Hm... The conditions in that issue are different (my /proc is not mounted
with a hidepid option) but yes, the docker error message looks similar.

Failed to connect to bus: No such file or directory
When I run it again with strace, I see this system call failing:
connect(3, {sa_family=AF_UNIX, sun_path="/run/user/[UID]/bus"}, 21) = -1
ENOENT (No such file or directory)
The /run/user/[UID]/ directory does exist, both for the current user and
other users, but they do not contain a file named "bus". Perhaps because
this is a headless server with no desktop sessions at all?

I'm afraid I cannot. The policy for this machine is only to run binaries
from debian or built locally.
However, if runc assumes the presence of /run/user/$uid/bus, that does seem
likely to be a problem, does it not?
