I have been using Ubuntu 64-bit for about 2 years now, & during that I had came across many 32-bit packages that I wanted to run them where no 64-bit version is provided of the same application. Though when ever I tried to install a 32-bit package on my 64-bit Ubuntu, I was always treated with the following error message:
‘package architecture (i386) does not match system (amd64)’
Many times I was able to avoid the above error by using the following command to install the desired package:
sudo dpkg -i –force-architecture pkgname_i386.deb
–force-architecture <== will tell Ubuntu to allow the installation of 32-bit package on the 64-bit version of Ubuntu.
