Hi We were on Debian GNU/Linux 9 with Koha 19.11.00, our configured language was german (de-DE). Today we updated first to Debian GNU/Linux 10, then to Koha 21.05.01. At the end of the update it said: Upgrade to 21.05.01.003 done [19:19:38]: Koha 21.05.01 release Error: the selected language is already installed. Try --update if you want to re-install it. ERROR: an error was found when updating 'de-DE' translations. Please manually run 'koha-translate --update de-DE'. Run man koha-translate for more options. Now our language German (de-DE) is gone, instead only English (en) is there. The Koha system preferences "language" und "OPACLanguages" just show "English" but these checkboxes are not even checked. German is not there anymore. I tried to run "koha-translate" with various options but it didn't help: # koha-translate --list de-DE # koha-translate --update de-DE Error: the selected language is already installed. Try --update if you want to re-install it. # koha-translate --remove de-DE # koha-translate --list de-DE # koha-translate --install de-DE Error: the selected language is already installed. Try --update if you want to re-install it. When trying to use option "--dev" the program tries to access a non-existing directory called "koha-tmpl". # koha-translate --list de-DE --dev ndz ls: cannot access '/usr/share/koha/koha-tmpl/opac-tmpl/bootstrap/': No such file or directory How can we regain the German language?
