At some point in the past you decided to install an unreleased development version of MacPorts ("2.1.99"), and based on the problem you're experiencing, you installed it before that ticket was fixed. All development versions' version numbers end with ".99". Selfupdate won't update you to 2.1.2 because "2.1.99" appears to be greater than "2.1.2" even though in this case it's not. You should force the selfupdate to run, thus upgrading you to 2.1.2 and getting you back to standard released MacPorts versions. Thereafter selfupdate will work normally again.

sudo port -f selfupdate
