ERROR: Failed building wheel for cryptography

[koying (Chris B)]

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.

Can't update HA to the latest version

I also experienced this issue when trying to upgrade hass core, however when trying to install cargo I got an error of E: Package 'cargo' has no installation candidate to solve this I did the following: sudo apt remove rustc curl https://sh.rustup.rs -sSf | sh This installed rust and cargo on my Rpi4 running RaspberryPi 10 (Buster). Just leaving this here for anyone else that encounters the issue on Raspian. Make sure to run the curl command as the user who is running home-assistant.

[Rudhan (Tomas Rudh)]

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!

[seventh (Dima)]

Same problem even after upgrade rust. My log.
rustc 1.57.0

[Martor (Martin)]

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

[mike3]

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

[eode]

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.

[Piotr_Kowalski]

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?

[00lex (lex)]

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

[msly]

same here! 2022.11.2

[snigit]

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…)

[trentjw (Trenton J Wilson)]

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…)

[trentjw (Trenton J Wilson)]

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

[00lex (lex)]

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

[trentjw (Trenton J Wilson)]

That’s what I thought but it didn’t work this why I asked

[ThomasAtHome (Thomas Titze)]

Anyone find a solution for the cryptography problem? I tried to follow the recommendations in this thread, but no luck. I reinstalled rust and also tried to follow the description in Installation — Cryptography 39.0.0.dev1 documentation but still get the same error message:
Building wheel for cryptography (pyproject.toml) did not run successfully…
The cargo build seems to start, but at the end it fails here:

I’m on Raspberry 3 with HA Core. Do not understand why I have to compile this lib at all, is there a version which can be downloaded somewhere?

ERROR: Failed building wheel for cryptography

#install Rust

curl https://sh.rustup.rs -sSf | sh

sudo apt -y install rustc

pip3 install pyOpenSSL --upgrade

[ThomasAtHome (Thomas Titze)]

Thanks for the tip. Did the upgrade for pyOpenSSL

Successfully uninstalled pyOpenSSL-22.0.0
Successfully installed pyOpenSSL-22.1.0

But still the same error during upgrade of HA
Here is my HA environment reported from the build error

pip: n/a

rustc: n/a

Error is still
LLVM ERROR: Invalid abbrev number
error: could not compile `cryptography-rust

[Piotr_Kowalski]

After that I’ve installed a new version of HA

curl https://sh.rustup.rs  -sSf | sh
source $HOME/.cargo/env
