Remote agent on Raspbian

[lkankowski]

Hi

---

Configuration

Operating system: Raspbian GNU/Linux 10 (buster) [fully updated]

PlatformIO Version (platformio --version): PlatformIO Core, version 5.1.0

Description of problem

It probably wont be the most descriptive report, but I just finished few hours fight with 'pio remote agent start' :)
Finally, after dozen times of reinstalling Platformio, installing pyenv and python 3.8.8, some additional packages (from bash history: cryptography==2.9, pyopenssl, cffi, pyopenssl) and lots of frustration with installing correct version of 'twisted' (finally I couldn't install other than 21.2) I did two successful steps:

1. change file platformio-core/platformio/package/manager/core.py:
   twisted_version = "19.10.0" if PY2 else "20.3.0" result = [ "twisted >= %s" % twisted_version, ]
   ('twisted ==...' into 'twisted >=...')
2. run command: CRYPTOGRAPHY_DONT_BUILD_RUST=1 pio remote agent

and it built.

Steps to Reproduce

as above

Actual Results

Expected Results

Additional info

YOU DO GREAT JOB WITH PLATFORMIO!

[ivankravets]

You just need these packages in your OS

sudo apt install python3-dev libffi-dev libssl-dev

The only you start pio remote agent start, PlatformIO Core will build dependencies on your machine.

I've tried on almost clean RPI4, and doesn't work :(

      =============================DEBUG ASSISTANCE=============================
      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`.

============================================================

An unexpected error occurred. Further steps:

* Verify that you have the latest version of PlatformIO using
  `pip install -U platformio` command

* Try to find answer in FAQ Troubleshooting section
  https://docs.platformio.org/page/faq.html

* Report this problem to the developers

[ivankravets]

It seems the cryptography package changed his installation process. See https://cryptography.io/en/latest/faq.html#installing-cryptography-fails-with-error-can-not-find-rust-compiler

Could you try to install apt install rustup?

[lkankowski]

There is no "rustup" in "Raspbian GNU/Linux 10 (buster)" repositories.
Sometimes, but not always, if I run for first time:
CRYPTOGRAPHY_DONT_BUILD_RUST=1 pio remote agent start
then compilation finishes with errors (unfortunately I didn't capture them).
And then second run pio remote agent start works.

[ivankravets]

Could you run pio upgrade --dev? Does it work now? You don't need to add manually CRYPTOGRAPHY_DONT_BUILD_RUST, it's already in the code.

[lkankowski]

Unfortunately, following error:

pi@rpi4:~ $ pio upgrade --dev
Please wait while upgrading PlatformIO ...
PlatformIO has been successfully upgraded to 5.1.1b1
Release notes: https://docs.platformio.org/en/latest/history.html
pi@rpi4:~ $ pio remote agent start

PlatformIO has been successfully upgraded to 5.1.1b1!

      =============================DEBUG ASSISTANCE=============================
      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`.

============================================================

An unexpected error occurred. Further steps:

* Verify that you have the latest version of PlatformIO using
  `pip install -U platformio` command

* Try to find answer in FAQ Troubleshooting section
  https://docs.platformio.org/page/faq.html

* Report this problem to the developers
  https://github.com/platformio/platformio-core/issues

============================================================

Same error after installing Rust compiler with command curl https://sh.rustup.rs -sSf | sh and with command CRYPTOGRAPHY_DONT_BUILD_RUST=1 pio remote agent start.
I can try this on completly clean Raspbian, but you must wait a few days.

      =============================DEBUG ASSISTANCE=============================
      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`.
      =============================DEBUG ASSISTANCE=============================

  error: can't find Rust compiler

  If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.

  To update pip, run:

      pip install --upgrade pip

  and then retry package installation.

  If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.

  This package requires Rust >=1.41.0.

      =============================DEBUG ASSISTANCE=============================
      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`.

============================================================

An unexpected error occurred. Further steps:

* Verify that you have the latest version of PlatformIO using
  `pip install -U platformio` command

* Try to find answer in FAQ Troubleshooting section
  https://docs.platformio.org/page/faq.html

* Report this problem to the developers
  https://github.com/platformio/platformio-core/issues

You need to have the next dependent packages:

sudo apt install python3-dev libssl-dev libffi-dev

Could you try to install the packages above and restart PlatformIO Remote agent?
