软件更新程序要求我安装更新，但在终端上没有检测到升级

  • 772

我打开我的笔记本电脑，看到一个弹出窗口，通知我有更新以及我是否愿意安装它们。我选择不：

在此处输入图像描述

我打开终端并运行sudo apt-get upgrade，但它没有安装任何东西：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Calculating upgrade... Done
The following packages have been kept back:
  libmm-glib0 libqmi-proxy modemmanager
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.

所以我去了仪表板并选择了我安装更新的软件更新程序。

这有什么逻辑解释吗？我的意思是为什么命令行没有检测到任何要升级的东西？

command-line update-manager

    GUI （软件更新程序）可能使用 dist-upgrade 而不是升级。升级选项之间的差异。

    从手册 ( man apt-get) 它告诉我们“升级”

    under no circumstances are currently installed packages removed, or
packages not already installed retrieved and installed. New versions of 
currently installed packages that cannot be upgraded without changing the 
install status of another package will be left at their current version.

    并在 dist-upgrade 部分继续说

    in addition to performing the function of upgrade, also intelligently
handles changing dependencies with new versions of packages...

    （复制自man apt-get）
