Trouble installing dependancies/packages.

[Karasawa7]

I need to Install the following dependencies:

• libtxc_dxtn
• lib32-libtxc_dxtn
  
  
  I assumed I could just do

  sudo apt-get install libtxc_dxtn

  However I get

  Reading package lists... Done
  Building dependency tree       
  Reading state information... Done
  E: Unable to locate package libtxc_dxtn

  
  Am I doing something wrong? Or?
  
  I need to install these, because a game I want to play renders textures black, and the two dependencies are said to remedy it. I use Ubuntu 12.04

I think the package you mentioned is not available in Ubuntu repo. I think its available from 3rd party ( xorg-edgers ) repository.
You can check the link http://www.ubuntuupdates.org/ppa/xor...s?dist=precise

and install the PPA as mentioned in the link. Then try installing it as you did earlier. I am not sure if it will resolve your problem

Installed the 3rd party thing no problem, but got the same thing as before.

I'm a little new to Ubuntu, which probably limits my capability to explain things. Thank you for the quick response though.

However, the package I need "libtxc_dxtn" is there, on the link you gave me
Huh..

[Karasawa7]

The package was an umbrella, containing multiple (two, specifically) packages.
Opted to install each package in it separately, installed just fine. Let me see if it fixed my game issue. (even though this thread was initially about installing the packages themselves, which I've done. I'll mark this as solved)

You can use apt-cache search <search terms> to find the exact package name you need. I ran

apt-cache search libtxc dxtn

which produced

libtxc-dxtn-s2tc-dev - Development files for the S2TC library
libtxc-dxtn-s2tc0 - Texture compression library for Mesa
libtxc-dxtn-s2tc-bin - S2TC texture compression and conversion tools

Just FYI.
