I tried remove and purge and autoremove
sudo apt-get remove linux-image-4.15.0-58-generic
sudo apt-get purge linux-image-4.15.0-58-generic
sudo apt-get autoremove
I'm currently logged in 4.15.0-55-generic. I tried to remove 4.15.0-58-generic which caused login loops. I tried to reboot again and I can only login 4.15.0-55.
Sometimes I get this error. I don't know how to go to this directory and check what's in it. rmdir: failed to remove '/lib/modules/4.15.0-58-generic': Directory not empty
I also don't know why there are so many images.
Thank you
