Is there a dockerfile based on ubuntu that would install regolith with RDP/VNC support?

[voidfire]

I believe it would be easy if someone is familiar with Regolith to make a dockerfile that uses an ubuntu image, installs regolith desktop on top of it and then xrdp and xrdp-sessions
I tried to do that but I failed installing regolith repos as explained here: https://regolith-desktop.com/
I was getting an error about the repository ... jammy having no release file
