[问题]更新源后执行sudo apt-get dist-upgrade有错误

[午夜游荡]

jimmieking@jimmieking-laptop:~$ sudo apt-get dist-upgrade
E: 无法获得锁 /var/lib/dpkg/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
请问这是怎么回事？

[雕啸长空]

你是同时开着如新立得之类的软件,或是正在用dpkg安装软件？
系统已经给出了提示了
