Forgive me if I'm missing something here, but do you need to install from source or do you just need R 4.1.0?
If the latter, my understanding is that you should be able to get R version 4.1.0 on Ubuntu distributions via: sudo apt install r-base=4.1.0-1.2004.0 r-recommended=4.1.0-1.2004.0 r-base-html=4.1.0-1.2004.0 r-doc-html=4.1.0-1.2004.0 Assuming you're using the official ppa (and uninstalled the newer versions first). If all you need is R 4.1.0, this might be a bit less temperamental.
