Try this: sudo apt-get purge libgnutls26:i386
I don't know how or why you have the 32-bit version installed, but it looks like having a different version of the 32 bit library installed than the 64 bit version is making things complicated. Most people don't need the 32 bit version, so delete it. Then try apt-get dist-upgrade again.
