Unable to get gufw to run

Robert42 · 2016-10-26 20:17:00

Running Arch 64 bit with Cinnamon DE.

I have installed ufw as per the Wiki and modified the examples for my network. ufw status shows it is enabled and the rules are set.

I cannot get the front end gufw to run. It attempts to open by requesting authorisation and making the open sound. I have checked that all dependencies have been installed. Run from the command line here is the errors.

What command did you use to install it? Are you 100% sure this is an up-to-date system?

sudo pacman -Sy gufw

No errors during installation. I have just had a look in the AUR package page and it was last updated today.

Don't do that...

I read the link then to pacman wiki to double check. I uninstalled

sudo pacman -R gufw

and reinstalled

sudo pacman -Syu gufw

Still not behaving any better.

Did you read the article? Partial upgrades are unsupported. Try running

pacman -Syu

to bring your system to a consistent state. After that, don't install packages using the -y flag and always update by running the above command.

I have the same problem with identical error message on two different computers. Both systems are 100% up-to-date. Ufw status is active.

Do you have the net-tools package installed? It is not installed by default and contains the netstat program. The error indicates that gufw can't find netstat, so that's probably your fix. I would also file a bug report about the missing dependency if this turns out to be the problem.

The conversion to use netstat appears to be this change http://bazaar.launchpad.net/~costales/g … revision/5
This change may be more of an issue http://bazaar.launchpad.net/~costales/g … revision/6 as there is no '--all-ip-addresses' option to the hostname command as supplied by arch.

Finally got gufw working it is an unlisted dependency, you need to install net-tools package.

Did you raise the bug report?

I might be dumb but I spent over an hour tryng to get that page to work for me. Yes and I did read the wiki. Gave up in the end as I am sure someone else will do it.
