Hit this again just now. Apparently it is quite repeatable on my system at current. I was typing in a terminal when the GUI locked up. After the reboot I fired up Software Updater and it went through a little report cycle that brought me here.
I can see the following crash files /var/crash$ ll total 112620 drwxrwsrwt 2 root whoopsie 4096 Sep 9 13:52 ./ drwxr-xr-x 16 root root 4096 Jul 13 16:08 ../ -rw-rw---- 1 root whoopsie 0 Sep 9 13:51 .lock -rw-r----- 1 thomasthorne whoopsie 28933552 Sep 9 13:52 _usr_bin_compiz.1000.crash -rw-r----- 1 thomasthorne whoopsie 9080665 Sep 9 13:52 _usr_bin_pidgin.1000.crash -rw-rw-r-- 1 thomasthorne whoopsie 0 Sep 2 10:12 _usr_bin_pidgin.1000.upload -rw------- 1 whoopsie whoopsie 0 Sep 2 10:12 _usr_bin_pidgin.1000.uploaded -rw-r----- 1 thomasthorne whoopsie 4810182 Sep 9 13:52 _usr_bin_python2.7.1000.crash -rw-rw-r-- 1 thomasthorne whoopsie 0 Sep 7 16:50 _usr_bin_python2.7.1000.upload -rw------- 1 whoopsie whoopsie 0 Sep 7 16:50 _usr_bin_python2.7.1000.uploaded -rw-r----- 1 thomasthorne whoopsie 70072908 Sep 9 13:53 _usr_bin_skype.1000.crash -rw-rw-r-- 1 thomasthorne whoopsie 0 Sep 7 17:03 _usr_bin_skype.1000.upload -rw------- 1 whoopsie whoopsie 0 Sep 7 17:03 _usr_bin_skype.1000.uploaded -rw-r----- 1 thomasthorne whoopsie 2302186 Sep 9 13:51 _usr_lib_unity-settings-daemon_unity-settings-daemon.1000.crash -rw-rw-r-- 1 thomasthorne whoopsie 0 Sep 7 17:03 _usr_lib_unity-settings-daemon_unity-settings-daemon.1000.upload -rw------- 1 whoopsie whoopsie 0 Sep 7 17:03 _usr_lib_unity-settings-daemon_unity-settings-daemon.1000.uploaded -rw-r----- 1 root whoopsie 102800 Sep 8 13:40 _usr_sbin_aptd.0.crash -rw-r--r-- 1 root whoopsie 0 Sep 8 13:40 _usr_sbin_aptd.0.upload -rw------- 1 whoopsie whoopsie 0 Sep 8 13:40 _usr_sbin_aptd.0.uploaded Looks like a similar set to earlier in the week. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1022993 Title: aptd crashed with UnicodeDecodeError in _emit_acquire_item(): 'utf-8' codec can't decode bytes in position 0-1: invalid continuation byte To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/aptdaemon/+bug/1022993/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
