Getting the same on just plain arch.

Modifying the PKGBUILD like advised by @intelfx (if I understood it correctly) helps and the build and installatio succeeeds. (haven't tested runtime yet)

@snowman78, try commenting out the conditional in build() that tests whether /var/run/docker.sock is available, such that the else branch is always taken.

Trying to install this on EndeavourOS using yay. It fails after a while, with this stuff:

Docker is running, docker.sock is owned by root and in group docker. My user is also in group docker, so I can run docker stuff. yay is run as my user, then if it needs it, it requests sudo. It didn't now, I think.
