Hi,
I’m using a repo to build App on HF, but when it runs it always report the following error:
```auto
Traceback (most recent call last):
File "/home/user/.local/lib/python3.8/site-packages/huggingface_hub/repository.py", line 742, in clone_from
run_subprocess("git lfs install", self.local_dir)

raise CalledProcessError(retcode, process.args,
subprocess.CalledProcessError: Command '['git', 'lfs', 'install']' returned non-zero exit status 2.
During handling of the above exception, another exception occurred:

OSError: Hook already exists: post-checkout
#!/bin/sh
command -v git-lfs >/dev/null 2>&1 || { echo >&2 "\nThis repository is configured for Git LFS but 'git-lfs' was not found on your path. If you no longer wish to use Git LFS, remove this hook by deleting '.git/hooks/post-checkout'.\n"; exit 2; }
git lfs post-checkout "$@"
To resolve this, either:
1: run `git lfs update --manual` for instructions on how to merge hooks.
2: run `git lfs update --force` to overwrite your hook.
```
Any idea on how to solve this?
Thx

No solution on this for now. I just use my own server instead of HF server to build the app.
