Hi! thanks for this tool, it is the missing piece of my "post-modern python" toolset 😉

Thanks for the report! Could you show me the log at ~/.cache/prek.log or try running prek auto-update -vvv again?

[j178]

I tried but it succeed on my side, I suspect it might be a network issue:

I've disabled the corporate firewall/ssl proxy (WSS) to make sure it wasn't a certificate validation issue.

I tried to perform the steps manually for the ruff hook, and at the first try of the checkout I got the following:

> git checkout v0.12.11 -- .pre-commit-hooks.yaml
remote: Enumerating objects: 1, done.
remote: Counting objects: 100% (1/1), done.
remote: Total 1 (delta 0), reused 0 (delta 0), pack-reused 0 (from 0)
Receiving objects: 100% (1/1), 294 bytes | 294.00 KiB/s, done.
error: unable to read sha1 file of .pre-commit-hooks.yaml (4d17023022feb0d8fb8a8093fc3deb68feeab8fa)

at the second try it correctly checked out the file.
Not sure if this is the cause of the error, and if it's something in my setup or what else.

[j178]

This should be same issue as pre-commit/pre-commit#2865

@sanzoghenzo Hi, can you try to download the assets for your platform from https://github.com/j178/prek/actions/runs/17431257887?pr=617 and check if it fixes the issue?

[sanzoghenzo]

That was it! I can confirm that the version from the CI assets works.

Thank you so much @j178 for the lightning fast solution!
