我在 Ubuntu 论坛和 Steam 社区发布了同样的内容，但没有找到解决方案。
sudo apt update随后导致sudo apt upgrade以下内容：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Calculating upgrade... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies.
steam:i386 : Conflicts: steam-launcher but 1:1.0.0.64 is to be installed
Conflicts: steam-launcher:i386
steam-devices : Conflicts: steam-launcher but 1:1.0.0.64 is to be installed
Conflicts: steam-launcher:i386
E: Broken packages
我不知道这两者之间是否有联系，但软件更新程序运行得很好。
Steam 也会像往常一样在发布时进行更新。
当我运行时，sudo apt update我被告知有 22 个包需要升级，所以我希望找到解决方法。
我也跑过：
sudo apt-get install unattended-upgrades
sudo dpkg-reconfigure unattended-upgrades
但什么也没发生。
提前致谢。

我建议你更新你的存储库并修复未满足的依赖项。打开终端并运行：
nano /etc/apt/sources.list
用新存储库替换旧存储库并保存文件。然后运行：
sudo apt-get update
sudo apt-get install -f
sudo apt autoremove
sudo apt clean
更加重视你的存储库。祝你好运！
