E: Internal Error, Could not perform immediate configuration (2) on mountall

Huh? What happened here? I mean, I still had this mountall bug around, so it wouldn't surprise me if apt-get runs some hooks on mountall to make sure we're actually up & running. Let's "fix" mount for now:

# mountall 
swapon: /dev/mapper/swap: swapon failed: Device or resource busy
mountall: swapon /dev/mapper/swap [15521] terminated with status 255
mountall: Problem activating swap: /dev/mapper/swap

# grep swap /etc/fstab 
## /dev/mapper/swap swap       swap    pri=1        0       0

# mountall 

Now mountall returns properly, but apt-get dist-upgrade would still present the same error. Manually installing the package in question helped:

# dpkg --force-all -i /var/cache/apt/archives/mountall_2.10_amd64.deb
# apt-get -f install
# apt-get -V dist-upgrade
