Q: Changing ubunto machine password on temporarily basis

Yesterday, I was notified by the company manager to change my ubunto machine password and should keep it as strong as possible. So I changed it to @@Geo_016110240(for me this is strong and easy to remember). Now, the problem is most of the time I perform things as a sudo, which makes me tired to ...

@WinEunuuchs2Unix Read the comments before you vote. This reopen campaign is as fake as a three dollar bill.

Why do I even care if it gets reopened or not? I don't, it's just bullshit. This answer I do care about however because it links to a fake printer driver website that downloads garbage instead of the printer drivers from the official printer manufascturer's website. Under ordinary circumstances an answer like this would be consider SPAM. So vote your mind ↑ but help me to delete this spam.

The question about the printer driver grabbed 9 downvotes so far. These downvotes were cast in my opinion by frustrated Ask Ubuntu users who are sick of being spammed regularly by the same fake printer driver websites, and there's no way to get rid of the accepted answer because it got upvoted 5 times, but since today is apparently a reviewer election day I cast my vote to delete the spam.

@karel actually that's not fully correct. the link goes to a blog post but provides download links for Windows and Mac and who know, maybe they are scam links, but for Linux OS (which might be the only useful thing on that page) it links to https://developers.hp.com/hp-linux-imaging-and-printing. infact the wording is

> For Linux downloads, HP recommends another website. If you need to download Linux drivers.

however the answer you link to is lacking as it just says "go here and following the instructions" when really that should have been quoted on the page itself (along with the link) to avoid link rot, or better yet, following the links going to the end where the actual download link and information is and quoting that. and if that link is suspect

now if the link as nothing to do with the question or answer and doesn't help either , remove it because then it's very likely spam. but if the link is useful in some way and it's relevant, that's not spam but it borders on a link only answer and is susceptible to link rot

karel

06:05

I remember reading that which at the time I interpreted as a smokescreen to confuse visitors to the website that the website was legitimate which it isn't. It's a bogus website, one of a family of similar bogus websites, one for each major printer manufacturer. Ask Ubuntu gets spammed by several of these websites regularly. Serving warez masquerading as official printer drivers is not useful in some way and not relevant, it's called SPAM.

The only difference between this spam and other spam is that it's more popular spam, which as far as spam is concerned means that it is more destructive spam.

@karel Did you see Oli’s linkcheck.py? Makes it easy to eliminate links to certain domains from the site…

@Fabby well for AU data at least, still downloading on the unix.se data

@Videonauth That's the best that you could do because if I'm not mistaken we're stuck with the reputation on that answer where it is, but we're not stuck with the spam link.

wow another downvote for suggesting keeping the ubuntu system up to date .... -.-

i wonder what is up with the people

you SERIOUSLY should be more CAREFUL with sudo apt dist-upgrade it might screw up your system if you e.g. have installed third party packages, etc! You might want to change that post! (even so a dist-upgrade is NOT necessary to answer the question ) — Cutton Eye 2 hours ago

all i can say is i have a highly customized ubuntu with tons of thrid party packages and i never screwed my system up with doing an dist-upgrade ...

-.-

grml

I can tell you why it screws up your system, because you avoid updating it at all costs. I myself run ubuntu since nearly 3 years now and have it highly customized and an apt dist-upgrade never screwed my system up. And before you ask, yes as a hobby developer I have tons of customized packages and third party aps installed here. Therefor i think your downvote is unjustified. It is a valid answer, and i even mentioned it in the comment lines above the command that this can be skipped. — Videonauth 47 secs ago

Byte Commander

@Videonauth For apt, dist-upgrade is not necessary

Unlike apt-get upgrade, apt upgrade is allowed to install new packages by default

Videonauth

well i just managed to get apt-get out of my mind and with apt-get i used dist-upgrade

apt is just a warapper around apt-get as far i understood, but i can be wrong

Byte Commander

And the official apt equivalent for apt-get dist-upgrade is apt full-upgrade, although the other seems to work too

Videonauth

i guess it simply does the same

Byte Commander

I agree that you usually don't want an upgrade to remove packages though, so I'd not use full/dist-upgrade normally either

Videonauth

12:46

whats more bothering me is to get downvotes for a perfectly fine answer for just the reason i mention updating the system

dessert

@Videonauth have an upvote to compensate this madness :)

Videonauth

i always use it and never have run in a problem since 3 years

the problems mostly arise when you skip many updates and then try to install something

Byte Commander

I can't make a clear decision here, apt upgrade would be perfectly fine, but apt dist-upgrade is something I would not recommend, but not DV either... so /shrug

Videonauth

only time i had issues it was a faulty driver for the gpu

and once i shot my 17.10 main install because i wanted to install vlc 3 from bionic repo and forgot to pin the rest of the packages to artful :D

but this screwed me over badly hehehe

dessert

@Videonauth also: don't fret, you're not alone! ;)

Byte Commander

12:49

it's not about upgrading in general, it's about dist-upgrade being allowed to automatically remove packages to resolve conflicts, which can indeed screw your system up if your packaging system is in a somehow inconsistent state or a bad package gets updated to a version with new conflicts

Videonauth

true, can happen but to be honest did not happen to me in three years

and it only marks the packages for autoremoval

so you have to run apt autoremove

to finally uninstall them

Byte Commander

that is not true

Videonauth

it can replace newer packes with older ones yes

that was the reason of dist-upgrade while upgrade alone with apt-get only updates what it can

i will edit and make it upgrade and the haters gonna hate anyways

Byte Commander

apt-get upgrade only replaces older package versions with newer versions of the same package

Videonauth

right and dist-upgrade alows it to downgrade packages if neccesary

Byte Commander

12:53

but it did fail if the newer version had changed dependencies

i.e. it could not install or remove others

For example for a kernel update, you needed dist-upgrade

because e.g. the metapackage linux-image-generic updates to a newer version, which has the real kernel package (e.g. linux-image-generic-4.4.123) as new dependency, instead of the old

to upgrade that, it needed to install the new dependency package

now that is what apt upgrade does by default too

Videonauth

well here is what my computers do since i am on linux apt update && apt dist-upgrade && apt autoremove --purge && apt clean as cron job daily

since three years

without a hitch

Byte Commander

but apt full-upgrade or apt-get dist-upgrade can also automatically remove other packages, if the newer updated version of a package conflicts with something you have installed

Videonauth

and im on proposed branch

Byte Commander

this is rare, but can happen

/shrug

Videonauth

never happened to me :)

/shrug

Byte Commander

12:57

I always run apt update ; apt upgrade manually

Videonauth

this is my iron maiden cron job :P

always 5 minutes to midnight (i.e. 5 minutes before midnight)

but maybe im just lucky, or have set up my system properly so it does not kill stuff that easily, and even if, i would able to fix it myself
