Comment 20 for bug 64615

I had the same problem as zek725.

It seems that the package is not installed and abviously can not be stooped.

My solution was to create an empty courierlogger file :

touch /usr/sbin/courierlogger
chmod +x /usr/sbin/courierlogger

also the /var/run/courier dir must be made empty. I only had a subdir nammed calendar, which i removed.

rmdir /var/run/courier/calendar/

After this i could install courier-authlib, do a 'install -f' and complete the upgrade.

apt-get install courier-authlib
apt-get install -f
apt-get dist-upgrade

Maybe this can help You zek
