Can I install the downloaded 32 bit packages to 64 bit OS?

(now using UBUNTU 12.04(32bit) and going to install UBUNTU 12.04(64bit) on another PC.)

  • I guess for that you will have to install sudo apt-get install ia32-libs-multiarch – atenz Aug 1 '12 at 14:27

Yes, you can. See this question for more detailed instructions, but basically:

  1. Enable partner repositories
  2. Update apt-get
  3. Install 32-bit libraries
  4. Install 32-bit packages of your choice

Sometimes, the package will take care of the dependencies itself (particularly if you're getting it from a PPA) and all you need is for the partner repositories to be enabled.

Note: Most programs these days are available in 64-bit versions. If the program you're looking to install has one available, you should favor it over the 32-bit version, unless there are any known issues that technologically prevent you from using it (ie - it crashes on startup). 64-bit software is better equipped to leverage your hardware than 32-bit is, making it more efficient overall (and potentially allows the developers to add in features that weren't possible in the 32-bit version).
