It looks like attach_mac_events() in hookutils.py needs updating too. And the package hooks for update-manager and ubuntu-release-upgrader need updating too.

[Brian Murray (brian-murray)]

Actually it is possible for dmesg to be collected provided you run apport in a GUI session or you run it as root. The actual problem is with there not being a pkagent running which is bug 1821415.
