ubuntu 安装net-tools

ubuntu下使用apt-get,得到下面error：

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：

1.delete the lock file

sudo rm /var/lib/apt/lists/lock
2.delete the lock file in the cache directory

sudo rm /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock

Thanks！
