Ubuntu 20.04.2 焦点窝。
我的目标是通过 mk-build-deps 安装 KDE 调试符号。
为此，我创建了一个名为source-control以下内容的文本文件：

然后我已经跑了sudo mk-build-deps --install source-control
但是，我收到此错误：

运行dpkg -l | grep glib表明我已经安装了2.64.2-1ubuntu0.1版本glib-networking。
我不知道如何让它接受当前安装的版本作为正确版本。从我的文件内容可以看出，source-control我没有对版本设置任何限制，这意味着它们是由设置的mk-build-deps。我不知道它为什么决定要求版本2.64.1-1 @un uH，也不知道这是否是一个有效的版本。
答案1
问题不在于 mk-build-deps，而在于依赖项。
我所做的就是尝试使用文件apt install中的所有软件包source-control。这揭示了真正的问题：
glib-networking-dbgsym：依赖：glib-networking（= 2.64.1-1）但需要安装 2.64.2-1ubuntu0.1
发生这种情况是因为focal-updates有一个比 更新的版本focal，默认情况下使用 。所以我apt install glib-networking-services=2.64.1-1这样做了，这表明虽然glib-networking要降级，但这也将删除大量对 plasma-desktop 至关重要的软件包，所以我放弃了安装它的尝试。
幸运的是，在这种特定情况下，我设法减少了 Build-Dependencies 的数量，以至于所有需要安装的软件包都不会发生冲突。
