Package: python-apt
Version: 2:0.9.1
Severity: normal
Dear Maintainer,
I noticed that unattended-upgrade seem to fail randomly with string to
float conversion exception. I made some modifications to
unattended-upgrade to print the exception stack trace which points
python-apt status update parsing code.
Exception happened during upgrade.
Traceback (most recent call last):
File "/usr/bin/unattended-upgrade", line 382, in upgrade_in_minimal_steps

ValueError: could not convert string to float: amd64
Too bad the didn't reproduce any more when I modified python-apt to print
complete status line to stderr. But looking the status line made me
suspect that problem is caused by other side writing multilib selector
after package name randomly.
pmstatus:evolution-data-server-dev:40:Unpacking evolution-data-server-dev
I still have no idea what is writing to the stream from the forked process.
That information is hidden somewhere that I didn't quickly at least
figure out.
Possible fix in python-apt would be checking for the incorrect data and
reading all information after package name from one position more
towards right. But I'm not at all sure if that is correct fix so I'm not
even making that patch yet.
