Paramiko无法访问私钥

Question

从Ubuntu 18.04发行版升级后。至20.04。

FileNotFoundError: [Errno 2] No such file or directory: '~/.ssh/id_rsa'
Exception in thread Thread-2:
Traceback (most recent call last):

    key = cls(filename=filename, password=password)

    self._from_private_key_file(filename, password)

  File "/home/cgi/.local/lib/python3.8/site-packages/paramiko/pkey.py", line 307, in _read_private_key_file
    with open(filename, "r") as f:

但是它在那里：

$ cat ~/.ssh/id_rsa
-----BEGIN RSA PRIVATE KEY-----
<no one is so stupid>

权限：

sudo$ ll /home/cgi/.ssh/id_rsa
-rw------- 1 cgi cgi 6363 Jul 29  2019 /home/cgi/.ssh/id_rsa

该脚本作为cgi的一部分在用户supervisord下运行。有什么帮助，为什么paramiko无法读取它？

**更新**

看起来我也无法直接从python3 shell中打开它

但是可以使用绝对路径：

完成

所以看起来~在python环境中没有被解释为我的用户（cgi）。

> os.path.expanduser("~")
< '/home/cgi'

但是我不能chdir或listdir它：

> os.listdir('~')
< FileNotFoundError: [Errno 2] No such file or directory: '~'

Answer 1

如@MartinPrikryl正确指出的，找不到~。 Here

在初始化paramiko连接之前执行这些命令：

os.environ["HOME"] = "/home/cgi/"
os.path.expanduser("~/.ssh/id_rsa")
