Incompatibility with python-voluptuous 0.14.2

[rubdos]

The problem

I received an update on Arch Linux to python-voluptuous 0.14.2, which yields this error:

The error goes away after downgrading said package to 0.14.1.

Additional information

voluptuous changelog: https://github.com/alecthomas/voluptuous/releases/tag/0.14.2

These caught my attention:

• https://github.com/alecthomas/voluptuous/pull/499: support: drop support for python 3.7
• https://github.com/alecthomas/voluptuous/pull/501: support: run tests on python 3.11
• https://github.com/alecthomas/voluptuous/pull/502: support: run tests on python 3.12

Since iteritems() might be something from a backwards compatible age, that's why it caught my eye. But I'm furthermore clueless here.

@rubdos got the same problem, so I reinstalled previous version of voluptuous: python -m pip install --force-reinstall -v "voluptuous==0.13.1"

Seems to work out just fine

[rubdos]

@Baldhor downgrading with pacman -U /var/cache/pacman/pkg/python-voluptuous-0.14.1-1-any.pkg.tar.zst worked fine for me too, but partial upgrades are notoriously unsupported on Arch. I'd rather not have my OS eat my cat! :-)

[zeirix]

Same here with Manjaro Release 23.1.3. The latest voluptuous version from the Arch repo is 0.14.2-1. Sadly, I've flushed my pkg chache for the quick repair...

[leander091]

This should be fixed on the next release. This commit will fix it

[rubdos]

This should be fixed on the next release. This commit will fix it

@zeirix That would mean that the next workaround for Arch is to use esphome-dev from the AUR :-)

[zeirix]

Thank you so much! I fixed it in the /usr/lib/python3.11/site-packages/esphome/voluptuous_schema.py directly and it works! Trying to install esphome-dev ended with some dependency trouble.

[rubdos]

Trying to install esphome-dev ended with some dependency trouble.

Removing esphome and platformio-core first should handle that. There's currently a comment on the AUR to ask set Provides = platformio-core on platformio-git, but that has not been pushed yet.

pacman -R esphome platformio-core
paru eshome-dev platformio-git

or whatever favorite aur-helper you have around! :-)
