Question Ubuntu MATE turned into Trisquel under my nose, anything I can do?


Hi there! This my first here after lurking for a bit and eventually having a very interesting issue.

I'm fairly new to the whole Linux thing. I've used it in the past for the briefest of moments, but just within the past month or so I switched over from Windows 7 to Ubuntu MATE.
Immediately after I started downloading software, especially games. And of course it was all stuff that I trust, like DOSBox, OpenRCT2, SCUMMVM, a few games from my GOG library, gPodder, etc etc.

Now I think it may have happened when I was trying to download either RubyRipper or eDuke32 (the last two programs I've attempted to download), but somewhere in there I must have used a command or something that switched Ubuntu to Trisquel.
I only just learned that my system made the switch, because when I was following the steps needed to download eDuke32 on Ubuntu, it came up with errors; when I tried an alternate download method- which required me to check my Ubuntu version- it came up saying that I had Trisquel instead.

I first went to the Ubuntu IRC and asked about it, they said I'm SOL and that I shouldn't "mix repositories" or something along those lines (which I don't understand).

I'd like to know:
  • What "Mixing Repositories" means and why I shouldn't do it
  • If there's there anything I can do to switch back to Unbuntu without a complete reinstall
  • and (If there isn't) Would you reccommend that I do a complete reinstall of Ubuntu MATE or just stick with Trisquel

About repositories: https://help.ubuntu.com/community/Repositories/Ubuntu

"Mixing repositories" (commonly referred to as "repos") would mean having links to incompatible repos in your /etc/apt/sources.list file, say, some Triquel repos mixed in with the Ubuntu repos. In that case, a software update or package install could pull in incompatible packages, leading to serious issues.

What are the contents of your /etc/apt/sources.list file? You display them in a terminal with this command:

Code:
cat /etc/apt/sources.list

a complete reinstall of Ubuntu MATE or just stick with Trisquel
installing software from random websites is a bad habit.
If you like it, keep it. else re-install.

PPAs and how to use them.

"Mixing Repos" is using repo entries from say Trusty on Xenial. Bad joo joo.
Or packages meant for one OS but installed on another.

New users should stick to Software delivered by the installed OS, IMO.
"Software Center" in Ubuntu I believe.

PPAs incorrectly used, can have unforeseen complications, as you can see.
Debian calls it FrankenDebian.

Ubuntu:SoftwareManagement
Ubuntu:What are Repositories?

Thanks frank.

Thank you both for the help! Although Trisquel may be a good distro I think I'll reinstall Ubuntu when I get the chance, since AFAIK there's more programs compatible with that than most other distros.

You don't need to re-install, but you do need to avoid having repositories from two different distros. If they use different versions of a library, an update could leave you with a broken system.

Run the Synaptic package manager. First find what you got from Trisquel and un-install it. You can look for it somewhere else later. Then choose the option in that program to manage repositories, and remove the entry for Trisquel.

It might be a good idea to make sure that your distro is not listed as Trisquel. Have a look in
/etc/issue
/etc/lsb-release
One or the other should exist and if it says Trisquel, change it.

Alright, I'll try that this weekend. Thanks!

By this do you mean that I should type in something else, or by "change it" do you mean "re-install it"? I checked this last night and both files said that I was using Trisquel ~v6.

I mean use the command "sudo gedit /etc/issue" (and similar for the other file name) to edit the files and replace "Trisquel ~v6" by "Ubuntu" and its version number. I'm not sure if those files are ever used by anything, or if they are just there so that anyone servicing the computer can see what's installed, but it's a probably good idea to have them saying the right thing.

Okay so I was just able to get around to doing this. The first thing listed that was installed by the Trisquel repository was the "base-files" package which looked awfully important. Here's what it's saying that I got from Trisquel:

base-files
compton
libconfig8
libruby1.8
ruby1.8

(So clearly I did that when I was trying to install RubyRipper. Whoops.)
Should I still try to uninstall the packages or am I truly SOL?

you are not SOL (i had to look that one up), but it would take some effort to undo.
not uninstalling the packages, but removing the wrong repositories in your sources lists, then updating/grading, hoping the packages get reverted to their original versions... i'm not 100% sure how the process would go, have you searched advice on that? your probably not the first, and probably someone made a nice blog article about how to attempt a fix?

I did try looking it up a while back but I didn't get any results. I'll do a backup and attempt this.

yes, search terms have to be revised constantly.

people should really write more about the art of using a search engine.

sooner or later that will become a vocation.

Oops! Those "base-files" are exactly the sort of thing you don't want replaced by the wrong distro. I think the other packages are safe. So, remove Trisquel from the repositories list and then re-install base-files so that you have the Ubuntu version.

Update: I started having many errors pop up when I booted the system, the system wouldn't update, and software wouldn't install in general. I backed everything up and reinstalled Ubuntu. Thank you to everyone who helped!
