without GRUB_SAVEDEFAULT=true it actually won't save it, so how can these two be separate?

Artur Meinild

It's actually explained pretty well..

GRUB_DEFAULT

If you set this to ‘saved’, then the default menu entry will be that saved by ‘GRUB_SAVEDEFAULT’ or grub-set-default.

Notice or grub-set-default

GRUB_SAVEDEFAULT

If this option is set to ‘true’, then, when an entry is selected, save it as a new default entry for use by future runs of GRUB. This is only useful if ‘GRUB_DEFAULT=saved’; it is a separate option because ‘GRUB_DEFAULT=saved’ is useful without this option, in conjunction with grub-set-default.

GRUB_DEFAULT=saved can be used by itself

The "saved" value will be either 1) The entry chosen by the command grub-set-default or 2) The last entry selected in GRUB only if the option GRUB_SAVEDEFAULT=true is set

Hakaishin

@ArturMeinild so if I use it by itself and then select an entry it won't save it for the next reboot?

Artur Meinild

If you use GRUB_DEFAULT=saved by itself, it will be the value stored in the default file

And it will not change, unless you specifically change it with grub-set-default

Hakaishin

isn't that like the default behaviour, to take the default file? why is that an option?

Artur Meinild

09:00

The GRUB_DEFAULT= is the first entry (0) by default

If you have more questions, please ask the Grub developers

Hakaishin

ah I see, interesting

Artur Meinild

The value saved is there so it can be updated dynamically

Hakaishin

So there are kind of 2 defaults, 1 is the default file and the list of kernels is also kind of a default

Artur Meinild

Either by your selection, or by invoking grub-set-default (could be se by scripting)

Hakaishin

Although I get it now, it seems a bit of a weird choice to have two places where a default can be stored

Artur Meinild

09:02

I believe you should think of it this way:

If you set GRUB_DEFAULT="value", then the default selection is completely static, and will never change, unless you change the config

If you set GRUB_DEFAULT=saved, then the default selection is "dynamic" - it may change with selection (GRUB_SAVEDEFAULT=true) or with scripting or any other way of invoking grub-set-default`

This is the best way I can explain it

Think of it as static or dynamic defaults

Hakaishin

Makes sense, thanks

Videonauth

10:46

yikes, whats up with the spam? this is for real terrible

vidarlo

This minor issue of a strike?

Videonauth

@vidarlo yeah maybe, but i dont know how many i flagged as spam last night , it was hilarious more or the less, flagged one came back to the page to be greeted with two more etc

vidarlo

Yep

But smokey is offline due to the strike, and a lot of users like me are participating and not flagging

so net result is that spam that required one real user vote previously now requires 5

Videonauth

11:01

yeah sad affair, im not to much into the matter so im not picking sides here, i falgged in the past 12 hours around 19 spam posts

Journeyman Geek On Strike

Might be 3

I vaguely recall they'd done that on (some? all?) sites

vidarlo

@JourneymanGeekOnStrike Really? CV is 3 on some sites

Journeyman Geek On Strike

vaguely ._.

vidarlo

I know it's lowered from 8 to 5. 3 is news to me.

But sure, wouldn't surprise me.

Videonauth

efery spam flag reduces the post by one negative vote, having 6 of them deltes the post

Journeyman Geek On Strike

11:12

the downvotes and obliteration are not related

Videonauth

true as many people simply downvote and not flag :)

Journeyman Geek On Strike

and practically a curator strike and smokey being down is the worst case scenario

We can self organise flagging (and frankly, mods seeing spam flags before community deletion also results in the user being deleted)

Videonauth

well i will flag as long i see them

Journeyman Geek On Strike

I'm on strike but I'll deal with whichever spammers I see later

Artur Meinild

Unfortunately, I'm also in the strike, so I don't flag, downvote or anything else.

The site must burn until SE get their sh*t together

Videonauth

11:19

good to know, im not picking sides is simple, i due to my psychological shortcommings not have the attention span anymore to read through hundrets of posts :)

Hakaishin

what are the demands from the mods?

Q: Moderation Strike: Stack Overflow, Inc. cannot consistently ignore, mistreat, and malign its volunteers

Introduction As of today, June 5th, 2023, a large number of moderators, curators, contributors, and users from around Stack Overflow and the Stack Exchange network are initiating a general moderation strike. This strike is in protest of recent and upcoming changes to policy and the platform that...

Under the heading: What the striking users want

vidarlo

@Videonauth That's perfectly fine; noone here is blaiming you for attempting to keep the site operating :)

Videonauth

@vidarlo well, my whole linux adventure started here 6 years ago :)

vidarlo

hehe, and you've come far :)

and I hope the strike is resolved soon, so we can make things right

Journeyman Geek On Strike

11:25

My flamethrower is cold and hungry.

:D

Artur Meinild

@JourneymanGeekOnStrike 🔥😁

Videonauth

build my first real good computer last year on my 50th bd

Journeyman Geek On Strike

What's the second PCI card?

vidarlo

@Videonauth Congrats:)

More graphic cards than I've had :D

Videonauth

@JourneymanGeekOnStrike USB hub for 8 USB 3 gen 1 and 4 USB c

Journeyman Geek On Strike

11:29

ahh

Videonauth

board is from 4 yeras ago chrismass from a friend but now i maxxed it out technically, 64 GB ram, and an i9-9900k

Artur Meinild

@Videonauth Looks dope! 😁

Videonauth

and yes this is outdated tech, but in face of the energy problems we have and the rising prices this was the most reasonable build

vidarlo

meh

my mediaplayer pc has an i5-650

it's 12 years

Videonauth

most love i have for the case :D

i wanted this one since 2014 when it first hit the market

vidarlo

11:31

:D

Journeyman Geek On Strike

@Videonauth lol

Videonauth

corsair carbide air series

Journeyman Geek On Strike

I have one of those

terdon on strike

@Videonauth This is a very good, and balanced, summary: jlericson.com/2023/05/31/mod_strike

Artur Meinild

So since we are showing off hardware... 😁

Journeyman Geek On Strike

11:32

and frankly its fine :D

Artur Meinild

Videonauth

i love the computer sitting here at 39°C on idle when room ambient is 30°

Artur Meinild

My homelab server rack

Journeyman Geek On Strike

nice lol

I need to figure out that sorta thing soon. I'm finally getting my new apartment after an almost 2 year delay from the original date

Artur Meinild

The entire rack with Firewall, 16 port Switch, Main server (Supermicro Atom) and a couple of Raspberry Pi's use 55 Watts in total

Videonauth

11:34

Artur Meinild

Pretty happy I went with a low-energy solution considering the prices last year. 😎

Videonauth

old case and setup beside the new one

Journeyman Geek On Strike

.... how old is that case 0_0

Artur Meinild

@JourneymanGeekOnStrike From the 90's it seems.. 😅😅

Or early 2000's 😎

Journeyman Geek On Strike

@ArturMeinild I've got ethernet prewired so while I'm not going for so many ports, planning on having the whole setup multigig capable

Videonauth

11:37

@JourneymanGeekOnStrike i got it in 2002 after it has served 5 years in my friends care

and the carbide air series is /was new last year

Journeyman Geek On Strike

Ah

Videonauth

it was housing a i5-8400 on the same board im using now

Artur Meinild

@Videonauth I remember the days of DYI computer in large towers like that.. 😅

Videonauth

oh i love it and im not done with marvin yet

next is a build in Pi 4 8gb driving the machines sensoring and so on

Journeyman Geek On Strike

most of my ~~farm~~ petting zoo's NUCs lol

Artur Meinild

11:40

Anyone who have installed at least one Plextor CD recorder, raise your hand! 😅

Journeyman Geek On Strike

I need to reorganise them at some point, but I'm planning on running my in house monitoring, home automation and stuff in proxmox

@ArturMeinild I think I've owned a few litheons and whoever creative bought from

Videonauth

@ArturMeinild i not have but i have this :D therocketplatform.com/ProductImage/…

Journeyman Geek On Strike

Yanno, if we're comparing wierd old gear...

I have an ancient SGI octane in a corner somewhere :D

Artur Meinild

@Videonauth Tape backup - OK I've never had that.. 😅

Videonauth

i got one of those drives and a full bag of tapes back a few years, still searching for a viable scis solution to run it tho

vidarlo

11:46

Had a tape robot at a point

12x50GB tapes I think

Videonauth

thats cool stuff yeah

still traing to find a way to upcycle this old stuff for a new use case

Journeyman Geek On Strike

>_>

I uh, generally throw linux on it

but saying that here feels like trying to sell snow to eskimos :D

Hakaishin

@ArturMeinild Interesting read. I mean SE has been all downhill since Monica. She was the first stone, but after her it was clear that this thing is the titanic, bound to sink, it's just a matter of time

Videonauth

@JourneymanGeekOnStrike is there any other viable os than linux? :P (no i not need an answer to that!)

Journeyman Geek On Strike

@Videonauth I've been joking about moving to haiku for years

@Hakaishin Eh no

It started doing downhill halfway through Joel taking over

I think the 'turning' point was the downsizing exercises

Artur Meinild

11:57

@JourneymanGeekOnStrike I've always found BeOS / Haiku fascinating

Journeyman Geek On Strike

@ArturMeinild Its frustratingly close to being usable

they ported epiphany recently but it apparently crashes on x64

Artur Meinild

I like its simplicity and design philosophy

Journeyman Geek On Strike

yup

Artur Meinild

I've never had any usecase for it, but I still really like it.

Journeyman Geek On Strike

frankly these days ...

all I need is a web browser, and a media player

Artur Meinild

12:01

@JourneymanGeekOnStrike You can come a really long way with that..

Journeyman Geek On Strike

Precisely

Videonauth

im happy that linux and gaming did come a long way the past few years

and im even dualbooting, 20.04.4 and 20.04.4 :D one is factory so to say a simple linux which is not set up much and always will work in safe mode, and one i usually use normally

vidarlo

12:55

So at least one person in here is actually using Ubuntu :D

Journeyman Geek On Strike

lol

I run it on 2 seperate boxen

Videonauth

@vidarlo started with it and despite the snap insanity im fine using it, although considering switching if even more apps will be snap exclusive so to say

vidarlo

13:14

yeah, that's what moved my last system away from it, onto Opensuse

Artur Meinild

13:27

@vidarlo hey Im using Ubuntu server 😅😎

vidarlo

hehe

impressive ;P

Artur Meinild

14:04

So now we're up to 3 people 😅

Hakaishin

We are all using Ubuntu desktop and server at work :)

Journeyman Geek On Strike

I also need to get a home assistant VM up at some point ._.

(not decided if I should use their full distro or run it over ubuntu LD)

vidarlo

HA runs very well in Docker

Journeyman Geek On Strike

@ArturMeinild that's not shocking on an ubuntu chatroom

@vidarlo I don't really like containers here since I might want to do some hardware passthrough

vidarlo

hehe

yes, there's that

I have a RPi with usb dongles at home, talking MQTT to a HA instance running in Finland

Journeyman Geek On Strike

14:09

Well the plan is to consolidate HA and a few other things to one VM host

Videonauth

@terdononstrike thank you and yes i see a problem with AI content and the tools used to indentify AI content, many stuff ive written over the years are being flagged by gptzero for example as highly likely being AI content, thus the reason why i not write anymore

terdon on strike

Oh yes, the detectors don't really work. Which is why no mod relied on them.

Videonauth

i see AI as a problem like the technical advancement over the past 30 years where legislation and rules where only made in retrospective as the tech evolved so fast, problem with ai is, those rules have to be in place already or it will get so out of hand that it throws us back

Artur Meinild

14:25

@JourneymanGeekOnStrike Well, it's kind of standing joke here that few people actually use Ubuntu.. 😬😎

Journeyman Geek On Strike

lol

Artur Meinild

But of course many do.. 😅

Journeyman Geek On Strike

I feel like most ubuntu users are less... snooty about it

I mean its less "Oh its better" or "Oh its 1% faster" or...

its "eh, its doing the thing in the corner"

Artur Meinild

Are you comparing to any other community in particular?? coughArchcough

Journeyman Geek On Strike

@ArturMeinild amusingly enough - sysadmins and Red Hat... I'm curious to see how that crowd goes, and gentoo and Arch folks too

But I LIKE the gentoo and arch folks

they got good documentation

Artur Meinild

14:28

@JourneymanGeekOnStrike The Arch wiki is actually totally awesome

Journeyman Geek On Strike

Yup

Artur Meinild

Hands down - I've taken quite a bit of config snippets from there

Journeyman Geek On Strike

and I'm in the philosphy of preferring to set up things from as close to scratch as possible over 'docker or nothing' installs

Artur Meinild

And of course it's caricature..

Journeyman Geek On Strike

lol

there's a few people who remind you every chance they get

Artur Meinild

14:29

But there are some Arch Youtubers, where you're definitely not in doubt what they're running 😅

Haha yes

The old joke: "How do you know people are running Arch?"

They WILL tell you!

Journeyman Geek On Strike

Like vegans :D

At the end of the day its a tool I know well

I mean, sure there's probably a better way, or a more elegant way but, its the hammer I have, and know well

terdon on strike

14:44

@ArturMeinild Do you know what distro I use?

Artur Meinild

@terdononstrike hmm no? 😎

Journeyman Geek On Strike

@terdononstrike I vaguely recall Gentoo

Artur Meinild

Gentoo.. I have actually zero knowledge about Gentoo

I know it exists - and that's about it. 😅

Journeyman Geek On Strike

I was actually thinking of moving one box (my router) to a RH-alike but now I'm probably not

(since I use firewalld for firewall management and nothing on it us ubuntu-specific)

Artur Meinild

@JourneymanGeekOnStrike Yeah RH is quite messy atm..

terdon on strike

14:57

@ArturMeinild Phew! I was afraid I'd acted like one of the fanbois you were (very reasonably) complaining about :) No, I use Arch.

Artur Meinild

At least until they figure out if Alma and Rocky can continue to be updated properly..

Journeyman Geek On Strike

@ArturMeinild its still a bit of a workaround

Artur Meinild

@terdononstrike Makes sense, since you're obviously a power-user - and I mean that in a good way

Journeyman Geek On Strike

and I do often do the whole 'install stuff and forget about it for years' thing so ...

long term stability is nice

Artur Meinild

And I do get the entire AUR and latest software thing

Journeyman Geek On Strike

15:00

@ArturMeinild actually that's a thing

How bleeding edge/stable/boring do you want? :D

Artur Meinild

But since I'm more into running server, I prefer a more stable base - and I've known Debian for a long time

I think Ubuntu sits in a nice spot between Debian and some of the more bleeding edge distros

Journeyman Geek On Strike

ah yup

bit they also do a few NIH things

Artur Meinild

The release cadence is well known, the packages are OK updated, and it's pretty solid

I also don't agree with some of the snap stuff - but I can live with it for now..

terdon on strike

@ArturMeinild Actually, for me, the thing that really convinced me to stay with Arch after trying it was the absence of apt's dependency hell.

Artur Meinild

Hmm yeah ok

So you can't have dependency hell with Pacman?

terdon on strike

15:03

I also liked how much I learned while installing it and setting it up, but that's the hardcore geek in me. The packaging system is the first time I've seen something that actually does just work.

Journeyman Geek On Strike

@terdononstrike ah that's a thing

terdon on strike

@ArturMeinild I don't think so. At least, I haven't seen it once in the ~6 years (I think) that I've been using Arch.

Journeyman Geek On Strike

I want to get running fast, and then do stuff

IIRC arch has no official installer?

terdon on strike

Then you don't want Arch, no question.

@JourneymanGeekOnStrike Not really, no. You boot to a command line and follow the Arch guide to the letter.

Journeyman Geek On Strike

Ya

Have a short attention span

I uh

terdon on strike

15:04

It is not for the non-expert user, and not for any user who doesn't actually want to tinker.

I installed it when I was between jobs and had time to tinker :)

Journeyman Geek On Strike

@terdononstrike I like tinkering, and am decent, but also SQUIRREL

Artur Meinild

@terdononstrike That's good.. I've been running a couple of Ubuntu servers for over 3 years now, and I've never had any dependency problems either

But I'm also mostly sticking to stock packages

I believe dependency problems mostly arise when people don't know what they're doing, to put it bluntly

terdon on strike

Oh. I used to get apt issues all the time when I was using Debian-based distros.

Artur Meinild

And yes, that's a real problem of course

terdon on strike

It is entirely possible that I didn't know what I was doing, but I think my issues were more caused by things like requiring specific versions of tools or needing to compile some things that were not in repos etc.

Artur Meinild

15:08

@terdononstrike Yes - I can image that can cause some trouble..

I think you're right that apt isn't really geared for needing specific versions.

With apt you pretty much have to stick with the version in the repos - or install in some other way

Else you will get issues

terdon on strike

I also dislike the need to reinstall all the time (I could never get the dist-upgrade to work cleanly). On the other hand, I do miss some of the ease of use that the Debian world has.

It's always a trade off.

Artur Meinild

True.. 😎

I'm just used to Debian/Ubuntu, and I know apt well

terdon on strike

I've been thinking that my next (work) computer will be a mac though. Their hardware has gotten so bloody good, and they are a proper *nix system these days and you can install GNU tools so it might be worth it.

@ArturMeinild Oh, I used Debian based systems (Ubuntu, LMDE, Mint) for most of a decade.

Oh. No, considerably more than a decade, actually :)

At various times, I've been a user of Mandrake, SuSe, open SuSe, Red Hat, Fedora, Arch, Ubuntu, LMDE and Mint.

Artur Meinild

Yeah well I still think there has to be some heavy arguments for me to switch, as Ubuntu pretty much does what it needs to do for me

Journeyman Geek On Strike

I think I used mandriva, SUSE (10.1 with the broken package manager) RHEL/Centos (old job)

terdon on strike

15:12

@ArturMeinild In that case you should not switch!

Journeyman Geek On Strike

oh and HP-UX ._.

At the end of the day, its a perfectly good hammer :D

Artur Meinild

@terdononstrike Yeah the new Apple platform is blazing

I've never been that much into Apple either, think it'll be too big of a switch for me..

Journeyman Geek On Strike

If/when I retire my SP, I kinda want a framework :D

Or some wierd chinese machine ._.

@terdononstrike after a few, incidents, most of my builds are documented

terdon on strike

@ArturMeinild I might end up installing Linux on it.

Journeyman Geek On Strike

I really need to get some sort of config management up :D

terdon on strike

15:18

@JourneymanGeekOnStrike like this?

$ wc -l README.install
1893 README.install

Videonauth

@terdononstrike youre only a real linux user if you ever attempted an install on a dead badger :P

Journeyman Geek On Strike

@terdononstrike something along those lines

terdon on strike

@Videonauth Hey, it was alive when I started installing, your honor, I swear!

Videonauth

:D

Artur Meinild

16:13

@terdononstrike 😅

andrew.46 - On Strike

23:41

@Videonauth Looks nice :). I see mechanical HDDs and in an unusual position?

Journeyman Geek On Strike

23:58

@andrew.46-OnStrike Its quite practical

and honestly, still can't beat running spinning rust for bulk storage

(as someone whose primary system is entirely nvme flash based even!)
