[Bug 2086506] Re: Upgrade to 24.10 deletes unmigrated apt sources

[Nick Rosbrook]

Can you please run `apport-collect 2086506` to attach logs etc., so we
have a better idea of what happened? Can you also share the contents of
/etc/apt/sources.list.d/ after the upgrade?

I do not completely follow what you are describing. Are you saying that
unused/disabled sources were removed? Or that some *enabled* source you
expected to be migrated to deb822 was not actually migrated?

Title:
  Upgrade to 24.10 deletes unmigrated apt sources

Status in ubuntu-release-upgrader package in Ubuntu:
  Incomplete

Bug description:
  During previous upgrades, most of my one-line-style sources (.list) in
  /etc/apt/sources.list.d were not migrated to deb822 style (.sources)
  (I believe because I added the signed-by option to them), and were
  left disabled (renamed to .list.distUpgrade) after the upgrade.

  The upgrade from noble to oracular again did not migrate the one-line-
  style sources, however it deleted the source files instead of keeping
  them disabled.

  Luckily I have etckeeper installed so I was able to restore the files
  and spend the (IMHO unnecessary) time to convert them to deb822 format
  so that nothing like this will happen again.

  Looking at the git history, it appears the .list files were renamed to
  .list.migrate without adding a corresponding .sources file (and
  without renaming/copying the .list file to .list.distUpgrade), then
  later the .list.migrate files (and .list.distUpgrade files of
  successfully migrated sources) were deleted.

  I have been through 20+ Ubuntu upgrades, and there has been times when
  something went wrong and I had to fix the upgrade in some way, but
  this is the first time the process has deleted my configuration files
  without any notice or error message. My guess is this is an
  unintentional programming error, but I am still deeply disappointed.
