Description tastytea 2020-05-09 02:50:55 UTC

/lib/netifrc/net/wireguard.sh uses /usr/bin/wg, installed by net-vpn/wireguard-tools. wireguard.sh should check if wg exists and report an error if not.

Reproducible: Always

Steps to Reproduce:
1. Configure wireguard interface
2. Uninstall net-vpn/wireguard-tools
3. Start wireguard interface
Actual Results:  
Error message: “interface wg0 does not exist”.
If the user adds the interface with `ip link add wg0 type wireguard`, the init script seems to start fine but ping reports “Required key not available”.

Expected Results:  
An error message that says that wg couldn't be found and that it can be installed  from net-vpn/wireguard-tools.

You should get a message:
Skipping module wireguard due to missing program: wg

Can you please capture the full output, as I don't why this doesn't happen for your case.

$ rc-service net.wg0 stop
$ mv /usr/bin/wg{,_}
$ rc-service net.wg0 start
 * Bringing up interface wg0
Cannot find device "wg0"
 *   ERROR: interface wg0 does not exist
