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

Export

Fixes wg-quick failing because the config file does not exist at the expected path. Use when wg-quick names a .conf that was never created, often on a fresh install. Covers creating the config with Interface and Peer sections and correct permissions. Not for syntax errors inside an existing file.

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

TL;DR: there is no config file where wg-quick expects one. Create /etc/wireguard/wg0.conf with Interface and Peer sections, set permissions to 600, then run wg-quick up wg0 again.

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

Steps

  1. Create the config file:
sudo nano /etc/wireguard/wg0.conf
  1. Fill in Interface and Peer sections:
[Interface]
PrivateKey [your private key value]
Address = CONTAINER_IP/24

[Peer]
PublicKey [the peer public key value]
AllowedIPs = CONTAINER_IP/24
Endpoint = vpn.example.com:51820
  1. Lock down permissions (WireGuard refuses world-readable key files):
sudo chmod 600 /etc/wireguard/wg0.conf
  1. Bring it up:
sudo wg-quick up wg0

Expected: the interface comes up; wg show lists the peer.

When this applies

  • fresh installs where only the tools were installed, no config written
  • the interface name in the command does not match any file in /etc/wireguard
  • configs stored elsewhere and never copied into place

When it doesnt

  • the file exists but wg-quick complains about its contents — that is a syntax or key error
  • wg-quick: 'wg0' already exists — the opposite problem
  • permission denied reading the file — check ownership, not existence

Compatibility

wireguard-tools wg-quick on Linux.

Other phrasings

  • wg-quick config file not found
  • /etc/wireguard/wg0.conf: No such file or directory

Why it happens

wg-quick maps the interface name directly to a file path: up wg0 reads /etc/wireguard/wg0.conf. No file, no tunnel. Package installs ship the tools but never your config.

Edge cases

  • Use wg-quick up ./myconfig.conf... actually wg-quick accepts a full path, so configs can live elsewhere if you pass the path.
  • Keep keys out of version control; 600 permissions are the minimum.
