What I'm doing:\r\n1. In Ubuntu 20.04 running under Docker, I'm cloning the repository using `clone_from`.\r\n2. The directory that I'm cloning to is mounted under MacOS as follows:\r\n`docker run --rm --interactive -v $PWD:/work --user $(id -u):$(id -g) /bin/bash`\r\n3. Docker container is running with UID and GID of the MacOS\r\n\r\nI'm getting this error:\r\n```\r\nException in thread my-repository:\r\nTraceback (most recent call last):\r\n  File \"/usr/local/lib/python3.8/dist-packages/git/util.py\", line 941, in _obtain_lock_or_raise\r\n    fd = os.open(lock_file, flags, 0)\r\nPermissionError: [Errno 13] Permission denied: '/work/repo/my-repository.git/.git/config.lock'\r\n\r\nThe above exception was the direct cause of the following exception:\r\n\r\nTraceback (most recent call last):\r\n  File \"/usr/lib/python3.8/threading.py\", line 932, in _bootstrap_inner\r\n    self.run()\r\n  File \"/app/clone-tool.py\", line 124, in run\r\n    git.Repo.clone_from(self.git_url, repo_dir)\r\n  File \"/usr/local/lib/python3.8/dist-packages/git/repo/base.py\", line 1325, in clone_from\r\n    return cls._clone(\r\n  File \"/usr/local/lib/python3.8/dist-packages/git/repo/base.py\", line 1252, in _clone\r\n    with repo.remotes[0].config_writer as writer:\r\n  File \"/usr/local/lib/python3.8/dist-packages/git/remote.py\", line 1146, in config_writer\r\n    writer = self.repo.config_writer()\r\n  File \"/usr/local/lib/python3.8/dist-packages/git/repo/base.py\", line 604, in config_writer\r\n    return GitConfigParser(self._get_config_path(config_level), read_only=False, repo=self)\r\n  File \"/usr/local/lib/python3.8/dist-packages/git/config.py\", line 366, in __init__\r\n    self._acquire_lock()\r\n  File \"/usr/local/lib/python3.8/dist-packages/git/config.py\", line 385, in _acquire_lock\r\n    self._lock._obtain_lock()\r\n  File \"/usr/local/lib/python3.8/dist-packages/git/util.py\", line 951, in _obtain_lock\r\n    return self._obtain_lock_or_raise()\r\n  File \"/usr/local/lib/python3.8/dist-packages/git/util.py\", line 944, in _obtain_lock_or_raise\r\n    raise IOError(str(e)) from e\r\nOSError: [Errno 13] Permission denied: '/work/repo/my-repository.git/.git/config.lock'\r\n```\r\n\r\nThe `config.lock` file as listed under Ubuntu:\r\n```\r\n$ ls -la\r\nls: cannot access 'config.lock': No such file or directory\r\ntotal 144\r\ndrwxr-xr-x 14 501 dialout    448 Mar 24 13:42 .\r\ndrwxr-xr-x 18 501 dialout    576 Mar 24 13:42 ..\r\n-rw-r--r--  1 501 dialout     23 Mar 24 13:42 HEAD\r\ndrwxr-xr-x  2 501 dialout     64 Mar 24 13:42 branches\r\n-rw-r--r--  1 501 dialout    298 Mar 24 13:42 config\r\n-?????????  ? ?   ?            ?            ? config.lock\r\n-rw-r--r--  1 501 dialout     73 Mar 24 13:42 description\r\ndrwxr-xr-x 14 501 dialout    448 Mar 24 13:42 hooks\r\n-rw-r--r--  1 501 dialout 122075 Mar 24 13:42 index\r\ndrwxr-xr-x  3 501 dialout     96 Mar 24 13:42 info\r\ndrwxr-xr-x  4 501 dialout    128 Mar 24 13:42 logs\r\ndrwxr-xr-x  4 501 dialout    128 Mar 24 13:42 objects\r\n-rw-r--r--  1 501 dialout    114 Mar 24 13:42 packed-refs\r\ndrwxr-xr-x  5 501 dialout    160 Mar 24 13:42 refs\r\n```\r\n\r\nAlso listed under MacOS:\r\n```\r\n$ ls -la\r\ntotal 288\r\ndrwxr-xr-x  14 mmajchrzycki  staff     448 Mar 24 14:42 .\r\ndrwxr-xr-x  18 mmajchrzycki  staff     576 Mar 24 14:42 ..\r\n-rw-r--r--   1 mmajchrzycki  staff      23 Mar 24 14:42 HEAD\r\ndrwxr-xr-x   2 mmajchrzycki  staff      64 Mar 24 14:42 branches\r\n-rw-r--r--@  1 mmajchrzycki  staff     298 Mar 24 14:42 config\r\n----------   1 mmajchrzycki  staff       0 Mar 24 14:42 config.lock\r\n-rw-r--r--   1 mmajchrzycki  staff      73 Mar 24 14:42 description\r\ndrwxr-xr-x  14 mmajchrzycki  staff     448 Mar 24 14:42 hooks\r\n-rw-r--r--   1 mmajchrzycki  staff  122075 Mar 24 14:42 index\r\ndrwxr-xr-x   3 mmajchrzycki  staff      96 Mar 24 14:42 info\r\ndrwxr-xr-x   4 mmajchrzycki  staff     128 Mar 24 14:42 logs\r\ndrwxr-xr-x   4 mmajchrzycki  staff     128 Mar 24 14:42 objects\r\n-rw-r--r--   1 mmajchrzycki  staff     114 Mar 24 14:42 packed-refs\r\n```\r\n\r\nI will provide a minimum set-up (docker file and python script) to reproduce it later.\r\n","author":{"url":"https://github.com/mmajchrzycki","@type":"Person","name":"mmajchrzycki"},"datePublished":"2023-03-24T14:11:33.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":9},"url":"https://github.com/1566/GitPython/issues/1566"}
