FWIW.
I had 4 Bionic installs that just had docker-ce installed from the repo
along with pip docker and this issue hit me. These hosts did not have
docker-compose installed. I just had to `apt -y remove golang-docker-
credential-helpers; pip install docker` to get it to work via command
line or
stumbled across this trying to debug my mount issues. Here is my strace
attempting a default mount from the command line. The same autofs setup
(auto.master, etc) work fine on SL 6.6 fwiw
strace -f -eexecve mount server:/export/ufs/hp /mnt
execve(/bin/mount, [mount, server:/export/ufs/hp, /mnt],
