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
