*** This bug is a duplicate of bug 1863261 ***

I do not believe this is a duplicate; It is more likely a *packaging*
issue. The question remains for this bug, why does it only appear in
the focal kernels; but not Eoan or older?
And if someone could confirm whether or not the linux-generic or linux-
modules generate this file and when (unpack, deb postinst, kernel
install hook?)
Another reason why this isn't a duplicate as the error message is
unrelated to the contents of the initrd, but rather when depmod -a -S is
called (postins of linux-modules package).
On Eoan we can remove the file in question and regenerate the file with:
depmod -a -F /boot/System.map-5.3.0-40-generic;
this command does not produce the error message on any release expect
Focal.
