Ubuntu 18.04 and "sig_hashalgo: md4"

[Dimitri John Ledkov]

Hey,

linux kernel upstream has changed how signatures look like in
v5.2-rc1, and only kmod 27 learned how to parse them. But bionic ships
kmod 24, meaning with hwe / cloud kernels, the information printed by
e.g. modinfo is incomplete.

Normally bug reports should be opened in launchpad, i have done so now
at https://bugs.launchpad.net/ubuntu/+source/kmod/+bug/1894611

If this is time critical for you, you could install kmod from focal on
your bionic system (or use it from chroot).
