I've updated first line of dockerfile to be FROM ubuntu:20.04. docker build works now. will submit pull request

@sfeaster Thanks! I will watch for your PR.

It looks like this change has already been made in the main branch, it just was not the case with the last release. I continue to have issues building the container on macOS 12.13.1 with the Ubuntu 20.04 in-place.

[machawk1]

It looks like libgtk-3-dev should be used to build wxPython on Ubuntu 20. I will try this and report whether the build succeeds.

After a long container build, the build of WAIL completes. There are errors at runtime, likely due to architecture (I'm on arm64), but that is a separate issue.
