Source: live-build
Version: 1:20240810
Severity: serious
X-Debbugs-Cc: bluca@debian.org

Hi,

I'm letting this bug have RC severity because:

 - it interferes with files installed by another package (base-files) without
   coordination on actual user installations (not just during a live session)
 - the information "what release am i on" is a crucial part of what the OS
   should report correctly to the user (and to utilities querying the
   information)

I'm CC-ing Luca because the problem got introduced by this commit in
live-build:

https://salsa.debian.org/live-team/live-build/-/commit/24bfe093f82ccc134ab5d91fb4058ee0b52ec942

The commit is over a year old but the problem only showed now as users are
upgrading their installations that they made from a Debian Live CD from
Bookworm to Trixie.

The problem is this dpkg diversion:

mmmm@mmmm-linuxdummyvirt:~$ dpkg-divert --list | grep os-release
local diversion of /etc/os-release to /etc/os-release.debootstrap

According to the commit message the diversion is supposed to guard against
potential upgrades of base-files overwriting the contents of /etc/os-release
with its own contents. The problem is, that the calamares installer which can
be used from a Debian Live CD to permanently install Debian, creates a copy of
the Debian Live system and installs that to the disk. This includes the
diversion which was only meant for the live system itself.

There are multiple things to fix here:

 1. live-build itself should clean up the diversion after it is done installing
    (and potentially upgrading) the packages that end up on the live CD. The
    diversion is not useful anymore on the running Debian Live system itself.
    Once that is done, new installations made with Calamares will no longer
    include that diversion for the upgrade from Trixie to Forky.

 2. existing installations of Debian Bookworm that were made with Calamares
    from the Debian Live CD should somehow have the diversion cleaned up such
    that the contents of /etc/os-release after the upgrade reflect what
    base-files ships. Since a system installed from a Debian Live CD with
    calamares also installs the live-* packages, maybe a new upload of
    live-config or live-tools could contain a postinst maintainer script which
    performs the necessary magic?

Maybe the second part should be done quickly because there are a bunch of
users out there which are currently very confused by this issue:

 - https://www.reddit.com/r/debian/comments/1mmbjdh/old_etcosreleases_file_after_upgrading_to_debian/
 - https://www.reddit.com/r/debian/comments/1mmldrq/upgraded_to_debian_13_but_still_showing_as/
 - https://www.reddit.com/r/debian/comments/1moe5bz/trixie_upgrade_doesnt_upgrade_etcosrelease/

Unfortunately I don't have a reddit account, so I cannot be of further
assistance on that platform.

Thanks!

cheers, josch
