我有一个BQ Aquaris E5 Ubuntu 版电话。
通过手机更新和升级是否apt-get涵盖 Ubuntu 通过用户界面提供的所有更新（因为我知道他们进行二进制差异更新，即完全不同的东西）？我正在使用以下命令：
sudo su
mount -o remount,rw /
apt-get update
apt-get safe-upgrade
换句话说：我可以用该apt-get方法替换 GUI 更新吗？
我想使用，因为我正在安装原生的 Ubuntu 程序，apt-get例如emacs和。我购买 Ubuntu 手机的实际原因是我可以将 emacs 与 org-mode 一起使用。org-modelatex
（也可以看看这问题。）
我的第一次尝试看起来非常有希望。该文件/etc/apt/sources.list包含以下内容。它看起来apt-get应该能完成它的工作。
