Remove old kernels

Read the following as background;

Then do the following in a terminal;

sudo apt-get install byobu

'byobu' is a handy terminal multiplexer. Among others, it is very useful when you want to leave a process running after closing your terminal (you cannot do this with the "common" Terminal). However, there is another reason to install byobu. purge-old-kernels is a simple bash script, which uses apt remove --purge command to remove old kernels. It will be available in your system after installing package byobu
