安装Galera但mariadb存在于系统上

Question

我试图在ubuntu14.04系统上安装galera。它已经有了mariadb，而且还在工作。我怎么安装它？

我的命令：

sudo apt-get install -y rsync galera-3 mariadb-galera-server

它会产生错误

rsync is already the newest version.
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 mariadb-galera-server : Depends: mariadb-galera-server-5.5 (= 5.5.46+maria-1~trusty) but it is not going to be installed

试着用天赋来代替apt。它更聪明。它不仅会为您处理降级冲突的包，而且会提出一系列建议，询问您可能建议的工作方案中的哪一个。例如：

sudo aptitude install rsync galera-3 mariadb-galera-server

如果你还没有能力在你的机器上，得到它与

sudo apt-get install aptitude
