Latest fix filling in 'N/A' for absent groups is working, apport-unpack is no longer throwing stacktrace when prcoessing the report. I still don't understand why primary groups are ignored, but the important thing is the reports are processable without errors now.
This might be a totally separate issue, but will it be possible to backport the 'N/A' fix to bionic? Reproduced by testing a user with a system group as their primary group (will have N/A in report), this is equivalent to the user being in no system groups (even though they are). Also a user which has an additional group which is a system group (will show that system group in report). # system group to test with sudo addgroup --system testgroup1 # create user with their primary group as the above system group (user doesn't have to be system user, just don't have to fill in gecos) sudo adduser --system --ingroup testgroup1 testuser1 # create user with additional group as system group, their primary group in this case is nogroup sudo adduser --system testuser2 sudo usermod -a -G testgroup1 testuser2 # run simple app as first user sudo -u testuser1 /usr/bin/sleep 60000 # kill and create crash report sudo pkill -SEGV -f '^/usr/bin/sleep 60000' report="/var/crash/_usr_bin_sleep.$(id -u testuser1).crash" # wait a bit while report is generated sleep 2 # check resulting crash report, should print UserGroups: N/A sudo grep -H 'UserGroups:' $report # try apport-unpack sudo apport-unpack $report /tmp/crash1 # reset and try with other user rm "$report" sudo -u testuser2 /usr/bin/sleep 60000 sudo pkill -SEGV -f '^/usr/bin/sleep 60000' report="/var/crash/_usr_bin_sleep.$(id -u testuser2).crash" sleep 2 # should print UserGroups: testgroup1 sudo grep -H 'UserGroups:' "$report" sudo apport-unpack $report /tmp/crash2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1427600 Title: apport-unpack: ValueError: ['UserGroups'] has no binary content To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1427600/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
