Script that helps to remove unused kernels from an Ubuntu (and possibly also Debian) Linux system.

See this question from Ask Ubuntu for the original problem.

Install the package with pip:

sudo pip install git+http://github.com/mrts/ubuntu-old-kernel-cleanup.git

Verify that the script was installed successfully by running it:

ubuntu-old-kernel-cleanup

Do a dry run first to see what would be removed:

ubuntu-old-kernel-cleanup | xargs sudo apt-get --dry-run purge

Then run the actual cleanup:

ubuntu-old-kernel-cleanup | xargs sudo apt-get -y purge
