_pygit2.GitError: error loading known_hosts

[jamesbernardi]

Since upgrading to 1.12.0 this has been a recurring error with Salt Stack 3005

_pygit2.GitError: error loading known_hosts

Rolling back to v 1.11.1 fixes this issue

[wwimberly]

Ran into the same issue in 1.12.0 for salt 3006.0. Downgrading to 1.11.1 made things happy.

Can you try with 1.12.2 ? There we bundle libssh2 1.11.0 which apparently fixes some compatibility issues with OpenSSL 3.0

I'm seeing the same behavior with pygit 1.12.2.

This is a problem with Salt's custom python environment. Using pygit2 1.12.0 in any other environment, including with Salt, works fine. https://github.com/saltstack/salt/issues/64345

Since 1.13 this now happens without Salt's custom python.

Is there a change that causes HOME to be determined at package load time? That is what I've observed.

Wat this not fixed in 3006.3?
