[Bug 963011] Re: dkms package causes linux-headers-* packages stay in the system forever consuming disk space

[Vasya Pupkin]

You are wrong. When dkms package is not installed, on kernel upgrade old
headers are automatically deleted. You can verify that yourself. The
problem is that dkms package has "linux-headers" in dependencies which
is a virtual package that lists all possible versions of linux-
headers-*. It should instead depend on either of linux-headers-generic,
linux-headers-server, linux-headers-virtual, etc. These metapackages
always depend on latest version of linux-headers-* allowing old headers
to be automatically uninstalled.

It's not a bug in dkms itself, but a bug in it's packaging.

Title:
  dkms package causes linux-headers-* packages stay in the system
  forever consuming disk space

Status in “apt” package in Ubuntu:
  New
Status in “dkms” package in Ubuntu:
  Invalid

Bug description:
  Because of some veird dependency in dkms package, on each kernel
  upgrade old linux-headers-* packages are not getting removed,
  consuming a lot of disk space. Finally, root partition runs out of
  space which causes serious issues. Without dkms, everything works
  fine. I checked dependency and it indeed recommends all old packages.
