当我更新和升级时，我显示这些行以下包已被保留：mysql-utilities 0 升级，0 新安装，0 删除和 1 未升级。

但是当我使用 dist-grade 时，我会显示以下几行

sudo apt-get dist-upgrade
[sudo] password for anki:

0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.


sudo apt-get upgrade

无法升级

答案1

在更新或安装某些东西之前，第一步总是运行sudo apt-get update

第二步是运行你的sudo apt-get upgrade或sudo apt-get dist-upgrade

最后一点，如果没有什么可升级，那么它就不会升级任何东西。
