Downloaded the TAR and dragged the binary to the desktop. Double clicking did nothing.
Launching from terminal with ./networx gave the error: Failed to load module "canberra-gtk-module"
Add the dependency: sudo apt install libcanberra-gtk-module libcanberra-gtk3-module
Now no error on launching networx but nothing happens.
I read somewhere that 32 bit apps need the 32 bit version canberra so: sudo apt-get install libcanberra-gtk-module:i386
Again running ./networx does nothing. The process exists however. And double clicking the file on the desktop also gives the same result: a zombie process without any interface appearing.
