Ubuntu 64位上jd-gui工具打开出现问题的解决方法

    最近在研究APK的反编译，前期搭建环境，下载dex2jar工具和jd-gui工具，dex2jar可以把apk包里的classes.dex文件反编译成jar文件了，但是我的jd-gui运行时却报错了，提示：

    error while loading shared libraries：

    libgtk-x11-2.0.so.0:cannot open shared object file: No such file or directory.

这个其实是amd64位兼容32位库的问题，网上有答案说 sudo apt-get install ia32-libs-gtk，但是我做了以后还是报错：

............

The following packages have unmet dependencies：

   ia32-libs：Denpens：ia32-libs-multiarch

后来我在外国一个网站上找到了解决方法，如下：

First a downgrade is required and done with the following: create the 'preferences' file:

sudo vi /etc/apt/preferences

and insert the following lines:

Package: *
Pin: release a=precise*
Pin-Priority: 2012

enter

:wq

 to
write the file. Pin-Priority must be greater than 1000.

Then you may downgrade the offending applications with:

sudo apt-get dist-upgrade

Then you may install packages that complained about dependencies, like 

sudo
apt-get install ia32-libs-multiarch

, or 

sudo
apt-get install ia32-libs

.

Finally, you should remove the file you just created:

sudo rm /etc/apt/preferences

because else no new updates would be found.

Hope this helps you too!

搞定，外国的人真牛逼，再次赞一下。
