Bug#732617: Latest updates render Debian GNU/kfreebsd unusable

[Thomas Schweikle]

Package: grub, apt, dpkg
debian_version: jessie/sid

Hi!

Today I tried to upgrade Debian GNU/kfreebsd to the latest packages.
After running a while the upgrade process stopped with errors "E:
Sub-process /usr/bin/dpkg returned an error code (1)".
Starting "apt-get upgrade" again only lead to the same error.
Since the packages where downloaded I tried to update them manualy:
cd /var/cache/apt/archive
dpkg -i <pkg>

This time a lot of packages where unpacked, but again the very same
error "E: Sub-process /usr/bin/dpkg returned an error code (1)" after
apt-get trying to configure unpacked and installed packages.

doing "dpgk --configure -a" seemed to solve the error. A following
apt-get ran until the next configure part. Again the same error: "E:
Sub-process /usr/bin/dpkg returned an error code (1)".

At one point grub was upgraded. Some messages about passthru-drivers
not found or device da0s1 not being available hushed by. After an
additional "dpkg --configure -a" and further upgrades all seemed to be
OK.

"update-grub" did not give back any errors.

After rebooting a bunch of messages about /proc and others not being
found, missing files and such, the system booted to the prompt, but it
is impossible to login.

Looks like apt-get, dpkg and some helper scripts are badly broken now.
