我正在尝试安装奶酪
ubuntu@ubuntu:/usr/src/linux-headers-3.5.0-23-generic$ sudo apt-get install cheese
[sudo] password for ubuntu:
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?
如何解决这个问题，请帮忙。
