Yes, this happens when there are non-ascii character in one of the apt sources files.
…which must be very common because the disabled sources comment added by the release upgrade process is localized ! For example in French, the following was added to all my sources.list.d/*.list.distUpgrade during former upgrades : désactivé pour la mise à niveau vers raring désactivé pour la mise à niveau vers saucy (which translates to something like « disable for raring uprgade disabled for saucy upgrade ») This gives us a clue that this bug is a regression from the Trusty cycle. The raring -> saucy upgrade did work eventhough there were already non-ascii characters in sources files. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1278280 Title: ubuntu-release-upgrader crashes with DistUpgrade/sourceslist.py", line 416, in save : UnicodeEncodeError: 'ascii' codec can't encode characters in position 97-114: ordinal not in range(128) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1278280/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
