How can I remove a package?

Question

How to remove linux-image-extra-3.13.0-49-generic from my system?

I can't install any package because of this error:

$ sudo apt-get autoremove
Reading package lists... Done
Building dependency tree

It's not the same as http://askubuntu.com/questions/89710/how-do-i-free-up-more-space-in-boot question as apt-get purge xxx doesn't work(the same error).

Answer 1

I've searched lots of answers and tried every one I can with no luck.

the sudo apt-get -f install and sudo apt-get install otherpackage all get the same error as above in the end:

I can't install or remove any packages. The solution is simple(It took me one day):

Just download vmlinuz-3.13.0-49-generic.efi.signed file to /boot folder, then run sudo apt-get autoremove

Since then everything is ok. Thanks all for you help and time!
