[Bug 2024483] Re: Ubuntu links missing or broken in /usr/share/debootstrap/scripts

[Steve Langasek]

Actually, the above test without lunar-proposed also didn't have arch-
test installed, I didn't notice the error message there was unrelated to
debootstrap.

So in fact, it appears that pbuilder-dist does NOT fail with the
debootstrap symlinks removed, it only throws a prompt which the user can
bypass.

Bug description:
  [Justification]
  Fix for an SRU regression.  The previous SRU dropped the 'scripts' symlinks for all recent Ubuntu releases because the links were no longer needed for debootstrap's internal use.  However, this broke compatibility with third-party code which (unnecessarily) hard-coded the script argument to debootstrap.

  [Test case]
  1. apt install ubuntu-dev-tools pbuilder arch-test
  2. pbuilder-dist jammy create

  [Where things could go wrong]
  Provided the diff contents are correct, this is a straight revert of a change from the preceding SRU and should not regress behavior.  The revert means that  when bootstrapping the releases that were manually added before, debootstrap will follow the symlink instead of using the new code, which in inconsequential.

  [Original description]
  debootstrap package does not have links for many Ubuntu versions in /usr/share/debootstrap/scripts. In particular, jammy is missing.

  See the file list:

  https://packages.ubuntu.com/jammy-updates/all/debootstrap/filelist

  Also, /usr/share/debootstrap/scripts/hirsute link points to groovy,
  which is also missing (i.e. hirsute is a broken symlink).

  This breaks pbuilder, which no longer recognizes distro names and
  fails with errors like this:

  Warning: Unknown distribution "jammy". Do you want to continue [y|N]?
  Aborting as requested.
