看起来您错过了更新频道。
当我运行时，apt show libssl-dev -a我得到了列出的两个版本的包：
Package: libssl-dev
Version: 3.0.2-0ubuntu1.6
Depends: libssl3 (= 3.0.2-0ubuntu1.6)
APT-Sources: http://archive.ubuntu.com/ubuntu jammy-updates/main amd64 Packages
Package: libssl-dev
Version: 3.0.2-0ubuntu1
Depends: libssl3 (= 3.0.2-0ubuntu1)
APT-Sources: http://archive.ubuntu.com/ubuntu jammy/main amd64 Packages
（为简洁起见，输出减少到最低限度）
如您所见，您使用的软件包版本来自常规渠道，而所需的版本来自jammy-updates。
将频道添加到您的sources.list：
deb http://archive.ubuntu.com/ubuntu/ jammy-updates main universe restricted
当您这样做的时候，您可能还想添加jammy-security。
deb http://security.ubuntu.com/ubuntu/ jammy-security main universe restricted
