So there's nothing you can do on the client-side to address the problem, you'll have to reach out to the admin of that repository and tell them that the repository uses an invalid value for "core.fsync". > I also tried git with different version (2.25.1 and 2.34.1) to clone the > repo, both will show this warning. What configuration causes this warning? It's "core.fsync" indeed, but not on your side. The config does not take a boolean, but rather a list of components that should use fsync. I guess the admin wanted to just fsync everything, but in that case you don't want "core.fsync=true" but "core.fsync=all". Patrick
