This problem is resolved only after the following lines aptitude purge mysql-server mysql-server-5.5 mysql-client mysql-client-5.5 mysql-common
removing mysql-common removed dozens of other packages, which I copied and now reinstalling. after that I removed the mysql etc folder sudo rm /etc/mysql/ -R and reninstalled the mysql sudo aptitude install mysql-server mysql-client This resolves the problem, however the bug is there and should be sorted out.
