Could not open lock file/var/lib/dpkg/lock的解決
在ubuntu系統中利用apt-get install something的時候，有時候會出現無法獲得鎖的權限問題。這是因為有另外一個進程在占用鎖。類似以下的錯誤提示：
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
解決辦法：
sudo rm -rf /var/lib/dpkg/lock
sudo rm -rf /var/cache/apt/archives/lock
sudo apt-get update
sudo dpkg --configure -a
運行以上四條命令
