Hello!
I try to run oxidized (0.27.0) on Ubuntu 18.04.3 LTS. Install it according to the official manual (GitHub - ytti/oxidized: Oxidized is a network device configuration backup tool. It's a RANCID replacement!). And configure to backup config from juniper MX via ssh-key. Generate key-pair, create a user on Juniper, add pub key to Juniper. Check ssh login under oxidized user to the device and all works fine.
Modify the oxidized config file:
username: diffs

Add “router.db” file and run oxidized and get error on ssh connection:
