This is the relevant error, not pip.
You actually need rust since recent cryptography version, which I assume was bumped in this release.
Hello,
curl --proto ‘=https’ --tlsv1.2 -sSf https://sh.rustup.rs | sh
and also
sudo apt -y install rustc
work for me!!

Same issue here in venv.
Fixed it by installing the Rust compiler:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Next try to upgrade HA again. Installing cryptography takes a while so don’t worry about that…

Thanks! The curl pipeline worked for me, but I found that when I ran it as root, it only installed it for the root user, so I had to run it as the homeassistant user to make it available to HA.

… and a small wrinkle that confused me. That curl install step asks what you want to do, with:
- Proceed with installation (default)
- Customize installation
- Cancel installation
I typed “1”, and pressed enter (without the quotes). Seems that doesn’t match any of the choices, it cancels the installation. I assume I should have put “1)”, but to proceed from there, can just press enter.
This resolved it for me.
seems maybe an add-in/plug-in that those of us who have this problem are using needs to have its dependencies updated.

I don’t have time now to do anything more than this but maybe this helps for someone getting a more proper fix
It is enough to install rust with standard freebsd package manager: pkg install rust. All works ok afterwards.
On my old hassbian installation on my Raspberry PI4B I used:
sudo apt install rustc
This fixed my update to 2021.10.2 errors.
thanks guys, fixed it with sudo apt install rustc

I also had the same issue. Then I did: sudo apt install rustc. That went well. Then I tried to update HA again, but got this:

If you are seeing a compilation error please try the following steps to
successfully install cryptography:
1) Upgrade to the latest pip and try again. This will fix errors for most
users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
2) Read https://cryptography.io/en/latest/installation.html for specific
instructions for your platform.
3) Check our frequently asked questions for more information:
https://cryptography.io/en/latest/faq.html
4) Ensure you have a recent Rust toolchain installed:
https://cryptography.io/en/latest/installation.html#rust
5) If you are experiencing issues with Rust for *this release only* you may
set the environment variable `CRYPTOGRAPHY_DONT_BUILD_RUST=1`.

So what can I do now?
I did this first:
export CRYPTOGRAPHY_DONT_BUILD_RUST=1
then did the upgrade and it worked.

How do I do this in a venv? It’s asking for a password for the user “homeassistant”.
I am having the same problem. I changed the password but still asking for a password.
Worked for me thanks for the help.
you should install homeassistant as user pi instead of a new homeassistant user. i really don’t understand why the official guide advice for creating extra headaches for users. makes it a hell to edit the config yaml or do anything really if you’re not the default user
I am using HA in venv. Since a few weeks I got the error failed building wheel for cryptography homeassistant error when I trying to update.
I changed with sudo -u homeassistant -H -s to the homeassistant user and then set the variable
export CRYPTOGRAPHY_DONT_BUILD_RUST=1
Update worked!
Many, many thanks to @wciinet !!
After I already had some other cryptography problems while upgrading to HA 2022.10, I came up with the problem described here while upgrading to 2022.11.1 .
@kimme1024’s command was the way to go as the rustc-versions in the official Raspbian buster repositories don’t contain the required version.
What I want to add to this thread as Radu and dantist only scratch on the surface is that the routine mentioned above only installs rustc in the current user (see some more info about that here). So when you run HA with its own user, your HA upgrade will still fail when you installed rustc while being logged in e.g. as the pi-user. So I ended up executing the rustc-install with the homeassistant-user. Took me a while to realize that, maybe I can speed up someones others upgrade with this hint
