几年来，我一直在尝试使用 Landscape 来管理 Ubuntu 桌面。问题接踵而至。最新的问题是 Landscape 留下了对其自身的源列表引用。
示例输出。

有人遇到过这个问题吗？你是如何解决的？
答案1
正如评论中提到的，该软件包已损坏。更具体地说，软件包aait-geue-employee-vpn或软件包aait-geue-cert-renew已损坏。原因是两个软件包都试图修改同一个文件，这是 apt 所不允许的（否则，您可能会根据安装顺序获得不同的结果）。
作为用户，您可以执行以下操作：
- 向软件包维护者报告他们制作了一个损坏的软件包以便他们重建它；或者
- 在安装另一个包之前删除其中一个包，这样它们就不会同时安装。
作为软件包维护者你应该做的是：
- 如果两个包中的文件相同，则将其移动到一个
aait-geue-common包中，并向Depends: aait-geue-common两个包中添加依赖于它的控制文件。 - 如果文件相同并且您不想创建额外的包，请
Depends在一个包控制文件中添加一个并从该文件包中删除。 - 如果文件不同且应覆盖旧文件，请使用较新的软件包控制文件中
BreaksReplaces的 或Conflicts来确保安装该软件包会删除另一个软件包。它还明确指出两个软件包不能同时安装。
