Thanks for reporting this According to your error log, seems that there is already a process running in the same port:
131026 8:25:13 [ERROR] Can't start server: Bind on TCP/IP port: Cannot assign requested address 131026 8:25:13 [ERROR] Do you already have another mysqld server running on port: 3306 ? So you should check which process is already using it, and solve that conflict. ** Changed in: mysql-5.5 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1244946 Title: package mysql-server-5.5 5.5.34-0ubuntu0.12.04.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.5/+bug/1244946/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
