the ubuntustudio menu relies on the DE actually following the open desktop standards. Gnome never really has completely and has now moved away from menus all together, only supporting menus with separately developed "plugins". It appears mate has changed their menu farther away from the open desktop standard so the ubuntustudio menu add-on no longer works. You can check /etc/xdg/menus/applications-merged/ to make sure the file studio.menu exists. If so ubuntustudio-menu is correctly installed and the bug is with the DE.
If the problem is with the DE, there should be a file in /etc/xdg/menus/ with a .menu extension. (gnome-applications.menu for example) if there is such a menu there the line to look for is: DefaultMergeDirs/ (with less than and greater than symbols around it) and the ubuntustudio menu should work. (it will work better if that line is almost the last line before the last /menu line but many DEs get this wrong and are not willing to fix this bug) However if there is no .menu file there, then Mate has decided they do not care about the open desktop standard and there is little ubuntustudio can do. This would be a Mate bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881446 Title: ubuntustudio-menu disappeared from mate desktop on upgrade to 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntustudio-menu/+bug/1881446/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
