PPA repository is preventing Ubuntu upgrade from 19.04 to 19.10
by kkoistinen from LinuxQuestions.org on (#4SWMA)
Dear readers,
I have problem upgrading Linux Ubuntu 19.04 to 19.10. Apparently there is a repository that contains erroneous information but I don't know how to remove it. Error message is as follows
"Unable to download updates:
failed to refresh cache: E: The repository 'http://ppa.launchpad.net/mystic-mirage/komodo-edit/ubuntu disco Release' does not have a Release file.
And after some trying new version requires that all the programs are installed. What I should do with this problem? Inserting command
ppa-purge gives error message
E: The repository 'http://ppa.launchpad.net/mystic-mirage/komodo-edit/ubuntu disco Release' does not have a Release file.
Warning: apt-get update failed for some reason
I am using instructions in https://linuxconfig.org/how-to-upgra...10-eoan-ermine and eventually I get following output:
sudo do-release-upgrade
Checking for a new Ubuntu release
No new release found.
Yours
Kimmo
