Do you need 32-bit support for your installation?  If not, then use
dpkg to remove the 32-bit architecture.  Here are some useful
commands, if you don't need 32-bit support.

    dpkg --print-foreign-architectures
    dpkg -l | grep :i386
    sudo apt remove $(dpkg --get-selections | grep :i386 | awk '{print $1}'`)
    sudo dpkg --remove-architecture i386

Then run `apt update` and `apt upgrade` again.
