Background - I had been using Ubunto 18.04 LTS with a gimp with several python plugins that I use a lot - a contact sheet generator, and a path distance pixel counter in particular. The EOL of Ubuntu 18.04 in April 2023 prompted me to consider upgrade routes, and having tried a live version of 22.04 decided to *upgrade* the existing installation to Ubuntu 20.04 LTS. This resulted in the previous gimp being replaced with 2.10.18, and as I soon found, as have so many others, that the python scripts no longer functioned - and were not even shown on the menus. Lots of things tried; even rewriting the python scripts from 2 to 3 (using 2to3). The frequently suggested gimp-python2 appimage failed - apparently compiled on Ubunto 22.04, so it wouldn't work on my earlier 20.04. Various pythons were tried, together with various tricks to try and get gimp to use them. All failed. This page then came up in a search. I found that I already had the latest python-cairo, and that the two debs given in post #3 were available. Downloaded and built with dpkg. Success! Thanks again. This solution needs greater exposure, and longterm preservation of those debs ... -- You received this bug notification because you are a member of Edubuntu Bugsquad, which is subscribed to gimp in Ubuntu. https://bugs.launchpad.net/bugs/1881684 Title: GIMP Python Plugins Won't Run in Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gimp/+bug/1881684/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~edubuntu-bugs Post to : edubuntu-bugs@lists.launchpad.net Unsubscribe : https://launchpad.net/~edubuntu-bugs More help : https://help.launchpad.net/ListHelp
