I assume this pulled in some unrelated packages. As you do not mention any 
output, I assume there was no error.

One reason for what you see could be that you have previously compiled and 
installed curl from source (which will also build and install libcurl), and 
this local installation does not have ssl support.

One check that I can think of is to run

$ which curl

which returns

/usr/bin/curl

if you only have the Ubuntu package installed.

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,
