Sometimes we find we want to install a program for which only packages available for an architecture. If your distribution is installed with amd64 architecture but the package is only for i386 can force the installation to ignore the differences. Often a program compiled for i386 on amd64 work properly. The command to do is:

sudo dpkg -i --force-architecture paquete_i386.deb

Where paquete_i386.deb package will be the program file you want to install. Thus ignore the divergence with the system architecture and try to install the package normally.

If the installed package malfunction can uninstall it with:

sudo dpkg -r nombre_paquete

Where package_name is the name of the package installed, not the name of the file that we call in the previous step.
