    Does this answer your question? How to install software or upgrade from an old unsupported release?. FYI: sudo apt-get update only updates the list of available software. It doesn't actually update any packages, much less upgrade to the next release. You shouldn't wait until after a release goes EOL to upgrade. If you don't want to have to upgrade your release every 6 months, I suggest staying with an LTS release. – Nmath Sep 28 '20 at 04:51
  • Is your system fully-upgraded? Refer https://help.ubuntu.com/community/EOLUpgrades as after a release goes EOL, it's repositories are moved (which can occur quickly, mirrors can drop an EOL release). This change is manual as it's expected users will release-upgrade prior to the EOL occurring (notice was given if you were watching). Refer the release notes for 20.04 (https://wiki.ubuntu.com/FocalFossa/ReleaseNotes) in the Upgrading from Ubuntu 18.04 LTS or 19.10 section for upgrade instructions. They were intended to be used before 19.10 reached EOL though. – guiverc Sep 28 '20 at 05:20

Yes, Ubuntu 19.10 is not supported anymore. You could change the repos in /etc/apt/sources.list from eoan to focal but that might be risky if your system crashes halfway. Or you could follow the guide at How to install software or upgrade from an old unsupported release?. The guide might be outdated. I did the first method and it worked fine.

  • That's treating Ubuntu like it's Debian but it's not. Maybe as a last-option, but it wouldn't be my first. The release notes for Ubuntu 20.04 LTS (https://wiki.ubuntu.com/FocalFossa/ReleaseNotes) have a fully tested and supported upgrade path/tool which is what I'd try first. Yes if repositories have moved, you'll have to follow the clues from your used link, or https://help.ubuntu.com/community/EOLUpgrades first .. but I'd not treat Ubuntu like it's Debian unless it's the last trick in the toolbox (it can lead to issues esp. with python) Upgrade via re-install is easy for desktops. – guiverc Sep 28 '20 at 05:07

  • sudo sed -i -re 's/([a-z]{2}.)?archive.ubuntu.com|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list

    sudo apt-get update && sudo apt-get dist-upgrade

  • @jakeMonk the eoan repositories haven't yet moved to old-releases so it doesn't yet need to be done. The official pages don't have a specific date when that occurs, except they state after the release reaches EOL (not how long after). As well mirrors & 3rd parties can drop support anytime after the release reaches EOL. – guiverc Sep 28 '20 at 05:32
