[Bug 349469] Re: debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable

[Steve Langasek]

dpkg-reconfigure in fact does not invoke either apt or dpkg, so it's
normal that it doesn't take the locks.  I think it would be very strange
if either dpkg-reconfigure or tasksel accounted for the very many
reports of this bug however, as both interfaces are very low-level and I
would expect at least one of the bug submitters before now to have
mentioned they were running such a command if so.

I think the duplicate bug count/frequency is a sign that something is
going wrong and invoking debconf on behalf of the user *without* being
initiated from the commandline.

I think I also have to say that, if this really comes down to dpkg-
reconfigure or tasksel, rather than having these tools claim apt or dpkg
locks directly, we should probably regard the failure as user error and
arrange to suppress the error reporting.
