Arch Linux User Repository

After the Python 3.12 upgrade, I get this error (rebuilding does not help, unfortunately):

Traceback (most recent call last):

    return next(cls.discover(name=name))
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
StopIteration

During handling of the above exception, another exception occurred:

pkgver is in wrong format with bad semantics. Please use standard #.r#.g# format as specified in VCS package guidelines.

Currently, showing diffs is proken with python 3.11.

A fix is to apply this patch until upstream maintainers have merged it (it seems a bit upstream is abandoned since no update to the repository for a while, let's see).

Was able to make and install the package without problem, but then couldn't open any snapshots...made sure all permissions were set correctly...opened via terminal and saw the following error message whenever I hit "Open":

Traceback (most recent call last):
  File "/usr/lib/python3.10/site-packages/snappergui/mainWindow.py", line 141, in on_open_snapshot_folder

Installed xdg-utils package and no more issues. Maybe add that as a depends?

@SkorpEN: Those are already dependencies, what do you mean? Please unflag the package, it's not out date.

python-dbus seems required other dependencies from https://github.com/ricardomv/snapper-gui python-gobject python-setuptools Rest seems not really needed in newer gtk.
