this is what I did just before the pip3 install command
export CRYPTOGRAPHY_DONT_BUILD_RUST=1
pip3 install --upgrade homeassistant

It works, thank you so much!
Cargo didn’t fix the problem but
export CRYPTOGRAPHY_DONT_BUILD_RUST=1
did the trick!!!

I’m trying to build Python 3.8.12 but I’m stuck with the cryptography build error, no way to get rid of it. I tried export, setting the value in .env, passing the var to the pip install command… No way! I don’t know where to look at, any hint is welcome. Thanks
I also get this error, when trying to upgrade to 2021.12.3. I have tried with
export CRYPTOGRAPHY_DONT_BUILD_RUST=1
but no luck. Also installing cargo does not help. Any ideas?

The export trick doesn’t work anymore in 2021.12, due to “cryptography” being bumped to 3.5.
That did the trick for me, i.e. installing a newer rust/cargo from origin.

Excellent, that worked. To clarify, these are the commands I ran:
sudo apt remove rustc
sudo curl https://sh.rustup.rs -sSf | sh
Thanks so much!

Hi,
for armv7 during the cargo and rustc installation
curl https://sh.rustup.rs -sSf | sh
please first select option 2 and chage it to “armv7-unknown-linux-gnueabihf”, rest just enter defaults and then select option 1 and install. After that type:
source $HOME/.cargo/env
To double check if it is ok, just type
rustc – version
to see if it is OK.
Then run again installation of HA and the Cryptography should be properly built.
Good luck 
P.S. be sure to unistall previous version via:
sudo apt remove rustc cargo
If you need to unistall previous cargo and rustc, use:
rustup self uninstall

Hi,
I found a workaround on one the debian bug reports. I seams to be a second bug with rust and git. If I set the following variables I was able to install the required cryptography 35.0.0 package:
export CRYPTOGRAPHY_DONT_BUILD_RUST=1
export CARGO_NET_GIT_FETCH_WITH_CLI=true

Hi, should I update Rust in pip env or in my main account? I updated as a root user but in pip env HA says me: error: can’t find Rust compiler
EDIT
Helped me adding
export PATH=$PATH:~/.cargo/bin
after instalation of Rush from
curl [https://sh.rustup.rs](https://sh.rustup.rs/) -sSf | sh
This did it for me! Running
rustup self uninstall
first was important.
I’m on a raspberry pi. To make sure I was on an ARMv7 processor architecture I ran:
cat /proc/cpuinfo

yet another similar, but slightly different issue:
cryptography==35 on a Pi 3b, with Rust installed via rustup, the command rustc -vV states that my platform is armv7-unknown-linux-gnueabihf – however, cryptography wants to use arm-unknown-linux-gnueabihf, which must be installed separately.
I used:
- install rust locally via rustup, and make sure it’s on the path
rustup target add arm-unknown-linux-gnueabihf- Incidentally, I am also using a system with two python versions installed, and needed to
export PYO3_CROSS_PYTHON_VERSION=3.8
…this finally worked.

Hi, new version HA and still the same:
error: can’t find Rust compiler
I’ve instaled from curl https://sh.rustup.rs -sSf | sh, set source $HOME/.cargo/env
and nothing change. Why with each a new version of HA is the same problem?
same here! everyone has a hint how to do but what is the official straightforward way to upgrade to 2022.11.xx?
solution can’t be so tricky 
same here! 2022.11.2
On RPi 4 (Raspbian GNU/Linux 11 (bullseye)) :
sudo apt install rustc
And then
pip install --upgrade pip (if not already done)
pip install --upgrade homeassistant
It worked for me (be careful, it’s very long…)

is this done with the pi login or where?
this does not work On RPi 4 (Raspbian GNU/Linux 11 (bullseye)) :
sudo apt install rustc
And then
pip install --upgrade pip (if not already done)
pip install --upgrade homeassistant
It worked for me (be careful, it’s very long…)
I try to give step by step instructions never could figure out why people have to be so cryptic on the steps they used to make something work
if this works 
you can sudo apt install rustc as any user, but the pip stuff you have to do inside your home assistant virtual environment if you are a core guy
