This almost works. But there are some problems that you can read here (with fixes).
If you want to try it, I managed to make an APT repo just for this:
curl https://apt.ivmoreau.com/focal/nextspace/key | sudo apt-key add - echo "deb https://apt.ivmoreau.com/focal/nextspace /" | sudo tee -a /etc/apt/sources.list sudo apt update sudo apt install nextspace-*
Oh, and btw, the provided scripts on the repo didn't work. So I had to manually make every package. But I think that this can be further automated.
