Updating Readynas install

Hi there, I had a readynas and there is a installation available for HA version 0.34
I have this working, but obviously I would like to keep this updated! The gui tells me an update is available, but nothing on the community web site instructions to upgrade works. I’ve tried $ pip3 install --upgrade homeassistant et al and I just get command not found.

Should I abandon homeassist as it’s not really for average users? Or have I missed an obvious way to upgrade? Readynas runs on debian (all the install apps are .deb), but I’m not familiar with unix as a casual user.

ReadyNAS was supported through a third-party but not updated in a while or the project is abandoned.

There is already an open issue.
