软件更新神秘包

Ubuntu 18.04.3。

软件更新程序一直要求我安装软件包，但它没有提供有关软件包的信息。它只说有 706 kB 需要下载和安装。如果我点击“立即安装”，一切似乎都按照正常的安装过程进行，但它随后会将我带回到同一个窗口，说还有 706 kB 需要下载和安装。

我已附加我所见内容的屏幕截图。

它为什么会这样做？

我应该怎样修复此问题？

在此处输入图片描述

答案1

System76 PPA 实际上是问题的根源。我与 System76 进行了交谈。他们解释说，他们的 PPA 具有与 Ubuntu 存储库相同的软件包。但由于它们来自非 Ubuntu 存储库，因此 Ubuntu 将它们视为“降级”，即使它们是完全相同的版本。因此，我“安装”了“降级”，版本没有改变，奇怪的软件更新程序消息消失了，现在一切似乎都很好。
