What happened here is that we dropped the 510 driver in lrm
5.4.0-135.152+1, transitioning it to the 515 driver. It therefore did
not produce a 5.4.0-135.152+1 version of linux-modules-
nvidia-510-server-5.4.0-135-generic. Ubuntu always keeps the latest
version of a binary package in the archive, even if the source that
produced it has been superseded. Because of that, the 5.4.0-135.152
version of linux-modules-nvidia-510-server-5.4.0-135-generic is sticking
around. 5.4.0-135.152 correctly had a strict versioned dep on a matching
linux-signatures package, and that linux-signatures package was
superseded by a new one. Superseded packages *are* dropped from the
archive, so that dependency can no longer be met.
TLDR; this is all normal (though not ideal) behavior, and this one is
particularly confusing because we dropped (and transitioned) the 510
driver during a refresh of the drivers for a kernel that previously had
a 510 driver.
Lesson: Installing modules for anything other than the latest kernel
update is not supported, even if those modules appear to still be
available in the archive.
