How to remove/uninstall a useless Kernel [SOLVED]

[Magister]

you can also do it with:

sudo apt-get purge linux-headers-4.19<PRESS TAB HERE> linux-image-4.19<PRESS TAB HERE>

Don't know your option it can be 686, pae etc so when you press TAB after typing the beginning of a package it will auto complete and show you the choice. The purge option will also remove the .deb files

Take care not to remove your running kernel here, though the system will warn you quite strongly if you try that. You don't get the warning if removing the current headers, though, and that can lead to trouble down the road.
