I'm running KUbuntu 18.04.3 and have applied the HWE updates that change from a 4.15.x kernel to 5.0.0x kernel. I've done the HWE "update" on a
16.04LTS system and after doing so, the old kernel versions were no longer offered. This doesn't happen for me on 18.04. When I run the KDE update
tool, and there's a new kernel offered, I have to manually uncheck the 4.15x items offered. What's going on??
