我正在尝试在装有 Ubuntu 14.10 的笔记本电脑上安装 MariaDB。每次我都会收到错误。所以，问题是 MariaDB 需要 libmysqlclient18 版本 10.0.16，但安装了 5.xx。如果我安装 10.0.16，我会收到新的错误，提示另一个应用程序需要 libmysqlclient18 以前的版本。我尝试执行MariaDB 安装指南页面，但没用。或者我做错了什么。

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
libmariadbclient18 : Depends: libmysqlclient18 (= 10.0.16+maria-1~utopic) but 5.5.41-0ubuntu0.14.10.1 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

答案1
似乎您有来自另一个应用程序使用的 mysql-client 库的工件。我建议这样做
sudo aptitude search libmysql | grep '^i'
这将显示已安装的 libmysql 版本，您可以尝试使用 apt 逐个删除这些版本。您安装的某个应用程序可能依赖于所述版本，并在此过程中强制删除自身。
答案2
看来我找到了解决方案。我像典型的 Windows 用户一样修复了它 :-) 只需删除所有 mysql 和 mariadb 包并安装 mariadb。
答案3
首先，彻底摆脱两个冲突的客户端：
sudo apt-get –purge remove libmariadbclient1
sudo apt-get –purge remove libmysqlclient18
然后再次尝试安装 mariadb。现在应该可以正常工作了。
sudo apt-get update
sudo apt-get install mariadb-server-10.1
最后，
sudo apt-get upgrade
确保一切恢复正常。
