strange upgrade bugs with "cannot access archive: No such file or directory"

[Reinhard Tartler]

hi folks,

While going through my bugmail I've noticed a number of bugs with the
same pattern that are assigned to various packages by bug triagers. All
Terminal logs look like this:

dpkg: error processing /var/cache/apt/archives/libmp3lame0_3.98.2+debian-0ubuntu1_amd64.deb (--unpack):
 cannot access archive: No such file or directory

With googling it seems that the following bugs follow that pattern.

https://bugs.edge.launchpad.net/ubuntu/+source/lame/+bug/446801
https://bugs.edge.launchpad.net/ubuntu/+source/cabextract/+bug/471901
https://bugs.edge.launchpad.net/ubuntu/+source/suitesparse/+bug/307078
https://bugs.edge.launchpad.net/ubuntu/+source/xvidcore/+bug/446807

I'm a big puzzled how these failures can happen. Did the file somehow
got deleted during the install process? I cannot imagine that some user
is calling an 'apt-get clean' deliberatly simultanous to running an
dist-upgrade, so I suspect something else is doing this.

Moreover, perhaps bugsquad has some infrastructure to batch-process this
kind of bugs?
