Bug Description

[ Impact ]

pychess is completely unusable as it will fail to start and will give error while trying to start the splash screen.

The error:

/usr/games/pychess:17: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '4.0') before import to ensure that the right version gets loaded.
from gi.repository import Gtk, Gdk
Failed to create splash screen
ERROR: Not all dependencies installed! You can find them in INSTALL
Namespace Gdk is already loaded with version 4.0

[ Test Plan ]

* Execute pychess, which will fail to start if its not fixed.
* With the fixed package, pychess will start and we can play a small game of chess to verify it works.

[ Where problems could occur ]

This is an upstream patch and is not changing any part of the code. Its only specifying the Gtk version that should be loaded. Since the screen is displayed with this change the chances of regression are very small.

[ Other Info ]

* It has been fixed by upstream in v1.0.1 and so later releases after Jammy are not affected.

[ Original Bug Description ]

Running from the command-line:

Really quick, just adding that line results in a situation where pychess just won't work with Python 3.9 that's installed. I tried adding Python 3.7 with deadsnakes to try that out, but their jammy repo isn't up yet.

Should probably pull in the latest version from here: https://github.com/pychess/pychess/releases

python3-pychess_1.0.3-1_all.deb seems to work fine.

After installing stockfish manually, yes :)

Looking at the (other) dependency differences:

$ dpkg -I /var/cache/apt/archives/pychess_1.0.0-1.2_all.deb
...
Depends: python3:any, gnome-icon-theme, python3-cairo, python3-gi, python3-gi-cairo, python3-pexpect, python3-sqlalchemy, python3-psutil, python3-websockets, gobject-introspection, gir1.2-glib-2.0, gir1.2-gtk-3.0, gir1.2-pango-1.0, gir1.2-rsvg-2.0, gir1.2-gdkpixbuf-2.0, gir1.2-gtksource-3.0, gir1.2-gstreamer-1.0, gir1.2-gst-plugins-base-1.0, libgaviotatb1, gaviotatb
...

Versus:

$ dpkg -I ~/Downloads/python3-pychess_1.0.0-1_all.deb
...
Depends: python3:any (>= 3.4~), gnome-icon-theme, python3-gi, python3-gi-cairo, gobject-introspection, gir1.2-glib-2.0, gir1.2-gtk-3.0, gir1.2-pango-1.0, gir1.2-rsvg-2.0, gir1.2-gdkpixbuf-2.0, gir1.2-gtksource-3.0, python3-cairo, python3-sqlalchemy, python3-pexpect, python3-psutil, python3-websockets, stockfish
...

And:

$ dpkg -I ~/Downloads/python3-pychess_1.0.3-1_all.deb
...
Depends: python3:any (>= 3.4~), gnome-icon-theme, python3-gi, python3-gi-cairo, gobject-introspection, gir1.2-glib-2.0, gir1.2-gtk-3.0, gir1.2-pango-1.0, gir1.2-rsvg-2.0, gir1.2-gdkpixbuf-2.0, gir1.2-gtksource-3.0, python3-cairo, python3-sqlalchemy, python3-pexpect, python3-psutil, python3-websockets, stockfish
...

Only thing other than stockfish (which is not the missing dependency that solves the issue) I only notice the Ubuntu package is asking for gaviotatb and libgaviotatb1 (but still fails) while the github package works fine without those.

When multiple versions of Gtk are available you must specify the required version before importing. In this case when it is first imported it is not specified so PyGI picks 4.0 and warns you.

Then later the program imports Gtk again when checking dependencies, but this time specifying the needed version (3.0), which fails as 4.0 was already loaded. This patch fixes the warning and the subsequent failure:
