我正在尝试在 ubuntu server 14.04 上安装 motion，但 apt-get 找不到该包？从我读到的内容来看，它应该能够找到它。请问有人能告诉我如何安装它吗？
答案1
我最终将 trusty-update 和 trusty-backports 添加到 /etc/apt/sources.list
，然后将 main、restricted、universe 和 multiverse 添加到所有这些中
deb http://security.ubuntu.com/ubuntu trusty-security main restricted multiverse universe
deb-src http://security.ubuntu.com/ubuntu trusty-security main restricted multiverse universe
deb http://security.ubuntu.com/ubuntu trusty main restricted multiverse universe
deb-src http://security.ubuntu.com/ubuntu trusty main restricted multiverse universe
deb http://security.ubuntu.com/ubuntu trusty-updates main restricted multiverse universe
deb-src http://security.ubuntu.com/ubuntu trusty-updates main restricted multiverse universe
deb http://security.ubuntu.com/ubuntu trusty-backports main restricted multiverse universe
deb-src http://security.ubuntu.com/ubuntu trusty-backports main restricted multiverse universe
