gufw won't work on my PC :-(

[hmiersch]

Hi.
I recently installed gufw on my PC (19.04, been using it for a while) but gufw REFUSES to work. When I launch it, I get the window asking me to enter the admin password which I do, and when I press return, that window disappears, and that's it. No gufw window, no error message, no nothing. I've checked out other forums, but so far nothing has convinced gufw to work. How can I make it work?

Weirdly enough, gufw works ok on my MacBook pro (also 19.04, new install). Hmm...

I had this problem, also. Post #6 in the following link fixed it on my machine. https://bugs.launchpad.net/ubuntu/+s...w/+bug/1592380

I found that page by running gufw from the command line and entering the last error output into a search engine:

/usr/bin/gufw-pkexec: line 13:  5115 Segmentation fault      (core dumped) python3 ${LOCATIONS[${i}]} $1

HTH

i did that, and gufw showed me its window. so far so good. but the next time i started up, the old problem was back. apparently this solution is NOT permanent. is there a way to make it permanent?

One solution is to put the following statement in ~/.bashrc

xhost +si:localuser:root > /dev/null

Don't know if there are any security implications though.

If you are logging in using Wayland, try switching to an Xorg session and see if the problem persists:

so, can anyone help me?

Open a terminal.
run
sudo -H gufw
Does it work? Always remember the -H option, otherwise, it can be bad.
If not, what are the errors show?
In the meantime, you can use ufw or iptables.
