安装xmind出错：没有JRE

我的PC机是Ubuntu 12.04 64位系统，已安装JDK，但在安装xmind时仍报找不到Java的错误，提示安装JRE。

首先，查看下xmind的依赖：

$ dpkg –info xmind-linux-3.4.0.201311050558_amd64.deb
new debian package, version 2.0.

因为我已经安装了JDK，所以忽略依赖文件，如下：

$ sudo dpkg –ignore-depends=sun-java6-jre -i xmind-linux-3.4.0.201311050558_amd64.deb

安装后，可以正常使用的。
