I was reading the modprobe manual: https://linux.die.net/man/8/modprobe
So I tried the -l flag on a few different Ubuntu machines: 18.04, 20.04.3
After getting:
modprobe: invalid option -- 'l'
I noticed that indeed "-l" is missing when running modprobe -h.
If it helps, modprobe -V gives the following version number:
mod version 27
+XZ -ZLIB +LIBCRYPTO -EXPERIMENTAL
Can someone shed some light - how can I get modporbe with "-l" flag?
