So I was installing Kolab over an OpenVZ Debian 7 Minimal image on Proxmox, and half the install I find this error:
Stopping MySQL database server: mysqld. /var/lib/dpkg/info/mysql-server-5.5.postinst: line 146: logger: command not found ATTENTION: An error has occured. More info is in the syslog! /var/lib/dpkg/info/mysql-server-5.5.postinst: line 236: logger: command not found dpkg: error processing mysql-server-5.5 (--configure): subprocess installed post-installation script returned error exit status 127 dpkg: dependency problems prevent configuration of mysql-server: mysql-server depends on mysql-server-5.5; however: Package mysql-server-5.5 is not configured yet.
So the postinstall scripts found something they are not able to run. I’ve been scratching my head for a while until I found on a russian website I needed the bsdutils package:
apt-get install bsdutils
