Conversely Gimp runs always in English and it's impossible to manually set another language: if you click Edit -> Preferences -> Interface the Language section offers only English (en_US) aside from System Language. In a terminal, typing LANG=it gimp (replacing it by ru, ja, ...) don't switch gimp to the wanted language To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gimp/+bug/1875829/+subscriptions -- Mailing list: https://launchpad.net/~ubuntustudio-bugs Post to : ubuntustudio-bugs@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntustudio-bugs More help : https://help.launchpad.net/ListHelp
