ERROR MESSAGE, copied from terminal:
rstudio: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory
(The commands 'rstudio' and 'rstudio --run-diagnostics' both produce the same error.)
rdesktop.log is a blank file.
rsession-kevin.log is a blank file.
RStudio.Version() produces no message, just returns me to the prompt.
I have launched it in the past, but I haven't used rstudio in a couple years, mostly just running R from the terminal (which still works).
apt-get install libssl.so (and similar)
