After upgrade runc to 1.2.0-1, when trying to establish the VPN I got the error
ERROR creating tun device: Unix opening TUN device file: operation not permitted
I got this with two gluetun instances with Wireguard tunnel, one to mullvad and one to my server.
Downgrade runc to 1.1.15-1 solves the problem

@DrFr4nk Thanks for reporting this. I have exactly the same problem after updating my ArchLinux system. Downgrading runc-1.2.0-1 to runc-1.1.9-1 resolved it for me as well.
Is this urgent?
