I cannot update from 19.04 to 19.10 - 'no longer has a release file'

Question

I was attempting to upgrade to the latest LTS but, am required to update from 19.04 to 19.10 first. I have apparently missed the window to do so as when I attempt to do so with sudo apt-get update I get this result:

How can I update my existing release so that I can upgrade to a more current LTS? Thank you!

Hey @enjoypb - This is an issue that lots of users run into due to the earlier EOL date of Jan 23 2020 for Ubuntu 19.04

To fix your immediate issue though, I believe you can do this:

Add `old-releases.ubuntu.com` to the `/etc/apt/sources.list` file

Open up the apt sources file with:

sudo nano /etc/apt/sources.list

Replace all occurrences of archive.ubuntu.com with old-releases.ubuntu.com

For example:

before:

deb http://archive.ubuntu.com/ubuntu disco main universe multiverse restricted

after:

deb http://old-releases.ubuntu.com/ubuntu disco main universe multiverse restricted

Keep in mind that even Ubuntu 19.10 will go to end of life (EOL) in July 2020 https://wiki.ubuntu.com/Releases

Thank you for that response. I do not find any reference to archive in my source-list however. This is the verbatim copy. Note a few instances where I made modifications to suit my GIS-related installation. Do you know how I could include the lines you suggested? I’m trying to upgrade to 19.10 so I can further upgrade to the next level LTS. I have a bunch of GIS related elements and need to step through that carefully.

  OK I believe I have it fixed.
  I commented out the original deb sources above and added the line below them e.g.
  
  ##deb http://mirrors.digitalocean.com/ubuntu/ disco main restricted
  
  deb http://old-releases.ubuntu.com/ubuntu disco main restricted
  
  Thanks for your help!

This is the best answer to this question on the internet!

Everyone else give the same generic answer: “Your distro is out of date, please upgrade to 20.04”

I did personally upgraded, but I’m also temporarily running Ubuntu 19.04 on qemu(KVM) just so I can run some legacy software that doesn’t work anymore on 20.04.

Thank you!

I had the same issue but found I had to tweak the ’/etc/apt/sources.list’ file a bit further.

I was initially getting error messages like:

The repository 'http://gb.archive.ubuntu.com/ubuntu disco Release' no longer has a Release file.

I changed all references to archive.ubuntu.com with old-releases.ubuntu.com in '/etc/apt/sources.list' using :%s/archive.ubuntu.com/old-releases.ubuntu.com/

What I should have done though was:

:%s/gb.archive.ubuntu.com/old-releases.ubuntu.com/
