I am running Vivado 18.3 on Ubuntu 18.04, and cannot connect to my Arty board. While troubleshooting, I found directions on installing cable drivers and board files (https://reference.digilentinc.com/vivado/installing-vivado/start), however I cannot find the path referenced in 2.1. I have an /opt directory, but it is empty, and while I can find a couple /data directories that look like they could be correct, none of them contain a xicom (or .xicom) directory.
Note: I installed Vivado a while back but never got around to playing with the board until now. I wanted to exhaust all options before trying a fresh install of Vivado.
SOLUTION UPDATE: I found the correct directory path by typing "which vivado" into the terminal, which pointed me to /tools/Xilinx/Vivado instead of /opt/Xilinx/Vivado
