Bug#1008557: gnome-shell-extension-system-monitor: does not declare compatibility with GNOME Shell 42

[Simon McVittie]

Package: gnome-shell-extension-system-monitor
Version: 40-3
Severity: normal
Tags: bookworm sid fixed-upstream
User: pkg-gnome-maintainers at lists.alioth.debian.org
Usertags: gnome-shell-42
Forwarded: https://github.com/paradoxxxzero/gnome-shell-system-monitor-applet/pull/736

The metadata.json for this extension doesn't declare compatibility with
GNOME 42. According to upstream git, no actual code changes are needed
(not verified, so please test).

gnome-shell 42 is in experimental and will be entering unstable soon,
at which point this will become a RC bug.

In versions of GNOME Shell up to 3.38, metadata.json didn't matter much,
because validation of extensions' metadata against the installed Shell
version was disabled by default; but since GNOME 40 the default has changed
back to enabling the version check by default, in an effort to avoid
issues caused by outdated extensions remaining enabled. As a result,
GNOME Shell extensions in bookworm should probably have a dependency like:

    Depends: gnome-shell (>= x), gnome-shell (<< y~)

where x and y are set according to metadata.json.
gnome-shell-extension-caffeine is a good example of this technique.

During the GNOME Shell 42 transition, this extension will be removed from
testing if it continues to be incompatible.

Thanks,
