[Bug 1828100] Re: KernelRemoval section of DistUpgrade.cfg shouldn't require manual updating

[Balint Reczey]

I'm wondering if we still need this functionality in u-r-u.

It offers removing removal of all autoremovable packages at the end of
the upgrade for a long time and kernels are autoremoved periodically by
unattended-upgrades and update-manager in Xenial and up.

IMO those are enough and since u-r-u performs autoremoval after the
upgrade it is not affected by apt's LP: #1615381.

** Changed in: ubuntu-release-upgrader (Ubuntu Eoan)

Title:
  KernelRemoval section of DistUpgrade.cfg shouldn't require manual
  updating

Status in ubuntu-release-upgrader package in Ubuntu:
  Confirmed
Status in ubuntu-release-upgrader source package in Eoan:
  Confirmed

Bug description:
  Currently the method to determine kernels to auto remove uses a hard-
  coded version number and package base names in DistUpgrade.cfg. This
  need to be updated for every release of Ubuntu and has been missed in
  the past - bug 1828072. It'd be better if the autoremovalable kernels
  did not need to be updated all the time and instead utilized the logic
  apt uses (/etc/apt/apt.conf.d/01autoremove) to determine what kernels
  are removable.
