如何在 Debian Stable 中配置 apt-get，无法获得锁定 /var/lib/dpkg/lock

Question

我正在使用稳定版 Debian (8.1 - jessie)，安装自 Live (debian-live-8.1.0-amd64-xfce-desktop.iso)...

现在，开始安装所有其他东西，没有什么是可能的 (!)...apt-get 和 Synaptic 不工作...

与 apt-get install apache2: "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?".
with Synaptic 接口：标记 apache2, ... 当我按下 [apply] 时，它说，在警报中，"Could not apply changes, Fix broken packages first".

注意事项

我在桌面界面中使用 root 登录，并执行（没有错误提示）所有建议的更新，

 apt-get update
 apt-get upgrade
 apt-get dist-upgrade
 apt-get install -f

没什么可怕的问题...是/etc/apt/sources.list，需要评论旧的并添加新的
