wg-quick: `/etc/wireguard/wg0.conf' does not exist

Hi there,

I receive the following error on Fedora Linux:

wg-quick: `/etc/wireguard/wg0.conf' does not exist

It seems to be the line chmod 600 /etc/wireguard.

I fixed it through the following commands:

chmod 700 /etc/wireguard
chmod 600 /etc/wireguard/wg0.conf

Not 100% sure if this is safe, thus not a pull request. In my opinion it should also protect the private key in wg0.conf or is there a difference?

are you sure you didn't manually create that directory without +x by accident?

maybe it's a umask in your shell?

See line 212 of your script:

chmod 600 -R /etc/wireguard/

If I am not mistaken that sets 600 for everything? Should that maybe be replaced by:

chmod 700 /etc/wireguard
chmod 600 /etc/wireguard/*

I encountered the same issue after uninstalling WireGuard using the installation script and then attempting to reinstall it. What worked for me was:
1. Installing it as the root user.
2. Uninstalling it as the root user.
3. Reinstalling it as the superuser (though you could probably also install it as the root user, the installation instructions are a bit clearer for superuser).

Now, everything is working again. To avoid this problem in the future, I recommend always uninstalling WireGuard (if you’re using the script) as the root user rather than the superuser.
