Debian 9.9 x64 安裝 Virtualbox guest addition 與安裝 Qt 5.5.0 x64

Debian 9.9 裝好後安裝 virtualbox guest addition 會出現找不到 kernel header 錯誤。執行以下步驟可以解決：

1. apt-get update && apt-get upgrade
2. apt-get install build-essential module-assistant
3. m-a prepare

再插入 guest addition。此時如果 UI 選執行，仍會有錯誤。要改到 /media/cdrom 之下執行：sh VBoxXXXXXX.run 檔案。

執行 Qt 5.5.0 run 檔，出現：

解決：apt-get install libssl1.0-dev

再執行出現 No marker found, stopped after 1.00 MiB. 錯誤。這是因為 run 檔不完整，下載完整再執行就可以了。
