hi Mihai

thank you so much! the /usr/lib/x86_64-linux-gnu in the LD_LIBRARY_PATH
was indeed the culprit! after removing it, I am now able to log in all my
servers!

I checked my file modification history for .bashrc, I added this path for a
subset of my machines on March 11. It was also the window when I
applied the package updates throughout my cluster, so I mistook the
issue to the new packages. my bad!

once again, thank you for the insightful suggestions, and I am so happy
x2go works again!
