Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

The following information may help to resolve the situation:
The following packages have unmet dependencies:
mysql-server : Depends: mysql-community-server (= 8.0.24-1ubuntu16.04) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
我正在看互联网修复此问题的方法，但我找不到解决方案。
我在用着Linux Mint
更新：
运行命令 lsb_release -cs 来打印您的版本。
但是，您应该使用 apt 来安装而不是 dpkg，例如 sudo apt install ./mysql-apt-config_0.8.17-1_all.deb
使用：sudo apt install ./mysql-apt-config_0.8.17-1_all.deb

Note, selecting 'mysql-apt-config' instead of './mysql-apt-config_0.8.17-1_all.deb'
mysql-apt-config is already the newest version (0.8.17-1).

mysql 存储库配置错误，因为使用的代号是xenial而不是focal。使用以下命令修复 mysql 存储库（Ulyssa 基于 Focal）：
sudo sed -i 's/xenial/focal/g' /etc/apt/sources.list.d/mysql.list
然后运行：
sudo apt update
sudo apt install mysql-server
