Paramiko 无法访问私钥 [英] Paramiko can not access private key

问题描述

从 Ubuntu 18.04 发行版升级后.到 20.04.

After a distribution upgrade from Ubuntu 18.04. to 20.04.

FileNotFoundError: [Errno 2] No such file or directory: '~/.ssh/id_rsa'
Exception in thread Thread-2:

  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:

但它就在那里:

$ 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

脚本在用户 cgi 下运行，作为 supervisord 的一部分.paramiko 无法读取的任何帮助?

The script is run under user cgi as part of a supervisord. Any help why paramiko can not read it?

** 更新 **

看来我也不能直接从python3 shell打开它

It looks like that I also can not open it from python3 shell directly

但是可以使用绝对路径:

所以看起来 ~ 在 python 环境中没有被解释为我的用户(cgi).

So it looks like the ~ is not interpreted as my user (cgi) within the python environment.

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

但我不能chdir或listdir它:

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

推荐答案

正如@MartinPrikryl 正确指出的那样，未找到 ~.这里

As @MartinPrikryl correctly pointed out, the ~ is not found. Here

在初始化 paramiko 连接之前执行这些命令:

Execute these commands before initalizing the paramiko connection:

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