  • Just FYI it is much more useful to include text as text in your question (since it can be searched by search engines) than to paste an image. – Kurankat Apr 20 '20 at 04:39

To remove old kernel versions on Ubuntu 18.04 or above :

sudo apt-get -y --purge autoremove

To remove old Kernel Ubuntu 16.04 LTS and older :

sudo -i
apt-get -y --purge remove $(dpkg --list | egrep -i 'linux-image|linux-headers' | awk '/ii/{ print $2}' | egrep -v "$i")

First, reboot your PC, and then check the current kernel the OS is using:

uname -r && sudo update-grub

second, list the kernels

dpkg -l | grep linux

third, compare the output of the first step with the second step.

finally, sudo apt purge <all-of-the-old-kernel-name>
