自从我从升级Ubuntu 14.04 LTS到Ubuntu 16.04 LTS 更新程序一直是一个大问题。
默认情况下，其设置为：自动检查更新|日常的，到目前为止还不错。但是当我去：Ubuntu 软件中心 |更新 它说有新的更新。例如：网页浏览器|图像魔术|Ubuntu 安全顺便提一下3。
然后当我点击安装按钮有时会以橙色显示安装进度，很好。但当安装完成时安装按钮再次弹出，就像根本没有安装一样，并且相同的更新出现在列表中，就像什么都没有做一样。
但如果我继续安装其他一些更新，并且3在......之外5更新后会出现一个空白页，显示已更新。
我现在有三个问题：
为什么这些不像其他的一样自动更新？
为什么安装完成后更新不会从列表中消失？
我没有安装的另外两个更新去哪儿了？
因此，这是运行后的结果： sudo apt 更新 && sudo apt 升级 终端中的命令。
PC 和终端已经开了一整晚了，它仍然显示58%
