更新时出现损坏的软件包错误

更新 Ubuntu 20.04 时，出现以下错误：

Errors were encountered while processing:
 /var/cache/apt/archives/libsystemd0_245.4-4ubuntu3.2_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

该系统运行的是 19.10，最近升级到 20.04。

其结果sudo apt autoremove是：

You might want to run 'apt --fix-broken install' to correct these.

如果你在软件 sources.list 中添加了导致大量版本冲突的 PPA，请删除它们，然后使用以下命令恢复 Ubuntu 的默认软件存储库：如何恢复默认存储库？.然后使用 更新软件源sudo apt update。

删除生成错误消息的缓存 libsystemd0 .deb 文件并重新安装 libsystemd0 和 libudev1。

sudo rm /var/cache/apt/archives/libsystemd0_245.4-4ubuntu3.2_amd64.deb # If this command results in a warning ignore the warning.
sudo apt update # try to update again
sudo apt autoremove 
sudo apt remove libsystemd0:i386 libudev1:i386 libsystemd0 libudev1
sudo apt --fix-broken install 
sudo apt install libsystemd0 libudev1
