Question

我试图在Ubuntu 20.04中安装/删除并重新安装/修复Mysql和Workbench，但始终收到此消息：

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安装时，出现此结果：

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。但是我找不到它。

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关系，请在上述命令的末尾附加软件包。

之所以显示此信息，是因为当有多个相互依赖的程序包时，仅删除其中一个将破坏依赖关系计数。

因此，同时删除它们可确保不会损坏软件包。

如果发现其他问题，请还原
