Ubuntu 22.04下Deja-dup因Duplicity崩溃报错“Could not understand duplicity version.”的解决求助

大家好，我目前在用Ubuntu 22.04系统，所有软件包都已经更新到最新版本了。最近用Deja-dup备份的时候碰到了个麻烦，直接弹出错误：Could not understand duplicity version.

我想着先排查下duplicity本身的问题，于是在终端里运行了duplicity --version，结果却出现了一堆报错信息，具体如下：

[xavier@imladris ~]$ duplicity --version

Traceback (most recent call last):

我已经试过重新安装python3-cryptography了，但问题还是没解决。有没有哪位朋友知道该怎么修复这个问题呀？万分感谢！
