# Build environment for the Lutris AppImage proof-of-concept.
#
# Ubuntu 22.04 is chosen as a balance between glibc backward compatibility
# (glibc 2.35) and shipping Python 3.10 + GTK3 + WebKit2GTK 4.1 in the
# distro repos. If we promote this from PoC to a supported channel, we
# may want to drop to 20.04 (glibc 2.31) for wider portability.
