Manually doing the rename works, so I do have the necessary permissions.

[CyberShadow]

The failure is coming from your filesystem, so look for the problem there.

Things I would check for:

• If it's a network filesystem (or host folder mounted in a VM), use a local filesystem instead.
• Stop any programs which could be intercepting filesystem operations (antivirus etc.)
• If you've previously ran things that might touch those paths as root (via sudo), reset permissions/ownership on those files recursively (or just delete them).
• Check for any sticky bits which might cause permissions to propagate to child filesystem objects.
• If you are trying to run Digger in an unusual environment (e.g. Windows Subsystem for Linux), try a more typical one (native Windows Digger executable or a full Linux VM).

From looking at the stack trace and the log you posted, I don't see how this can be due to Digger doing something wrong. If you can reproduce the issue reliably, we can try to narrow it down, but I would start with checking your environment as described above.

[John-Colvin]

Hmm, yes this problem does seem to be exclusive to WSL, but I can reproduce it on multiple WSL instances on different windows machines.

[CyberShadow]

Okay, thanks for letting me know. Unfortunately I'm not interested in spending time researching workarounds for WSL bugs. If this problem is important to you, I suggest narrowing it down to a simple test case, then filing a bug with Microsoft and/or submitting the workaround as a pull request to Digger / ae.
