Rstudio installer for Ubuntu 20.04

RStudio IDE

I can install Rstudio desktop in my Ubuntu 20.04. Can anyone help me find an installer?
Repository's older version is for Ubuntu 22 and is not working. I get the next error:

You can find archived versions of RStudio here. I think 2024.12.1 might work for you.

That may or may not fix the error message, though. It appears you do not have libssl3 installed. It may be that the older version of RStudio will be looking for an older version of libssl; I don't recall. If you get the same error message with an older RStudio install, use Synaptic (or apt) to install the missing library.
