i'm no longer sudo and can't login in my account on Ubuntu 12.10
 

As the title said I have problems with getting into my account.I enter my password(which is definitly the right one) but it just keeps returning me back to the login screen.Also I can't use sudo anymore.I tryed to add myself to the sudo group using the recovery mode but it is saying:"can't lock /etc/group;try later".When I try to mount to rw it is telling me that it is alredy mounted.So guys please help me with this problem because I love my Ubuntu and I don't want to go back to windows

I would initially presume that you might have some kind of filesystem damage. You need to start with "fsck."

But, in general, obviously "a lot more 'just happened' .. :eek: .." and that is what you need to tell us.

thanks for the reply..i did fsck and it said:"/dev/sda1: 200249/395136 files (0.4% non-contiguous), 1226595/1579776 blocks"

why is nobody helping me??
