Unable to init server: Could not connect: Connection refused

Hello guys! I would like to report a problem that arose after updating my Linux distribution. When I start gufw from the command line I get the error messages below:

========================================================================

I am using version 19.10 compiled from the packages made available by you at https://launchpad.net/gui-ufw. In consultation on the page I saw that they posted a bug referring to the same error I'm seeing when trying to open the GUFW graphical interface, but there is still no answer to the error found. I believe that the same error occurs with version 20.04, I will install it later and test it.

Hi, Please, try this one: http://mirrors.kernel.org/ubuntu/pool/universe/g/gui-ufw/gufw_20.10.0-0ubuntu1_all.deb Best regards.
