在 Ubuntu 22.04 上使用 Duplicity 0.8.21，我可以备份到 S3 OK，但是当我尝试恢复时，我得到：
Traceback (innermost last):

TypeError: a bytes-like object is required, not 'str'
我认为这可能是代理问题，因为我认为这些错误是相关的：
ERROR Nov 16 15:42:27.589 [943713]: read_request_line: Client (file descriptor: 8) closed socket before read.
ERROR Nov 16 15:42:27.591 [943713]: Error reading readable client_fd 8
所以我把它（和出站防火墙）撤掉了，但是现在得到：

当我尝试使用运行完全相同设置的虚拟机进行恢复时，一切正常。有人知道发生了什么吗？这些看起来像是与网络相关的错误。我是否缺少某些模块或什么？
