apt-get and rsyslog

I'd move to tty e.g.
ctrl+alt+f1
and try some repair commands.
apt-get -f install rsyslog
dpkg --configure -a

or recovery mode (has an option to repair packages).

Please could you telle me how to enter in the "recovery mode" that should repair packages ?

luciano

My understanding is that the problem only affects Version: 4.2.0-2ubuntu5.1 of rsyslog package
and not the Version: 4.2.0-2ubuntu5 (installed by default with Ubuntu 9.10).
Unfortunately i run the apt-get update and apt-get upgrade commands that led me to install the latest
(bugged ?) version.
So it is possible to go back to the original Version: 4.2.0-2ubuntu5 ?
Thank You again.
Happy new year.

Unfortunately no.

Although it's a mystery why an upgrade helped this user.
