Comment # 4 on bug 1082704 from Peter S�tterlin

No, of course the weak-update links are as they should be.  But it should be
the 4.15.2 module in /lib/modules/4.15.2-1-default/updates.  It obviously is
not.

Here's the dmesg when I tried to manually load the module in kernel 4.15.2 (I
had booted to runlevel 3, logged in on console and typed the modprobe command):

Feb 24 20:07:05 lux login[1775]: ROOT LOGIN ON tty1

There were similar/identical messages earlier in the boot, as the machine is
nvidia-only, and the module is supposed to load already from initrd, which of
course also failed.

It is supposedly the same issue that you requested a separate report for in
