Ubuntu: Ubuntu 16.10 Yakketty won't update. Can I fix it, or should I get 16.04, or 17.10? [duplicate]



Question:

This question already has an answer here:

So I had a beautiful system running real nice up until I wanted to set up an old webcam last night. I did sudo apt-get update and got this:

Fetched 1,475 B in 3min 25s (7 B/s)  Reading package lists... Done  W: The repository 'http://security.ubuntu.com/ubuntu yakkety-security Release' does not have a Release file.

N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.  

And sudo apt-get install for anything yields

E: Package 'program' has no installation candidate  

I suspect that I'm having this issue because I'm using Ubuntu 16.10. If not, I'd like to know how to fix it, because I really like my system the way it is. Otherwise, I'd consider installing 16.04 or 17.10, but I'd also like to know which one is better, and if there is a way to install without losing all my programs and stuff. Some of them were pretty frustrating to install, and I really need them.

Thanks!


Solution:1

your problem is, as @Organic Marble said, that yakkety (16.10) is an "end-of-life" release.
For your problem to be fixed, you need to upgrade to another "end-of-life" release, which is zesty (17.04). And then, you have to upgrade from the latter to artful (17.10).

My answer is inspired by that reference. In which, @kap gives us the way to do, in a quick way, due to the fact that his question has been marked as duplicate. There, I also want to thank @Sidepipe - read his answer and comment -.

I tested it twice in a virtual machine - with virtualbox -, and it worked.
I, then, applied it with my main machine, and it has also been successful. I have to say that, this way out won't fix your "broken ppa". You'll have to find the right ppa for the artful release.

I won't explain everything. I'm sure you'll find answers by yourself, on StackExchange or elsewhere on the web.

Everything has to be done as root or via sudo.
To check your release:$ lsb_release -a or $ cat /etc/os-release

There we go, we have to parts.

I) Upgrade from "end-of-life" yakkety (16.10) to "end-of-life" zesty (17.04)

  1. Fix /etc/apt/sources.list.d
    • # update-manager - uncheck every ppa
  2. Download zesty.tar.gz
  3. Verify package authenticity - gpg files at same url
  4. Extract archive - and modify the following files
    • # vi ./DistUgradeController.py"
      • Change every "archive.ubuntu.com" ==> "old-releases.ubuntu.com"
      • Change every "security.ubuntu.com" ==> "old-releases.ubuntu.com"
    • # vi ./mirrors.cfg
      • Append "ubuntu/" to every "old-releases.ubuntu.com/"
  5. /etc/apt/sources.list
    • Change every "fr.archive.ubuntu.com" ==> "old-releases.ubuntu.com"
    • Change every "security.ubuntu.com" ==> "old-releases.ubuntu.com"
  6. # apt-get update
  7. # apt-get upgrade
  8. # apt-get dist-upgrade
  9. # ./zesty --mode=server --frontend=DistUpgradeViewText
  10. # reboot
  11. # apt-get update - troubles, see next step -
  12. Delete duplicate(s) in /etc/apt/sources.list
  13. # apt-get update
  14. # apt-get upgrade
  15. # apt-get dist-upgrade
  16. # apt-get autoremove
  17. # apt-get autoclean
  18. # reboot

II) Upgrade from "end-of-life" zesty (17.04) to artful (17.10)

  1. # do-release-upgrade
  2. # reboot
  3. # apt-get update
  4. # apt-get upgrade
  5. # apt-get dist-upgrade
  6. # apt-get autoremove
  7. # apt-get autoclean
  8. # reboot


Solution:2

Your suspicion is correct! 16.10 went end-of-life last summer and is no longer supported.

You may still be able to upgrade to 17.10 (17.04 is also end-of-life), but I am not sure about that. The upgrade path(s) do not work forever.

18.04 comes out in a couple of months, and will be a Long Term Support release.
