我完全忘记了 MySQL 已经安装在这台特定的计算机上并且我安装了 MariaDB,我也不知道在同一台计算机上同时安装两个软件包的后果,我一直在尝试完全卸载这两个安装并删除两者的依赖关系其中。我已经在网上查找了几个关于如何执行此操作的教程,但我仍然无法运行 MySQL,您将在下面找到终端窗口的屏幕截图以及我尝试过的许多尝试解决方案的列表,不幸的是我有尝试了很多,以至于我无法回忆起我尝试它们的顺序,我只想安装一个有效的 MySQL,但不知何故,我无法从以前的安装中删除一些东西,并且 MySQL 安装不起作用,我获取 dpkg:警告。任何和所有的帮助将不胜感激。(Ubuntu 20.04)
这是终端窗口的屏幕截图。

更新
我已经删除了突触中的 Libmysqlclient21,因为它看起来已损坏,尝试从突触成功卸载 MySQL 并从突触重新安装它失败,显然有一个我找不到的正在运行的 MySQL 进程,这阻止了 mysql-server-8.0 的安装(mysql-client、client-8.0、client-core-8.0、server 和 server-core-8.0 重新安装就好了)。接下来你会发现屏幕截图 https://pastebin.ubuntu.com/p/pJCxYm5K2w/
还 - -
internal Error, No file name for mysql-server:amd64
好的,看起来 MySQL APT 存储库提供了
mysql-common
因此卸载所有本机 8.0 版本,但他们建议您不要在此处清除,只需卸载:然后,您应该能够进行安装:
最后,您可以通过运行以下命令来更新您的共享库:
这将替换现有版本。
可以在此处找到可用软件包的列表和更多信息。
不明白怎么回事,我是通过具有完全管理权限的用户帐号远程访问ubuntu机器的,但是不是安装ubuntu时创建的帐号,现在我终于直接访问电脑并登录了原始帐户,令我惊讶的是,当我尝试通过突触卸载所有 MySQL 槽时,我根本没有收到警告或错误,只是为了安全起见我运行以下命令
根本没有错误或警告,所以我启动了突触并重新安装了 mysql-server(突触处理了依赖项),安装正确完成。这对我来说毫无意义,因为具有完全管理权限的用户帐户应该具有完全访问权限,但是有它,MySQL 已安装并正在运行
