I recently upgraded my development server to Ubuntu 20.04, and am running WeBWorK 2.16.
Almost everything went smoothly, except that I am unable to install the Statistics::R::IO Perl module. All other modules installed without issue.
Has anyone else run into this? It's not a big issue on this server, because I don't need to run problems with R there.
But my production server will need it to work, so I am sticking to Ubuntu 16.04 until I figure out a solution.
What happens when you try to install the module? Do you get a specific error message?
Did you have rserve running when you tried the installation? The error messages aren't particularly descriptive as to what went wrong, but it looks like some of the tests are trying to run various commands, which I assume need an active rserve instance to connect to.
You can always try a force install. That has worked for me in the past for other perl packages. The problem is that you won't know if some aspect of the package is broken until an error appears.
Yes, I had Rserve running, and listening on port 6311.
The install tries to run a bunch of tests, all of which fail. Could give the force install a try.
I has this issue exactly, and has to installed the module manually.

Thank you, I will try this!
