软件更新程序显示更新但不显示 apt-get

Question

弹出这个：

然而，当我在终端中运行 apt-get 时，我得到：

    sudo apt-get dist-upgrade 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Calculating upgrade... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

    sudo apt-get upgrade 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Calculating upgrade... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

这是怎么回事？为什么软件更新程序显示无法通过命令行安装更新？

Answer 1

如果 apt-get dist-upgrade 不起作用，请尝试以下操作之一，直到问题自行解决：

apt-get upgrade -f # 即使出现错误也继续升级

或者

apt-get dist-upgrade -f # 即使出现错误也继续 dist-upgrade
