[Łukasz Zemczak]

Hello Brian, or anyone else affected,

Accepted ubuntu-release-upgrader into cosmic-proposed. The package will
build now and be available at https://launchpad.net/ubuntu/+source
/ubuntu-release-upgrader/1:18.10.11.7 in a few hours, and then in the
-proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-cosmic to verification-done-cosmic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-cosmic. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in

N.B. The updated package will be released to -updates after the bug(s)

Title:
  KernelRemoval section is out of date

Status in ubuntu-release-upgrader package in Ubuntu:
  Fix Released
Status in ubuntu-release-upgrader source package in Bionic:
  Fix Committed
Status in ubuntu-release-upgrader source package in Cosmic:
  Fix Committed
Status in ubuntu-release-upgrader source package in Disco:
  Fix Committed

Bug description:
  The dist-upgrader tarball includes configuration files for the release
  upgrade process and part of the configuration file is a section with
  the heading KernelRemoval which includes Version, BaseNames, and Types
  which are used to build a list of kernels to remove. This section has
  not been updated in quite some time and we should up date so systems
  have less old kernels installed.

  [Test Case]
  1) upgrade a system from a release of Ubuntu to a new release of Ubuntu (this should be done for the following paths B->C, C->D, B->D)
  2) observe the following in /var/log/dist-upgrade/main.log
  "2019-05-07 11:38:23,264 DEBUG identifyObsoleteKernels()
  2019-05-07 11:38:27,621 DEBUG identifyObsoleteKernels found 'set()'"

  The release upgrader from -proposed (do-release-upgrader -p) should
  identify some obsolete kernels ("skipping running kernel linux-
  headers-5.0.0-13-generic") even if it doesn't end up removing them.

  [Regression Potential]
  I made the BaseNames section split out across multiple lines which should be fine but that could cause the config file to fail to be parsed which would probably cause a crash or the same failure to remove obsolete kernels.
