/etc/bacula - you need confoiguration
/var/lib/bacula/bacula.sql - you need backup from database


Emergency Repair

DPKG , packages

http://www.thepowerbase.com/2012/04/how-to-fix-broken-packages-in-ubuntu-or-debian/

Copy Installation: 

dpkg --get-selections > mypackages.txt
sudo dpkg --set-selections < mypackages.txt
sudo apt-get dselect-upgrade

or

Repair broken: 

debsums -s -a 2> /tmp/broken.log
sed -n 's/^.*\(checksum mismatch\|changed file\) \([^ ]*\) file.*$/\1/p;s/^.*t open \([^ ]*\) file.*$/\1/p' < /tmp/broken.log |  sort -u > /tmp/broken.pkgs
cd /var/cache/apt/archives
rm  `cat /tmp/broken.pkgs`
apt-get --reinstall install `cat /tmp/broken.pkgs`

or

Try organize dpkg: https://help.ubuntu.com/community/PackageManagerTroubleshootingProcedure
