(I'm not sure if I'm on the right track and whether the information below is everything. I'm still researching and trying to figure out what to do. There's no backup available. I'm looking for any possible hints/logs/commands/etc.)
Debian Wheezy 7.x 32-bit (I know I should upgrade, but bear with me)
I'm in a bit of a pickle. I tried to upgrade a chroot'ed environment and it seems I broke dpkg in the process.
I don't know if the cause of the problems is that apt-get isn't able to handle a qmail upgrade or if it's something else (it seems snmpd also didn't "finish" during the last round).
I think the error I'm trying to address is:
E: Sub-process /usr/bin/dpkg returned an error code (1)
I might have some of the information from the console when this first broke, but it seems I can reproduce as per below.
It seems I have a very old version of qmail, and upgrading to the one in my apt mirror is too much of a change. I've googled, and have not been able to find anything between 1.03-38 and 1.06-5 yet.
