That list is not entirely correct, duplicity claims support for Python 2.7, 3.6 and 3.7.

For me it very much still is.

I'm seeing the same issue, had a few broken unrelated packages which are now fixed. Didn't help.
The overlay works when using the native runtime, which I'm currently not using because of Proton issues in the past.

The issue is also tracked on Steam's side over here: https://github.com/ValveSoftware/steam-for-linux/issues/6155

I'm bad at kernel debugging. The dmesg log is not being persisted on these failed boots, meaning journalctl -k -b -1 shows me only the last successful boot on the .5 Kernel.

@DataDrake I would consider this task done and ready to be closed now, wouldn't you?

With thew new Steam Play announcement (https://steamcommunity.com/games/221410/announcements/detail/1696055855739350561) it's really due time to get this ball rolling.

At this point I'd take any solution but I'd like to keep it simple.
Just another package that is labelled unstable or something.

This remains a viable issue as Rise of the Tomb Raider just released for Linux and requires the latest beta drivers for optimal performance.

MinGW would really be useful for cross compilation in general.

The current relevant beta driver now is version 390.xx http://www.nvidia.com/download/driverResults.aspx/128743/en-us

If I've understood correctly the driver GUI is going away and there's just going to be a prompt that opens the SC?

Yes, packaging beta drivers would help my specific case and I'm certainly the last guy to say no to that but it wouldn't really help the other cases
with WiFi drivers and other less common hardware.

I also need DKMS to make using the Nvidia beta drivers feasible, which I need to make full use of my HTC Vive VR headset.
The assumption that pre-packaged drivers are always enough for everybody sadly has no basis in reality.
