Common issues #10

Create a file for instructors with common issues that we see happen with learners.

Here are some:

On Mac OS by default zip files downloaded from web are decompressed. This affects the file transfer lesson.
On VS Code some people's connection timed-out. Going to the Remote SSH extension settings and increasing the timeout to 60s solved this issue.

R packages not available

The libPaths variable is defined in ~/.Rprofile file. It has to be done this way, otherwise the compute nodes don't see it. But if the participant accidentally deletes the file (it happened once!), then the packages will not be available. The solution is to copy one of our ~/.Rprofile to their home. Or alternatively, they can run:

echo '.libPaths("/scratch/applications/R/site-library")' > ~/.Rprofile
