I had several viewers and other 32 bit apps installed on Ubuntu 10.04 LTS 64 and they all ran fine. Until I ran the upgrade to 12.04 64. Now none of my previously installed 32 bit apps run and 32 bit apps can't be installed.
Running the command "sudo apt-get install ia32-libs-multiarch" yields a rsult of "The following packages have unmet dependencies: ia32-libs-multiarch:i386 : Depends: libcurl3:i386 but it is not going to be installed E: Unable to correct problems, you have held broken packages."
Attempting to add libcurl3:i386 via apt-get yields more unmet dependencies, and they yield yet more unmet dependencies, and on and on.
Is there a depository I'm missing that none of the How-To's have mentioned?
I agree with the previous post that the 64 bit versions of Ubuntu should have 32 bit compatibility by default, like other distros do (and OS X and Win7).
