The apt command will throw the discussed error about not overwriting the file, but it ensures that our dependencies are installed and the deb package is downloaded into the cache folder.

sudo apt install openjdk-9-jdk end in an error

Yes, that's okay. Ignore it and continue. The next two should fix that.

sudo dpkg --configure -a throws me an error about the openjdk source package

Post it, please?

but at the end

ok sec

Looks good. What was the error from dpkg configure?

heres the error message

You installed the openjdk-9-jdk-source package as well, which depends on the -jdk package that failed to install yet. That's why.

But if there were no other errors, my approach seems successful.

yeah i did sudo apt-get install openjdk-9*

it seems so

You know if there's any kind of self-test for the jdk?

so you can now answer your own question :)

Just to make sure I did not screw anything up without noticing...

only if you build from source then you could run make check

Nope. :P

dont know if the test suite is included in the installer packages

Then I'll just hope it worked and state that until anybody objects. ;)

best is

just tried to do an apt-get remove openjdk-9* and one pakage is not properly installed or upgraded

btw while youre here i installed ubuntu on a stick, not a live usb , a complete instalation via debootstrap, the stick works and all but updating grub adds the laptops normal hdd into the list of boot options

any chanc you know how to prevent that?

dunno

Is anyone here good with Ubuntu?

only newbs here @HenryWhiteHatHacker but what do you want to know =) ?

I ran RM -RF /* sad :( by accident!

RM -RF /* why does it exist

Why

@Videonauth It's probably your -source package? That was not part of my instructions... It has to be installed and configured after the -jdk is working.

Wrote my answer now btw: askubuntu.com/a/769484/367990

erm @HenryWhiteHatHacker this sould not run normaly, at least not on ubuntu unless you added a certain flag to the command

@ByteCommander did you see my grub question here in chat ?

starred

@Videonauth With the star after the slash, it will run IIRC...

@Videonauth No, I haven't

Ah, that one a few minutes ago?

Just noticed it... Let me think.

yep

@Videonauth Is this helpful? askubuntu.com/q/443415/367990

let me see

ok moment ill try this, have to chroot myself in first

@ByteCommander askubuntu.com/a/769124/522934

So?

@ByteCommander yep this did it i guess

Cool. :)

Btw where was your gedit downgrading tool again?

just llok at the question made by me in my profile :)

@HenryWhiteHatHacker if you did run that the possibility is very high you have shot your system beyond repair, only thing i could think of repairing it would be a debootstrap

the scrit for it has ti run as sudo @ByteCommander

@Videonauth So your script removes the 3.18 gedit while @Serg's script preserves the new version and installs the old one in parallel?

Here we ho again. Is reading really that difficult?

@ByteCommander yes

and sergs scritp only covers gedit, not the plugins and mine covers every avaiable plugin on the market

@Videonauth Will yours leave any persistent changes to other parts of the system, i.e. the sources.list? Or is that only a temporary change?

only temo change

at the end the sources list will be copied back

and in case the script fails the sources list is in sources.list.orig

okay, then I'll run it now. If it works, expect a bounty :)

it worked on my machine like a charm, on my stick like a charm and on sergs machine

should run

just keep the script it creates for you named gupgrade.sh

this will allow you to revert it all

Oops. Is it bad if just a minute ago a new update popped in, right after I updated and rebooted and before I just started your script?

the script runs an update and dist-upgrade anyways at the start :)

shouldnt matter

paste.ubuntu.com/16242973

heres the script as paste

should be even a pleasure to read i tried to ake it as clear and as commented as possible

grr

bricked again and I'm not even sure why

I hope this is only a soft brick

sleep well

Good night @ParanoidPanda ! going horizontally myself :)

Huh. It was just the SD card

OK. Enough fooling around with bootloaders until next week

I've been trying to help with askubuntu.com/questions/768916/… -- how do I tell the OP to get on chat so we can debug this interactively?

simply copy the char url and put it into a link

hi

anyone here good at java?

pretty straightforward. The package doesn't exist. So either you don't have it installed or it's not in your java path.

Is Java not a very insecure programming language?

as insecure as the programmer using it

Okay

Your very smart!

Lion guy

i mean , you can have the best encryption libraries and all that but if you fail with their implementation your encryption is same as having it plain text

just as example

^ Well said

Oh lionguy I want to tell you something since yesterday.

lol lionguy ?

Videonauth = "LionGuy"

His gravatar

what is it ?

Hold on

@serg :p two people one question hehehe

problem is on my side it didnt even work in temrinal i have no line with .net in the list

at least not if i run traceroute with -m2

but neverthe less both answers will work

@Videonauth well, that's because you have different servers between your router and 8.8.8.8 , they have different domain name

naw i wont get further out than two hops :)

same here, 2 hops - router and an one server in between

and there is not a server with .net in the name

$ traceroute -m 2 8.8.8.8
traceroute to 8.8.8.8 (8.8.8.8), 2 hops max, 60 byte packets
 1  192.168.0.1 (192.168.0.1)  1.362 ms  2.578 ms  5.507 ms
 2  hlrn-dsl-gw02.hlrn.qwest.net (207.225.112.2)  42.188 ms  45.282 ms  49.185 ms

oh . . .-m 2 , max hops . . . duh

 -m max_ttl, --max-hops=max_ttl
              Specifies  the  maximum  number of hops (max time-to-live value)
              traceroute will probe. The default is 30.

yeah in fact this is how you trace the connection to your providers entry point

tr -d will als work

$ tr -d '()' <<< "(207.225.112.2)"
207.225.112.2

yep

this is why i already love linux, so many ways to skin the same cat

Dear redhat , i would love to read your website on mobile, if only you could remove that ugly sidebar out of my face

@Seth I'm still a bit frustrated with dconf vs gsettings thing . Aside from doing the "integrity checks" I cannot find any actual advantage and/or danger of using dconf over gsettings, as Jacob keeps pointing out. I'm considering posting a bounty of question on that. Should I do that ? Because his nagging , quite honestly , is starting to piss me off

whats this about ?

@Videonauth On Windows , there is windows registry . On Ubuntu there's dconf database. And there's two command line tools that can alter values in that registry - dconf and gsettings. Both do the same thing, except gsettings is supposed to provide "sanity checks" for data you put in. So far I have not seen any advantage of using one over the other , but i'm getting critiqued for preferring dconf

ah ok

Maybe I am overthinking it, but I slightly don't like when somebody nags at me without any actual evidence

well i cant say much about it im only 3.5 months into my linux expierience

and as long it does what i want i dont care about gsettings or dconf

these are fairly useful tools . . . You can alter behavior of the desktop in many ways

Eh , whatever . . . . I probably shouldn't bother . . .

do you know maybe if i run chroot in a script and have commands comming behind, will those commands then run in the chroot or still in the subshell the script is in ?

I . . . have no idea, because never studied chroot in depth, only used it on live usb recovery

mhmmmm well i try actually to make my last monster answer into a script

means installing ubuntu on a stick with debootstrap

or whereever else external HDD internal other partition etc

Dude ! 65 is e in ascii

I need some guidelines to get started on porting Ubuntu touch on new hardware.

basically it says learn to port cyanogenmod first @RishavAmbasta

@Mateo Thanks
