Bug description

I installed it yesterday from flathub and it worked fine, today, after system update which upgraded the kernel to version 6.6.20+rpt-rpi-v8 it no longer launches. It crashes every time, reinstalling the package did not solve the issue.

kotyz@raspberrypi:~ $ flatpak run org.x.Warpinator

ValueError: invalid literal for int() with base 10: '20+rpt'

Steps to reproduce

Click on the Warpinator shortcut in the start menu - nothing happens.
Launch it from terminal with the flatpak run org.x.Warpinator command - it spits out some traceback call and exits.

Expected behavior

Application should launch if I click on its shortcut in the start menu or if I launch it in the terminal with the flatpak run org.x.Warpinator command.

Seems like the kernel version is unable to be parsed: the + symbol is unexpected.

In [4]: tuple(map(int, "6.6.20+rpt-rpi-v8".split("-")[0].split(".")))

In [5]: 

What was the version string on the previous kernel? Seems like they need to fix this

[kotyz85]

Previous kernel version is 6.1.0-rpi8-rpi-v8

I recently built deb package from source and I'm getting exactly the same error. So it's likely not dependent on packaging format, flatpak or deb.

You're right, it's because of the + in the kernel version.

You can try modifying warpinator-launch.py:
