Briefer command fails to pull docker images

[icarito]

Hi, when running briefer for the first time I got errors:

Downloading image briefercloud/briefer:latest...
Error: underlying stream is not seekable
Traceback (most recent call last):

io.UnsupportedOperation: underlying stream is not seekable

I was able to get past them with redirecting the output of the briefer command to a logfile (e.g. briefer > init.log)

I'm running it on Manjaro (Archlinux derivative).
Tried it both and failed both with bash and zsh.
