How to Resolve Missing libXtst.so.6 Error When Installing NetBeans on Ubuntu?

How do I fix the libXtst.so.6 missing error when trying to install NetBeans on Ubuntu 12.10?

# Check if the library is missing
ls /usr/lib/libXtst.so.6

The error message "libXtst.so.6: cannot open shared object file: No such file or directory" indicates that the required library is not installed on your system. This library is essential for GUI applications that use the X Window System, and its absence can prevent the installation of applications like NetBeans.

# Command to install the library on Ubuntu
sudo apt-get update
sudo apt-get install libxtst6

# For 32-bit compatibility on a 64-bit system
sudo apt-get install libxtst6:i386

Causes

• The library libXtst is not installed on your system.
• The system is missing the required 32-bit version of the library if using a 64-bit OS.
• Improper system configuration or missing dependencies.

Solutions

• Install the missing library using the command: sudo apt-get install libxtst6
• If you are on a 64-bit system, ensure you have the 32-bit compatibility libraries: sudo apt-get install libxtst6:i386
• Reboot your system after installation to ensure all changes take effect.
• Check for additional dependencies needed for NetBeans in the installation FAQ or documentation.

Mistake: Trying to run the installation without the necessary libraries installed.

Solution: Always check for and install all dependencies before running software installers.

Mistake: Not updating the package list before installing.

Solution: Run sudo apt-get update to ensure you have the latest package information.
