the reason you can not update 20 is that 20 is NOT supported anymore
fedora 20 went END OF LIFE on June 23 2015
there ARE no updates and there will NEVER BE ANY
upgrade to the current Fedora 22
it is not likely that "fed-up" will work skipping a version
back up your date
reformat and do a new install with 22
