我仍然能够运行Anaconda，但是Python安装在意外地创建了一个错误的符号链接并试图升级Python版本之后遇到了一些问题。

既不能运行sudo dpkg --configure -a也不能运行sudo apt-get install -f

你的帖子在细节上有点薄弱(你到底做了些什么？)为什么要在描述中包括蟒蛇？但是，手动升级整个系统范围的python安装是个坏主意，因为许多系统实用程序依赖于正确的python版本。我强烈建议您恢复您的更改，如果需要更新的python版本，请构建一个python虚拟环境。。

尽管如此，我看到的唯一问题是，由于安装脚本中有一个意想不到的字符，无法安装单个包(01-ubuntu-drivers-common_1%3a0.8.6.3~0.18.04.1_amd64.deb)。我们确定这取决于python的升级吗？如果是，为什么？

请恢复您的python升级，然后重试。
