Can't start MySQL5.5 on Ubuntu 12.04 - “dpkg: dependency problems”
This appears to be a common problem on 12.04. I've tried everthing in this thread including: sudo apt-get clean sudo apt-get autoclean sudo apt-get remove --purge mysql-client-5.5 mysql-client-core-5.5 mysql-common mysql-server mysql-server-5.5 mysql-server-core-5.5 sudo apt-get install mysql-server I still get the same old error. Installing/starting MySql5.5 looks like this: apt-get install -f mysql-server Reading package lists... Done Building dependency tree Reading state information... Done mysql-server is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not
