Gufw

Launching gufw leads to an immediate crash

Asked by SP

Executing gufw from the command line leads to the below crash after entering in password into the authentication box. From searching it looks like python-gi python-gobject and net-tools are all installed (I reinstalled just to make sure it was clean as well as gufw and ufw). It seems I'm missing some package but I can't figure out what.

  File "/usr/share/gufw/gufw/gufw.py", line 30, in <module>
    gufw = Gufw(controler.get_frontend())

No joy - still getting the same error:

Best regards

As you probably suspected, ufw wasn't enabled or running - once I did that, everything is good again. I wish that instead of bombing out gufw would have output an error message that would have pointed the way. Regardless, thanks for the help!
