Ubuntu 16.04LTS -> 18.04LTS upgrade failure

Yes it was a long in the tooth install. But it finally got a release upgrade. Since then I haven't been able to get apt to install anything much looking for dosemu but has no targets, and update spews errors about InRelease not containing bionic.

W: Skipping acquire of configured file 'bionic/cnf/Commands-amd64' as repository 'http://archive.ubuntu.com/ubuntu focal InRelease' doesn't have the component '

The google-fu gives all sorts of strange answers, but nothing I can find fixes this issue.

  • Can you update your question to include the contents of /etc/apt/sources.list? You'll probably need to make some edits in there. –  Mar 01 '21 at 05:46
  • There should not be distribution 'focal' listed because you only upgraded to bionic. – jarno Mar 01 '21 at 06:39
  • Added sources.list – A.Adverse Mar 01 '21 at 07:50

    What does lsb_release -r tell? – jarno Mar 01 '21 at 09:03
  • lsb_release -r = 18.04 – A.Adverse Mar 01 '21 at 11:17
  • Did you try to upgrade to Focal as some point? I think you have to manually edit the file and possibly some files under /etc/apt/sources.list.d/ to not contain words focal or focal-*, but contain respective bionic and bionic-*, instead. (only one at a line) – jarno Mar 01 '21 at 12:17
  • no idea what Focal is... pretty sure whats in there are defaults, I'm beginning to understand the error better.. its focal missing from bionic, not bionic itself that's missing? – A.Adverse Mar 01 '21 at 20:49
  • focal is the codename for Ubuntu 20.04. Like bionic is the codename for 18.04 (and is given by lsb_release -cs) In 20.04 I have a word starting by focal in every deb line in /etc/apt/sources.list and no bionic there. Not all files in /etc/apt/sources.list.d/ might have one of those words, though. See man 5 sources.list for reference. – jarno Mar 02 '21 at 06:19
  • if you'd like to post your first question phrased as an answer, I'll give you the bickies. I better go back and put bionic in there, but removing focal got me over the speed hump. Thanks. – A.Adverse Mar 02 '21 at 09:38

You have to manually edit /etc/apt/sources.list and possibly some files under /etc/apt/sources.list.d/ to not contain words focal or focal-*, but contain respective bionic and bionic-*, instead. (Only one of them per line.)
