The command '/bin/ash -o pipefail -c sed -i -e 's/v[[:digit:]]..*//edge//g' /etc/apk/repositories && apk add --no-cache snapcast bash' returned a non-zero code: 1

What host OS are you running on?

Alpine Linux 3.13.0 requires the host Docker to be version 19.03.9 (which contains backported moby commit 89fabf0) or greater and the host libseccomp to be version 2.4.2.

Might need a backport of libseccomp or this might help:
