在ubuntu16.04下安裝git，出現以下問題：

E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) 
E: Unable to lock the administration directory (/var/lib/dpkg/)

sudo rm /var/lib/apt/lists/lock
sudo rm /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock
sudo dpkg --configure -a

原因可能是已經打開了Synaptic 包管理器的GUI介面，同時想通過在終端輸入sudo apt-get install安裝軟體。
