I also have this issue after an upgrade from 18.10. I don't see how this is NOT a bug. Simply working on a clean install doesn't make this a non-issue. Ubuntu is still expected to cleanly upgrade. I tried uninstalling and reinstalling Gimp and the Gimp libraries. It doesn't fix the issue.
The only good news I have is that the Snap Store version does work. I had to uninstall the apt release, and install the snap. -- 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/1820088 Title: GIMP doesn't start in disco dev To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gimp/+bug/1820088/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~edubuntu-bugs Post to : [email protected] Unsubscribe : https://launchpad.net/~edubuntu-bugs More help : https://help.launchpad.net/ListHelp
