I have tried every other solution that I could find on stack overflow and elsewhere on the Internet.
The solutions that i have tried include purging mysql,autoremove,autoclean,dist upgrade,reboot,removing /etc/mysql /var/lib/mysql and almost every other thing that I could find related to this problem.It is not helping me, and now asking this question because no other answers were helping me.I am not worried of losing any DB that I might I have on my system.
I must add that since installing mysql was not working for me,I went with mongodb.It installed fine initally ,but now even removing and installing mongodb is givinf the same Error.
