Ok I tested it on pl locale. Looks like in newer version it looks better, because I got
DEBUG The package 'update-manager-kde' is marked for removal but it's in the removal blacklist line in main.log (which previoulsy was not there), but unfortunetlly my proposed fix for DistUpgradeCache was invalid since error was still shown in apt.log : UnicodeEncodeError: 'ascii' codec can't encode character u'\u0119' in position 51: ordinal not in range(128) Logged from file DistUpgradeCache.py, line 661 (\u0119 i ę character which probably appeared in polish version of blacklist line: Dist-upgrade failed: 'Pakiet "update-manager-kde" jest oznaczony do usunięcia, lecz znajduje się na liście pakietów, których nie należy usuwać.' I do not know why it try to encode this line when it shown english version in main.log) I attach patch that fixes apt.log issue for me. ** Patch added: "patchDistUpgradeCache.patch" https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1310053/+attachment/4103880/+files/patchDistUpgradeCache.patch ** Tags removed: verification-needed ** Tags added: verification-failed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310053 Title: 13.10 to 14.04 upgrade: UnicodeEncodeError: 'ascii' codec can't encode character u'\xab' in position 13: ordinal not in range(128) Logged from file DistUpgradeCache.py, line 661 in apt.log To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1310053/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
