ubuntu系统下怎么使用不了traceroute这一条命令 提示如下（怎么解决）：
upai@ubuntu:~$ traceroute www.upyun.com
The program 'traceroute' is currently not installed. You can install it by typing:
sudo apt-get install traceroute
upai@ubuntu:~$ sudo apt-get install traceroute
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?
upai@ubuntu:~$
