Finally  After the purchase a newer machine Armory is running but it is online

Unbuntu 18.4
I use an external drive for both bitcoin and Armory folders although the apps are installed on the desktop.
I am manually running bitcoin-qt   (happy to change if you suggest.)
In Armory settings (GUI) I was able to point to the bitcoin blocks database on the external drive.
I was unable to point to armory databases to the external drive from the GUI so I attempt to do it with the terminal command.

armory --datadir="/media/bob/Backup Plus/Armory"

Things I have checked.
Bitcoin core is up to date and synced.
Bitcoin core is not pruning.
Current version of Armory is running.

Armory log.

Let me know if you have any ideas?
