我有一个比我当前版本更新版本的 qgis 的 rpm。
在这个命令上：sudo rpm --upgrade qgis-2.18.2-4.fc26.i686.rpm，我收到错误：

执行此操作时sudo yum update qt-devel，我得到 Package 1:qt-devel-4.6.2-28.el6_5.x86_64 已安装且最新版本
我该如何解决这些问题？
答案1
您正在尝试在 64 位 RHEL 6 上安装为 i686（32 位 Intel）构建的 Fedora 26 软件包。由于它会引入很长的依赖项列表（正如您所见），这将不起作用，即使您确实启用了适当的 FC26 存储库。
最好的选择是尝试在 RHEL 6（或 CentOS 6）上从源 rpm 重建软件包。
