can't find config-gfarm.none when first running config-gfarm

[WGandy]

When installing on Linux Mint (ubuntu 20.4) from the apt packages, I found that this file appears to be missing. I think I worked around it by simply creating an empty file called config-gfarm.none in the folder it was complaining about.

apt install gfmd
apt install gfsd
apt install gfarm-client gfarm-doc
config-gfarm -t
/usr/bin/config-gfarm: 90: .: Can't open /usr/share/gfarm/config/config-gfarm.none

After
touch /usr/share/gfarm/config/config-gfarm.none
I was able to see a result from config-gfarm -t. But, there were two warnings printed at the bottom:

WARNING: command not found: pg_ctl WARNING: command not found: psql

I'm not sure if this is related to the first issue or not.
