Comment 17 for bug 1605948

i read a solution in stack overflow that worked for me. i have changed the socket location to tmp/mysql.sock in my.cnf. So when the upgrade script searched for it, was not able to find it (dfault location was var/lib/mysql.sock). So i changed debian.cnf in //etc/mysql/ to the particular socket mysql server was actively running and voala!! everything worked perfect.. cheers...
