While the do-release-upgrade was running, (in a separate window) I queried the current locale. It was:
$ locale locale: Cannot set LC_MESSAGES to default locale: No such file or directory locale: Cannot set LC_ALL to default locale: No such file or directory LANG=en_US.iso88592 LANGUAGE=en LC_CTYPE=hu_HU.iso88592 LC_NUMERIC=hu_HU.iso88592 LC_TIME=hu_HU.iso88592 LC_COLLATE=hu_HU.iso88592 LC_MONETARY=hu_HU.iso88592 LC_MESSAGES=en_US.iso88592 LC_PAPER=hu_HU.iso88592 LC_NAME=hu_HU.iso88592 LC_ADDRESS=hu_HU.iso88592 LC_TELEPHONE=hu_HU.iso88592 LC_MEASUREMENT=hu_HU.iso88592 LC_IDENTIFICATION=en_US.iso88592 LC_ALL= $ locale -a locale: Cannot set LC_MESSAGES to default locale: No such file or directory C C.UTF-8 en_AG en_AG.utf8 en_AU.utf8 en_BW.utf8 en_CA.utf8 en_DK.utf8 en_GB.utf8 en_HK.utf8 en_IE.utf8 en_IL en_IL.utf8 en_IN en_IN.utf8 en_NG en_NG.utf8 en_NZ.utf8 en_PH.utf8 en_SG.utf8 en_US.utf8 en_ZA.utf8 en_ZM en_ZM.utf8 en_ZW.utf8 hu_HU hu_HU.iso88592 hungarian POSIX So, do-release-upgrade (or the 'locales' package?) created many-many en_*.utf8 locales.. (-- which I do not needm never needed and never will need!) But "en_US.iso8852" was not created (and the previous generatum was dropped or lost). Despite that the (original) /etc/default/locale (and /var/lib/locales/supported.d/en etc.) do contained it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1802194 Title: do-release-upgrade gives many "locale: Cannot set LC_ALL to default locale: No such file or directory" messages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1802194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
