由于缺少 python 包，从 12 升级到 14 失败，现在怎么办？

do-release-upgrade 在此过程中深度中止。

主日志文件以以下内容结尾。我该如何恢复此系统？（apt.log 文件看起来很无聊）。

我遇到了这个问题，并且从其他来源获得了一个有问题的 python-apt 包。我apt通过编辑/etc/apt/sources.list和删除文件手动删除了这些来源/etc/apt/sources.list.d，然后执行以下操作：

apt-get update 
apt-get remove python-apt
apt-get install update-manager-core

最后一个命令将重新安装 python-apt，它应该来自正确的 ubtuntu 源。升级现在似乎运行良好。
