Error: /opt/local/bin/port: port selfupdate failed: Error synchronizing MacPorts sources: command execution failed
I have tried to redownload macports and it still does not seem to work. I have also tried it without sudo and it still does not work. Does anyone have a solution to this problem? thanks.

I had that problem too. Even, like you, I re-downloaded the distribution and reinstalled.
That is until I read the manpage and tried the '-d' flag so
sudo port -d selfupdate
I tried it and surprisingly didn't find a command failing but successful completion. I didn't see any ports updated, but perhaps the error we saw were occurred after the ports tree was updated.
If it doesn't work, try it anyway, it'll at least point you in the right direction.

I had the same problem after upgrading to Yosemite, but since I found this post, I did not reinstall macports - I ran "sudo port -d selfupdate", had errors with c compiler failing, so I updated Xcode, ran "sudo port clean expat" after restarting, then ran "sudo port -d selfupdate" and all was well - thx you!
