package python-ibus 1.5.5-1ubuntu3 failed to install/upgrade: subprocess new pre-removal script returned error exit status 1

[Joe]

I was trying to install python mysql connector mysql-connetor db. I am using Python 3.
Further I used import mysqldb, since it was not responding I force quit.
Now even the Ubuntu Software Centre is not starting. I may have done something wrong without knowing.
Please help. Thanks
