I have tried removing the 5.17.0-1014 kernel with the command:
sudo apt remove linux-image-5.17.0-1014-oem
And apt suggests to install linux-image-unsigned-5.17.0-1014-oem.
To remove the kernel I have typed the command:
sudo apt remove linux-image-5.17.0-1014-oem linux-image-unsigned-5.17.0-1014-oem
Is it normal behavior of apt?
