我正在尝试从 Ubuntu 21.10 升级到 Ubuntu 22.04。升级到 22.04 的通知也自动出现。但是升级没有成功。
尝试使用终端升级到 LTS 版本时，会打印以下消息
$sudo do-release-upgrade
Checking for a new Ubuntu release
Please install all available updates for your release before upgrading.
打印sudo apt upgrade以下消息：
The following packages have been kept back:

当尝试手动更新或安装上述任何一个包时，它只会打印一长串依赖错误。
我不知道如何解决这个问题。这个问题在这里已经被问过很多次了，AskUbuntu但是建议的解决方案对我来说都不起作用。
有什么方法可以抑制这些软件包中的错误并继续升级到 Ubuntu 22.04？

请备份您的个人数据并确保您拥有 jammy 的安装媒体以防万一。
在 /etc/apt/sources.list 中添加 jammy 更新源。
sudo nano /etc/apt/sources.list
并添加行
deb http://archive.ubuntu.com/ubuntu jammy-updates main restricted multiverse universe
然后刷新
sudo apt update && apt -s -f install
第二部分只是模拟。如果 apt 和 dpkg 都没有报错。
sudo apt -f install && sudo apt full-upgrade
