Upgrading HASS venv from 0.91.4 to 0.92.2-Upgrade failed-Cryptography issue

Installation
1

Just attempted the above using my usual procedure and upgrade failed. This is the output of the upgrade log. The first time I tried the upgrade the log suggested upgrading pip version which I did correctly

You are using pip version 19.0.3, however version 19.1 is available.
You should consider upgrading via the ‘pip install --upgrade pip’ command.

After the second attempt upgrading heres the output relating to cryptography errors. Has anything changed in the last two weeks that might be causing this issue and what I could do to overcome it.

From research in another thread, try sudo apt-get install libssl-dev

Yes I tried that earlier after upgrading my version of pip. Not sure which worked but the upgrade proceeded as planned.

I took an iso image of the sd card so I’m going to try the upgrade without the pip upgrade and see if this works.

If so I’ll do a quick write up in copy/paste format for others to follow who are upgrading in the venv environment.

I tried to follow an earlier post with a number of different solutions but the “that works for me” responses are not actually saying which solution works.

Thanks for that!!!

The complaint about the version of pip is just because the latest is not packaged for that OS distribution. There is no harm in upgrading pip or not.

5

Yes the successful upgrade didn’t depend on a pip upgrade but I upgraded pip anyway.

Just to confirm what I needed to do was install sudo apt-get install libssl-dev in the home folder of Raspbian before proceeding with the upgrade.

@anon34565116 well spotted and that saved many hours of troubleshooting.

I just looked at the latest docs for manual install on a Raspberry Pi and they seem to have changed somewhat since I original did my first install.

A while back when I was running a venv when an upgrade broke, I found some documented z-wave dependencies I was missing all of a sudden.
We do not necessarily know when the documentation is updated and, at times, the documentation is not updated to match the current release. I think Devs are focusing more on the Docker & Hassio installs because they then have more control over the OS environment.

7

Am I correct in assuming that if I went the HassIO route I’d be restricted in what platforms I could add to my system.

I’ve just read back on the forum since the release of 0.92 and quite a few users have struggled upgrading similar to myself.

8

I am not sure I understand the question.
Hassio has some docker-based addons to make things easy but, as far as I know, any platform addon supported by Home Assistant should work in Hassio, especially since they are forcing custom components to have proper manifests…

9

I get this error too, and I did install the libssl-dev as my pi user (with sudo)
I followed some old instruction to install the venv on my RPi
The installation is made in the directory /srv/homeassistant
So I tried to rename that directory and the /home/homeassistant/.homeassistant
And then I tried to follow the same old venv doc and I get the same result with a this clean install.

I then moved the original directories back, and the HA starts up without any problem. But when I try to upgrade I get the following

So, the error clearly says libffi is missing.
What did you do to try & resolve that?

Not OP, but installing libffi-dev as described here (stackexchange) solved this error message when upgrading 0.91.3 to 0.93.2.

Thanks for pointing me in the right direction btw! I still find it hard to find the important part of long error messages
