Looks like we need to set the default branch to verify; it's verifying something from master:

github.com/moby/moby/v2/daemon/libnetwork/internal/nftables
# [pkg-config --cflags  -- libnftables]
Package libnftables was not found in the pkg-config search path.
Perhaps you should add the directory containing `libnftables.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libnftables', required by 'virtual:world', not found
error: Bad exit status from

Probably this needs to be changed to 28.x (the branch) as default;

docker-ce-packaging/common.mk

Line 39 in 610ec2e

REF ?= HEAD

• [27.x] use upstream 27.x branch as default #1053
