Debian安装MySQL提示：Depends: libssl1.1 (>= 1.1.1) but it is not installable

Debian11安装MySQL一切正常，在Debian12中安装MySQL时候提示“Depends: libssl1.1 (>= 1.1.1) but it is not installable”，导致无法继续安装。 原因是缺少openssl的libssl，到Debian官网找到libssl软件包安装说明 ``` https://packages.debian.org/bullseye/libssl1.1 ``` 查看服务器硬件，是amd64还是intel，按需下载对应 deb 包。下载完成后，上传至服务器，然后开始安装 deb，这里以 amd64 为例 ``` sudo apt-get install ./libssl1.1_1.1.1w-0+deb11u1_amd64.deb ``` 安装成功提示如下 ``` Reading package lists...
