[Bug 1873867] Re: ubuntu-drivers changes kernel flavour when installing nvidia

[Launchpad Bug Tracker]

This bug was fixed in the package ubuntu-drivers-common - 1:0.8.1

---------------
ubuntu-drivers-common (1:0.8.1) focal; urgency=medium

  [ Alberto Milone ]
  * UbuntuDrivers/detect.py,
    UbuntuDrivers/kerneldetection.py,
    tests/test_ubuntu_drivers.py,
    ubuntu-drivers:
    - Add tests for the -generic-hwe-20.04 flavour and for
      the -oem-20.04 linux flavour.
    - Add detection logic to get the linux metapackage and
      linux-modules for -hwe-20.04 (LP: #1873867).
    - List the modules provider when it is either a dkms package
      or a linux-modules package.
    - Install linux-modules packages when available.
      This makes the NVIDIA drivers work with Secure Boot.

  [ Dimitri John Ledkov ]
  * UbuntuDrivers/detect.py,
    UbuntuDrivers/kerneldetection.py:
    - Use exact matching in find_reverse_deps() with both
      installed and candidate.

  I was expecting for it to pick linux-modules-nvidia-440-generic-
  hwe-20.04 not linux-modules-nvidia-440-lowlatency-hwe-20.04

  As if it sorted things and picked last one?
