Could not read JSON repodata file parse error line 593230: subdir mismatch

[jwarwick-delfi]

What happened?

About an hour ago, we started to get these error messages in our CI build.

RuntimeError: Could not read JSON repodata file (/opt/micromamba/pkgs/cache/47929eba.json) parse error line 593230: subdir mismatch

It appears that we're not the only ones with that issue - I found it in the build logs in the coda-forge admin-migrations project.

Same here. You guys needs to address this asap that some packages have directory mismatch. Conda-forge is unusable right now.

[kenodegard]

we are aware of this issue

for the conda-forge specific status updates see conda-forge/status#144

[kenodegard]

Repodatas have been regenerated and the subdir mismatch is no longer present.

[kenodegard]

closing this since the immediate issue has been resolved

conda/conda-index#105 is a potential solution to detect this issue in the future
