无法安装mysql-server与'sudo apt安装mysql-server‘

Question

我是linux的新手，我遇到了一个问题:在从mysql-apt-config_0.8.17-1_all.deb下载mysql官方页面并使用以下方法配置它之后，无法安装mysql：

我得到了sudo dpkg -i mysql-apt-config_0.8.17-1_all.deb：

(Reading database ... 360760 files and directories currently installed.)
Preparing to unpack .../mysql-apt-config_0.8.17-1_all.deb ...
Unpacking mysql-apt-config (0.8.17-1) over (0.8.17-1) ...
Setting up mysql-apt-config (0.8.17-1) ...
Warning: apt-key should not be used in scripts (called from postinst maintainerscript of the package mysql-apt-config)
OK

我得到了sudo dpkg-reconfigure mysql-apt-config：

Warning: apt-key should not be used in scripts (called from postinst maintainerscript of the package mysql-apt-config)
OK

当输入sudo apt install mysql-server时，我得到：

Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
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.

我在网上找办法解决这个问题，但我找不到解决办法。

我在使用Linux

更新：

运行命令lsb_release -cs打印您的版本。

但是，您应该使用apt来安装，而不是像这样使用dpkg来安装./mysql-_0.8.17-1_all.deb

使用：sudo apt install ./mysql-apt-config_0.8.17-1_all.deb

[sudo] password for dev:

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，因为使用的代码名是xenial而不是focal。使用以下命令修复mysql存储库(Ulyssa基于焦点)：

sudo sed -i 's/xenial/focal/g' /etc/apt/sources.list.d/mysql.list

然后跑：

sudo apt update
sudo apt install mysql-server
