我按照 Fedora 26 安裝說明遇到了問題https://www.if-not-true-then-false.com/2010/install-virtualbox-with-yum-on-fedora-centos-red-hat-rhel/
在網頁的第 5 步中，該dnf install VirtualBox-5.2命令導致錯誤訊息，我已在本論壇查詢的末尾給出了該錯誤訊息。由於我不明白這些訊息的含義，因此我繼續執行步驟 5/usr/lib/virtualbox/vboxdrv.sh setup命令。該命令失敗；該/usr/lib/virtualbox/目錄確實不是現在存在。
我知道問題發生的原因，但我不知道如何解決。 幾個月前，我安裝了Fedora-Workstation-Live-x86_64-26-1.5.iso，然後手動執行dnf install @cinnamon-desktop，然後dnf install VirtualBox。當時我沒有執行任何其他操作虛擬盒安裝相關指令。 VirtualBox 沒有顯示在 cinnamon 啟動選單中，我隨後忘記了我已經安裝了它。 我請求幫助解決這個混亂的問題。

答案1
該VirtualBox-5.2軟體包不是您已安裝的現有軟體包的升級，因此您需要刪除後者：
sudo dnf remove VirtualBox VirtualBox-server
再次安裝之前VirtualBox-5.2。
答案2
檢查下載的 rpm 套件並使用 rpm -Uvh --replacefiles 安裝
