I received the notice that there's an update for my desktop install, but I'm unable to do so. There's no real error messages that I can see. I've run sudo apt autoremove, sudo apt upgrade, and sudo apt install, and it gives 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. This is my screen when I run do-release-upgrade:

What could be the problem here?

  • I'm comparing the log from my (successful) upgrade; it looks exactly like yours until the line running Quirks.bionicPostInitialUpdate. My next line is MetaPkgs lubuntu-core lubuntu-desktop. This log is not informative! – Organic Marble Aug 21 '18 at 0:52
  • Um, since you were careful to include it in some of the commands in your question, but not this one, you did do sudo do-release-upgrade, right? – Organic Marble Aug 21 '18 at 0:55

    Yes, the two logs are from that. I've done it both with and without sudo, and it gives the exact same output. – aynber Aug 21 '18 at 1:41
  • Did you run sudo apt update before sudo do-release-upgrade? If so can you list all your ppa's with command found in this Q&A: askubuntu.com/questions/148932/… – WinEunuuchs2Unix Sep 1 '18 at 18:36
  • Did you try using sudo update-manager or do you not have a desktop? – pbhj Sep 3 '18 at 11:13

try:

sudo apt-get install lsb-core

and then upgrade

Sometimes this package is missing or corrupted and the installer has hard time figuring out which version is currently running, There are lots of complains about that if you google it. The same might happen in Debian.

  • Package lsb-core is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source. E: Package 'lsb-core' has no installation candidate – aynber Dec 3 '18 at 13:56

Ubuntu has stopped supporting 32bit desktop systems as of 17.10. The latest version of 32bit is 16.04.5, per https://www.ubuntu.com/download/alternative-downloads .
