How To: Fix apt update in Ubuntu 19.04

Ubuntu 19.04 Ubuntu 19.04

I needed to install something on one of my home automation servers running Ubuntu 19.04, and suddenly couldn’t - lots of errors with Disco updates and packages not found:

What’s the problem with updates in Ubuntu 19.04?

Turns out, 19.04 is too old now - so it’s been officially migrated from archive to old-releases repos in Ubuntu.

How To Fix The Missing Ubuntu 19.04 Updates

You need to edit the /etc/apt/sources.list file. Update the following lines:

/etc/apt/sources.list

to be:

deb http://old-releases.ubuntu.com/ubuntu disco main restricted
deb http://old-releases.ubuntu.com/ubuntu disco-updates main restricted
deb http://old-releases.ubuntu.com/ubuntu disco-security main restricted

Aftet this apt update will work just fine:

root@server:~ # apt-get update
Ign:1 http://nl.archive.ubuntu.com/ubuntu disco InRelease
Ign:2 http://security.ubuntu.com/ubuntu disco-security InRelease
Err:3 http://security.ubuntu.com/ubuntu disco-security Release
