我看到了兩個與我的問題類似的問題，但都沒有適合我的解決方案。當我嘗試從 Ubuntu 儲存庫安裝 VirtualBox 時，產生的程式給出錯誤：
VirtualBox: supR3HardenedMainGetTrustedMain: dlopen("/usr/lib/virtualbox/VirtualBox.so",) failed: libQt5Core.so.5: cannot open shared object file: No such file or directory
我安裝了qt5核心。事實上，因為我不斷收到 Qt5 錯誤，所以我最終做了
sudo apt install qt*
這並沒有解決我的問題。我甚至嘗試從原始程式碼建立 VirtualBox，如下這些說明。當我第一次開始嘗試從原始程式碼建置時，我也在該./configure步驟中遇到了 Qt5 錯誤。我最終從他們的網站安裝了 Qt5 並將構建指向它，如下所示：
./configure --disable-hardening --with-qt-dr=/opt/path/to/Qt
這實際上確實修復了 Qt 錯誤，但現在該kmk步驟最終失敗，然後如果我繼續按照說明進行操作，我實際上永遠不會獲得有效的建置。
我現在也嘗試過直接重新安裝 Ubuntu 3 或 4 次，但這並沒有幫助。這是其他問題之一在 Ask Ubuntu 上，該解決方案在哪裡並沒有真正幫助我，因為據我所知，我的系統輸出與唯一答案的工作系統相同。另一個問題沒有答案，唯一評論的建議是sudo apt install -f我顯然已經嘗試過的建議，並且沒有修復我的安裝。

我嘗試sudo apt install --reinstall libqt5core5a並不斷收到相同的錯誤。

我也嘗試直接從 oracle 網站安裝 VirtualBox。安裝的行為就好像它正在工作一樣，但隨後拋出相同的錯誤。

答案1
我想到了。基本上，我必須sudo apt install --reinstall package對很多不同的包進行操作，直到它最終起作用。我真的不知道為什麼，但光是安裝必要的軟體包是不夠的。我必須安裝然後重新安裝。就我個人而言，我做了：
sudo apt install --reinstall libqt5*sudo apt install --reinstall libdouble-conversion*- 然後我收到一條錯誤訊息，指出 xcb 插件無法正常工作，並且根據
ldd /usr/lib/x86_64-linux-gnu/libQt5XcbQpa.so我所做的輸出： sudo apt install libxcb-xinerama0*sudo apt install --reinstall libxcb-xinerama0*
然後VirtualBox就開始工作了。對於讀過我關於 gparted 也不起作用的評論的人來說，類似的過程也可以啟動並運行。這似乎應該由套件管理器處理。
