Today’s update included, among others, linux-lts 5.10.76-1 -> 5.10.77-3. There were two lines in the output (attached as a pdf file) which maybe of concern.
These are lines #42 and #53: 42 ==> Unable to remove module r8101/1.035.03 for kernel 5.10.76-1-lts: Not found in dkms status output.
and 53 ==> Unable to install module r8101/1.035.03 for kernel 5.10.77-3-lts: Missing kernel headers.
