[R-sig-Debian] Configure error: checking if libcurl supports https... no

[Michael Mahoney]

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.

Thanks,
