Bunsen Labs is a Debian derivative:
https://www.bunsenlabs.org/.
This page deals with repositories:
https://pkg.bunsenlabs.org/.
With gksudo geany, I created the file: /etc/apt/sources.list.d/bunsen-jessie-backports.list
with this content:
Then I ran the command: sudo apt-get update && sudo apt-get upgrade in the terminal.
Then I ran the command: sudo apt-get install gedit. And the result was: Unable to locate package.
I even restarted the computer. But that didn't work either.
What am I doing wrong here?
