I've been in the mood when going from kubuntu 11.10 x64 to Ubuntu 12.04 and tried these solution without success. I always end up with loads of different errors.
Thank to this topic, I've managed to get rid of the trouble by :
dpkg -i /var/cache/apt/archive/*.deb
dpkg -i --configure libgcc1 libc6
Then all the previous dpkg commands again.
And then everything back to normal to continue the upgrade.
