The error does not happen if I remove LC_ALL=C and did $ apt-get install language-pack-en-base $ dpkg-reconfigure locales
I nevertheless think that the bug should be fixed, since LC_ALL=C is the standard way to get english messages on an non-english system. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1175895 Title: do-release-upgrade fails: TypeError: decode() argument 1 must be string, not None To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1175895/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
