[Errno 2] No such file or directory when running "pip list --format=freeze" in quick-install

[Savasci]

Hardware: Raspberry Pi 4 Model B Rev 1.1, Revision a03111 OS: Raspberry Pi OS (32-bit) Lite, up to date

Linux raspberrypi 5.4.51-v7l+ #1327 SMP Thu Jul 23 11:04:39 BST 2020 armv7l GNU/Linux

Somehow the quick-install fails with fatal: [localhost]: FAILED! => {"changed": false, "cmd": "/opt/tinypilot/venv/bin/pip list --format=freeze", "msg": "[Errno 2] No such file or directory", "rc": 2}

I suspect ansible failing already:

Thanks for reporting this!

The bdist_wheel failure is normal on the Pi.

That's strange that it's dying on that step. Can you try re-running the command? Everything in the install script is idempotent, so it's fine to re-run it.

Thank you for having a look! I ran this a few times to check if this is one of the limiting steps and it seems it is. Line 5 of the gist shows, that this was one of my later re-reruns, the error stays the same.

I've started from scratch now to see if one of the package updates is causing this issue, I'm restarting from a clean 2020-05-27-raspios-buster-lite-armhf.img to check.

Ok, so, on Linux raspberrypi 4.19.118-v7l+ #1311 SMP Mon Apr 27 14:26:42 BST 2020 armv7l GNU/Linux the quick-setup works without issues, the bdist_wheel failure still being present, as you said. My final stage on a clean a clean 2020-05-27-raspios-buster-lite-armhf:

apt-get upgrade is about to upgrade the following packages: ca-certificates firmware-atheros firmware-brcm80211 firmware-libertas firmware-misc-nonfree firmware-realtek libgnutls30 libraspberrypi-bin libraspberrypi-dev libraspberrypi-doc libraspberrypi0 raspberrypi-bootloader raspberrypi-kernel raspi-config rpi-eeprom rpi-eeprom-images from which at least one of them seems to brick the quick-install.

Hmm, that's strange. I'll try to repro on my side, but let me know if you discover anything more about why it's falling over on the virtualenv step.

[Savasci]

Thanks! Sure, I'll add if I find out, why that one happens.

Ah, upgrading after installing via quick-install works fine, currently running on Linux raspberrypi 5.4.51-v7l+ #1327 SMP Thu Jul 23 11:04:39 BST 2020 armv7l GNU/Linux
