[FIXED] Can't find/install libXtst.so.6?

Issue

I'm running Ubuntu 12.10 and I'm trying to install Netbeans 7.1(or later) I have the .sh file, but it won't install, the error appears here:

[2013-06-27 19:11:28.918]:      at org.netbeans.installer.Installer.main(Installer.java:81)
[2013-06-27 19:11:28.918]:     An error occured while initializing the NetBeans IDE installer UI.

I don't have the libXtst.so.6 file in any directory, and I can't seem to find it anywhere to download. Has anyone else run into this problem, or know a work around?

Solution

EDIT: As mentioned by Stephen Niedzielski in his comment, the issue seems to come from the 32-bit being of the JRE, which is de facto, looking for the 32-bit version of libXtst6. To install the required version of the library:

$ sudo apt-get install libxtst6:i386

---

Type:

$ sudo apt-get update
$ sudo apt-get install libxtst6

If this isn’t OK, type:

$ sudo updatedb
$ locate libXtst

it should return something like:

/usr/lib/x86_64-linux-gnu/libXtst.so.6       # Mine is OK
/usr/lib/x86_64-linux-gnu/libXtst.so.6.1.0

If you do not have libXtst.so.6 but do have libXtst.so.6.X.X create a symbolic link:

$ cd /usr/lib/x86_64-linux-gnu/
$ ln -s libXtst.so.6 libXtst.so.6.X.X

Hope this helps.
