Hi there, I also just ran into this issue yesterday. I installed `wireguard-tools` on a minimal Debian Buster system and `wg-quick` gave me the same error:
> wg-quick up wg0 > ... > > [#] resolvconf -a wg0 -m 0 -x > /usr/bin/wg-quick: line 32: resolvconf: command not found Is there a particular reason why `wireguard-tools` only "suggests" resolvconf but does not depend on it? >From my point of view, resolvconf should be a hard dependency. As mentioned before, installing the `resolvconf` package fixed the issue. Greetings, Jack
