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?
解决：
sudo rm -rf /var/lib/dpkg/lock
sudo rm -rf /var/cache/apt/archives/lock
sudo apt-get update
ubuntu15.10安装后换源之后更新源出现Could not open lock file/var/lib/dpkg/lock等提示
