Ubuntu 17.04 after upgrade hass not starting

Installation
1

Any help appreciated.

I did a foolish thing and updated from Ubuntu 16.10 to 17.04, hass no longer works. I installed originally using the virtualenv. If i access the virtualenv and run a upgrade i get the following errors (I assume this is why it doesn’t start)

homeassistant@lando:~/.homeassistant$ source /srv/homeassistant/bin/activate
(homeassistant) homeassistant@lando:~/.homeassistant$ pip3 install --upgrade homeassistant

The command you are using is to install home assistant. Are you wanting to install or start home assistant?

sudo -u homeassistant -H /srv/homeassistant/bin/hass

should start HA if you followed the instructions above for installation.

same error when i try to run the start command (i tried the upgrade as i thought maybe ubuntu upgrade had damaged the installation)

tv@lando:~$ sudo -u homeassistant -H /srv/homeassistant/bin/hass

I haven’t tried on Ubuntu, but when upgrading Raspian to Stretch there was a new version of Python, so I had to recreate the Virtual Environment.

Just move the existing directory (/srv/homeassistant) and follow the instructions for installing from venv from the point of creating the venv directory.

thank you that fixed the issue.
