I am running version 0.79.3 on Ubuntu 16.04 (Odroid XU4) and after upgrading to HASS.io lastest version I am not able to install any additional add-ons.
Once I click on install it flashes red and nothing happens. I tested with several add-ons and behavior is the same. The log output doesn’t help as can be seen bellow:

where 10.0.0.116 is my computer’s IP from where I am accessing HASS.io.
Any tips on how to troubleshoot this?
