我在 Ubuntu 22.04 LTS 上安装了 git，但最近它不知何故被卸载了。git --version显示Command 'git' not found, but can be installed with: sudo apt install git.
尝试再次安装，我收到此错误：
The following packages have unmet dependencies:
git : Depends: git-man (< 1:2.39.1-.) but 1:2.39.2-0ppa1~ubuntu22.04.1 is to be installed
E: Unable to correct problems, you have held broken packages.
我已经跑了sudo apt update sudo apt upgrade，并确保没有任何阻碍。sudo apt install -f也没有工作。
编辑：apt policy显示：

编辑 2：通过软件和更新删除现有的 PPA 是有效的。https://askubuntu.com/questions/140246/how-do-i-resolve-unmet-dependency-after-adding-a-ppa

我也有同样的问题。我在某个时候添加了 ppa:git-core/ppa 并忘记了它。您的 apt 政策中也有它。
apt policy |grep git

我发现的最简单的解决方案是删除 PPA直到维护者解决该问题。
sudo apt install ppa-purge
sudo ppa-purge ppa:git-core/ppa
sudo apt update
sudo apt install git
然而，它确实给我留下了一个稍旧版本的 git。如果有人找到解决依赖性的方法，请分享。希望包维护者尽快做到这一点:)
