[Bug 950791] Re: <type 'exceptions.AttributeError'>: 'Transaction' object has no attribute 'pktrans'

[Tim Frost]

I applied updates as detected this morning NZ time using update-manager, then refreshed the lists and applied a second set of updates. aptdaemon crashed during post-processing after instalation of the second set of updates.
 /var/cache/apt/archives has two sets of files for aptdaemon:
tim at zaphod:~$ ls -l /var/cache/apt/archives/aptdaemon*
-rw-r--r-- 1 root root  15146 Mar  9 22:03 /var/cache/apt/archives/aptdaemon_0.43+bzr778-0ubuntu1_all.deb
-rw-r--r-- 1 root root  15130 Mar 15 02:04 /var/cache/apt/archives/aptdaemon_0.43+bzr784-0ubuntu1_all.deb
-rw-r--r-- 1 root root 162996 Mar  9 22:03 /var/cache/apt/archives/aptdaemon-data_0.43+bzr778-0ubuntu1_all.deb
-rw-r--r-- 1 root root 163060 Mar 15 02:04 /var/cache/apt/archives/aptdaemon-data_0.43+bzr784-0ubuntu1_all.deb
tim at zaphod:~$ 
Note that  timestamps are NZDT, 13 hours ahead of UTC.

After applying the second set of updates, update manager reported that a
restart was required, and the restart icon has apeared in the gnome
panel.  aptdaemon crashed at about the time when update-manager was
generating the reboot alert at the end of installation of the second set
of updates, but no crash occurred when I needed to reboot last (at least
2 days ago). This suggests that the bug was introduced between bzr778
and bzr784
