Fednode install full master

trying to run a counterparty server so I can get my coins back from an armory cold storage address.

Ubuntu 16.04, Bitcoin installed and synced, running through these instructions to install counterparty server https://counterparty.io/docs/federated_node/

Stuck at fednode install full master

Error is

logname: no login name
Traceback (most recent call last):
File “/usr/local/bin/fednode”, line 377, in
File “/usr/local/bin/fednode”, line 184, in main

SESSION_USER = subprocess.check_output(“logname”, shell=True).decode(“utf-8”).strip()

File “/usr/lib/python3.5/subprocess.py”, line 708, in run
output=stdout, stderr=stderr)
subprocess.CalledProcessError: Command ‘logname’ returned non-zero exit status 1

Any help would be great seeing as there is no other way I know of getting my tokens back from armory address???
