My grub has the following versions which I want to remove.
- Ubuntu, with Linux 4.1.0-rc5-next-20150529
- Ubuntu, with Linux 4.1.0-rc5-next-20150529.old
- Ubuntu, with Linux 4.1.0-rc4-next-20150525
- Ubuntu, with Linux 4.0.0-rc6-next-20150402+
- Ubuntu, with Linux 4.0.0-rc6-next-20150402+.old
I tried the following methods to remove:
Using Synaptic tool and I have typed the following commands:
uname -r
dpkg --list | grep linux-image
sudo apt-get purge linux-image-x.x.x.x-xyz
sudo update-grub2
Both of the methods failed to remove the kernel versions.
