kernel_up2date no longer works on Bullseye (and Bookworm)
kernel_up2date
no longer detects the newest running kernel correctly on Bullseye.
The culprit seems to be that grep-status -n -s Depends -P linux-image-amd64
not only reports the package name but also a package version eg.
λ › grep-status -n -s Depends -P linux-image-amd64
linux-image-5.10.0-26-amd64 (= 5.10.197-1)
Also effects the 5.10 backports kernel on Buster.
