Q:

Unable to update ubuntu applications because there is not enough space on /boot

I am unable to update ubuntu because there is not enough space on /boot. Some googling has shown a lot of people have this issue but the reason for /boot being full is different for everyone and everyone has to take slightly different steps to solve the issue.
Here are the outputs of various commands I have seen requested of people posting about this problem
$ls -l /boot

$ uname -r
3.13.0-32-generic

Does anyone know how to solve this? Any help would be appreciated.

A:

Just uninstall the old kernels:
sudo apt-get remove --purge linux-image-3.11.0-XX-generic

(Where 'XX' is the version number of the kernel you want to remove)
