This also happened to me, during upgrading to Gutsy: somehow my locale de_DE.utf8 got lost and I had to run "locale-gen" to make them available again. The broken locale setup seems to be the cause for this crash in apt-listchanges.
I have reported it upstream at Debian and will update this bug, when I get the bug number. ** Changed in: apt-listchanges (Ubuntu) Status: New => Confirmed -- [apport] apt-listchanges crashed with Error in setlocale() https://bugs.launchpad.net/bugs/91583 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
