Hello

I'm running ubuntu 20.04.
I followed the instruction on your web site.
But when I get to the step:
rPkgsInstall -pkgs ALL
There were many error messages.

The output to
afni_system_check.py -check_all
is:

========================= summary, please fix: =========================
* just be aware: login shell 'bash', but our code examples use 'tcsh'
* AFNI programs show FAILURE
* missing R packages (see rPkgsInstall)
* insufficient data for AFNI bootcamp


Could you please help?
