On a focal live cd, I tried to downgrade lightdm and accountsservice to their bionic versions and restart their services without rebooting, yet again the session was not translated. So I'm at a loss on which package was the one that caused the change in 19.10, maybe even glibc itself.
Nevertheless, I was able to reproduce a similar problem in a normal (non-live) focal installation, by just purging language-pack-el, or by just moving aside the directory /usr/share/locale-langpack/el and restarting accounts-daemon and lightdm. Without the language pack, my LANGUAGE is "en" and my session is untranslated. And if I launch d-feet and check /org/freedesktop/Accounts/User1000 => org.freedesktop.Accounts.User => property Language, it says "en". I think that is the problem, accountsservice should report that my language is either "el" or empty, but definitely not "en". Even if the langpack isn't there, LANG in /etc/default/locale is el_GR.UTF-8, and I don't have "en" defined anywhere in my system or my account; and MATE can show Greek even without a langpack. I think then LightDM will work fine without any changes. Does this approach sound OK? ** Changed in: accountsservice (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of DX Packages, which is subscribed to accountsservice in Ubuntu. Matching subscriptions: dx-packages https://bugs.launchpad.net/bugs/1861481 Title: language-options causes live CD sessions to be untranslated Status in accountsservice package in Ubuntu: Confirmed Bug description: Since Ubuntu 19.10, for all Ubuntu live CDs that use LightDM (e.g. MATE and Xubuntu), if a user selects a language in syslinux other than those with an included langpack, the session is then untranslated. For example, if one boots Ubuntu MATE 20.04 and selects Greek in syslinux, he ends up with LANGUAGE=en in the session. The chain of events is: LightDM has an Ubuntu-specific patch that makes it call /usr/share/language-tools/language-options instead of the upstream `locale -a`. `locale -a` does list el_GR as a supported locale because casper correctly updated the locales. But language-options doesn't list el_GR, so it fools LightDM into thinking that Greek aren't supported; while they're all there, since e.g. MATE doesn't rely on langpacks; mate-panel.mo and mate-calc.mo etc are all there. I believe the correct fix would be for language-options to list el_GR on live CDs (to merge the output of locale -a in its output). Thanks!
