I downloaded "doxygen-1.8.20.linux.bin.tar.gz" here:""
How to install it on Ubuntu 20.04?
21 Answer
This software is already packaged in the Ubuntu 20.04 LTS repository with modern and actual 1.8.17 version.
Simply open terminal and run
sudo apt-add-repository universe sudo apt-get update sudo apt-get install doxygen then use it as it was planned.
