我每天都会收到相同的 Ubuntu 基础版和 mesa 更新。我已经安装了这些更新 10 多次，但每天都会显示需要安装的相同更新。我不知道是什么导致了这个问题，同样我也不知道需要提供什么数据才能找到解决方案。

答案1
“Ubuntu Base” 实际上只是一个简称，它指的是很多库和程序。如果你展开它，你每次都会看到不同的库。
定期更新是正常的因为有错误修复和更新，无论是否安全，常见的每天展示并更新这些内容。
举个例子，你可以看到这里的许多“包”都是不同版本。您可以从字符串中看出：
Unpacking mesa-vulkan-drivers:amd64 (20.3~git2011070730.b7793e~oibaf~g) over (20.3~git2011061930.a0b42d~oibaf~g) ...
您正在使用 oibaf PPA/drivers 存储库，它需要每晚 git 快照来自上游存储库并发布新的软件包 - 因为您是从第三方存储库中提取这些软件包（参见此行Hit:9 http://ppa.launchpad.net/oibaf/graphics-drivers/ubuntu groovy InRelease：），所以您只能听从该存储库的摆布。
标准 Ubuntu 存储库不会每晚更新这些软件包。第三方软件包存储库（例如 OIBAF 存储库、图形驱动程序 PPA 和 WineHQ PPA）将总是以不同的周期和时间表提供更新，这样您总是会因为夜间构建而获得更新（这就是为什么您每天都会看到这些更新）。
