Bug Description

The ubuntustudio installs only the lowlatency kernel, but when upgraded the generic kernel gets added and also becomes the default kernel. This makes lowlatency audio recording not work. The generic kernel should not be installed.

It appears that when the script get-kernel_list.sh is run, it does not return linux-lowlatency as one of the options and so the calling script first tries to find linux-RT and fails and then settles on generic instead.

(the above was found while looking through /var/log/dist-upgrade/main.log)

Discussed in ubuntu-devel:

11:56 < slangasek> cull the code
11:56 < infinity> I'm all for the culling.
11:58 < bdmurray> So just remove the kernel checks from
                  ubuntu-release-upgrader altogether
                  correct?
11:58 < infinity> Bonus points if you can find the
                  original commits to sort out what to
                  revert.
11:58 < infinity> But basically that, yes.
11:59 < infinity> I think there is (or used to be) logic
                  that tries to make sure you have
                  "linux-$flavour" installed, matching
                  the running kernel. That's probably a
                  sane thing to do.

This bug was fixed in the package ubuntu-release-upgrader - 1:0.203

---------------
ubuntu-release-upgrader (1:0.203) saucy; urgency=low

  [ Brian Murray ]
  * test/test_sources_list.py: resolve test failure regarding EOL upgrades
  * DistUpgradeQuirks.py: pep8 cleanup, remove some additional unnecessary
    quirks
  * DistUpgrade/patches/: remove pycompile patch

  [ Steve Langasek ]
  * Drop all quirks for upgrades prior to the karmic->lucid upgrade; all
    releases earlier than 10.04 are entirely EOLed, and in any case users
    should not be upgrading directly from such old releases to 13.10 or
    later without going through the intermediate LTS releases, so this is
    all dead code.
  * Drop use of base-installer for detecting "recommended" kernels for the
    hardware. So far this code was only ever used for a one-time transition
    when more specialized kernel flavors became available on i386 that were
    preferred over the -386 flavor, and in the meantime the code is causing
    wrong results on upgrade for users of UbuntuStudio, which ships a kernel
    flavor that's not known by base-installer. LP: #1220898.
