Okeydoke. Just to note the Ubuntu 20.04 installation instructions are here:
https://afni.nimh.nih.gov/pub/dist/doc/htmldoc/background_install/install_instructs/steps_linux_ubuntu20.html

For the GSL, I would run this to install it:

sudo apt-get install gsl

... and then this to link it (sigh):

sudo ln -s /usr/lib/x86_64-linux-gnu/libgsl.so.23 /usr/lib/x86_64-linux-gnu/libgsl.so.19

For Matplotlib, I would make sure Python 3 is there, and say numpy, but oddly the default installation version number of Matplotlib on Ubuntu 20.04 is quite old (less than requisite v2.2.3), so it should be installed using pip:

# install Python and numpy, as well as pip, and have "python" be recognized as a command, not just "python3"
sudo apt-get install -y python3-numpy python-is-python3 pip
# remove that matplotlib from aptitude, if it was installed
sudo apt-get remove  -y python3-matplotlib

# now, note that sudo should *not* be used here:
pip install matplotlib

You can verify your Matplotlib versions with:

python -c "import matplotlib; print(matplotlib.__version__)"

... which should be >=2.2.3.

And these "Please fix" items are pretty straightforward:

cp /software/afni_23_1_02/abin//AFNI.afnirc ~/.afnirc
suma -update_env
apsearch -update_all_afni_help

After that, you can check "afni_system_check.py -check_all" again, to verify that those issues have been happily resolved.
