Cffi error stops upgrading on several Pi's

Mastiff · April 21, 2019, 10:00am

I have regular installs on seven Pi’s (not Docker because HA is integrated with other stuff on the Pi), and I tried to do an upgrade to the latest version. But they all say the same, can anybody help me out with what I need to do here? It says a lot of adding directories to a variable, but I think the whole thing should work automatic with the ```
pip3 install --upgrade homeassistant

Try apt-get install libffi-dev

It appears to me the devs are focusing on Docker & Hassio builds and Hassbian images. They can then control dependencies.

Mastiff · April 21, 2019, 12:11pm

Thanks! I didn’t get an error message this time! But the version is still 0.80.2. Should’nt it be higher? in my “Update Available” message it says 0.91.4.

Edit: The “Update Available” message dissappears after the update, even if it still says 0.80.2 as the version.

anon34565116 · April 21, 2019, 12:43pm

0.91.4 is the current version. Try a reboot?

Mastiff · April 21, 2019, 12:44pm

Right. So why isn’t HA showing that after the pip3 install --upgrade homeassistant

And this is on five different Pi’s! After restart of HA and everything.

anon34565116 · April 21, 2019, 12:48pm

Not showing or wrong version?
I am assuming you are in the Python venv when installing.

Mastiff · April 21, 2019, 1:03pm

It’s not showing the right version. And I have no idea what a venv is, I have just followed the instructions that came up when I clicked on the cloud showing the new version:

The default way to update Home Assistant to the latest release, when available, is:

$ pip3 install --upgrade homeassistant

Edit: Virtual environment, OK. DOes that mean I should run that as the homeassistant user, not pi? If that’s the case, I wish it had said so…

Edit 2: Is this where I do the Star Wars joke, “You assume too much”?

anon34565116 · April 21, 2019, 1:08pm

Here is the official way.

$ sudo -u homeassistant -H -s
$ source /srv/homeassistant/bin/activate
$ pip3 install --upgrade homeassistant

or now try

$ sudo -u homeassistant -H -s
$ source /srv/homeassistant/bin/activate
$ pip3 install homeassistant==0.91.4

Mastiff · April 21, 2019, 1:18pm

Thanks! This time it worked. Maybe that should have been linked in the page users get up when they click the cloud showing an update being ready. Also, is there a whole other installation somewhere now, with the commands I issued from outside the virtual environment, that I need to get rid of?

anon34565116 · April 21, 2019, 1:23pm

You could do pip3 uninstall homeassistant

Mastiff · April 21, 2019, 1:23pm

Great, thanks again!

AndreaF · April 26, 2019, 8:57am

I have the same problem as Mastiff… upgraded to .92 (via pip3) but it shows the old (.81) version instead. If I want to remove the not working upgrade and do it again is it correct to do pip3 uninstall homeassistant==0.92 and then a new upgrade as written above?

psfales · April 26, 2019, 2:19pm

Thanks for the info. Had the same problem when upgrading from 0.91.4, but " apt-get install libffi-dev" worked for me
