mysql - 尝试在 Ubuntu 20.04 中安装 mysql 时未满足的依赖项

Question

我尝试在 Ubuntu 20.04 中安装/删除并重新安装/修复 Mysql 和 Workbench，但总是收到以下消息:

Building dependency tree       
Reading state information... Done
mysql-server is already the newest version (8.0.20-2ubuntu20.04).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libmysqlclient21 : Depends: mysql-common (>= 8.0.20-2ubuntu20.04) but 5.8+1.0.5ubuntu2 is to be installed
 mysql-client : Depends: mysql-community-client (= 8.0.20-2ubuntu20.04) but it is not installable
 mysql-community-test : Depends: mysql-community-server (= 8.0.20-2ubuntu20.04) but it is not installable
                        Depends: mysql-community-client (= 8.0.20-2ubuntu20.04) but it is not installable
                        Depends: libjson-perl but it is not going to be installed
                        Depends: mysql-community-server-core but it is not installable
 mysql-server : Depends: mysql-community-server (= 8.0.20-2ubuntu20.04) but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

当我尝试 sudo apt --fix-broken install 时，会出现:

The following packages have unmet dependencies:
 libmysqlclient21 : Depends: mysql-common (>= 8.0.20-2ubuntu20.04) but 5.8+1.0.5ubuntu2 is installed
 mysql-client : Depends: mysql-community-client (= 8.0.20-2ubuntu20.04) but it is not installable
 mysql-community-test : Depends: mysql-community-server (= 8.0.20-2ubuntu20.04) but it is not installable
                        Depends: mysql-community-client (= 8.0.20-2ubuntu20.04) but it is not installable
                        Depends: libjson-perl but it is not installed
                        Depends: mysql-community-server-core but it is not installable
 mysql-server : Depends: mysql-community-server (= 8.0.20-2ubuntu20.04) but it is not installable
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
E: Unable to correct dependencies

对不起，我确定有一个简单的解决方案..但我找不到。

尝试申请sudo apt autoremove libmysqlclient21 mysql-client mysql-community-test mysql-server如果出现任何其他新的未满足的依赖项，请在上述命令的末尾附加该包。
这是因为当有几个包相互依赖时，只删除一个会破坏依赖计数。
因此，同时移除它们可确保不会损坏包装。
如果您发现任何其他问题，请还原
