After an upgrade from etch to lenny, the bastille firewall will not run any more:

• Starting up will give you an error message about a missing /sbin/bastille-ipchains file
• Reconfiguring (which would create that file) fails because DB5.0 is not supported

The problem: DB5.0 was not added to the supported OS lists in the debian lenny release.

The fix:

• Add DB5.0 to the files: /usr/lib/Bastille/API.pm and /usr/lib/Bastille/IOLoader.pm
• In API.pm change $stable=“4.0” to $stable=“5.0”
• Run InteractiveBastille (your existing config file will be used to populate answers, no worries!)

After this, /etc/init.d/bastille-firewall start should work.

1. Edit sources.list

sudo vi /etc/apt/sources.list

and change all words etch to lenny, or stable to testing (vim: :s/etch/lenny/g)

2. Update and upgrade

sudo aptitude update
sudo aptitude install apt dpkg aptitude
sudo aptitude full-upgrade

that is all, this also work if you want to go from lenny to sid, just change your sources.list accordingly.

It is also better if you start your Debian Linux in text mode, so GDM or KDM could be restarted without problems.

After the upgrade:
