I downloaded FileZilla to my system, extracted it, yet I can’t figure out how to open it to get to the graphical interface to start using it.
I think you are going about it the wrong way
You should use the package system to install things
In Debian you can use
synaptic to install a package. I am not familiar with Ubuntu
sudo apt install filezilla
That should do it.
Hello and welcome.
I just fired up a virtual Ubuntu to look at the right way:
Hit the “Super-Key” (Windows-key), type “software”.
There should be “Ubuntu Software Center” in the results.
Doubleclick it and do a search (upper right corner) for “filezilla”.
The terminal is the shorter way though…
