Follow

<https://guide.macports.org/chunked/installing.macports.uninstalling.html>

Once you have done that, just follow the usual instructions to install 
MacPorts from scratch.

Whenever you upgrade your OS it is *mandatory* that you follow the 
migration guide

<https://trac.macports.org/wiki/Migration>

Not following that, precisely (which yes means uninstalling all ports 
and reinstalling them once upgraded), is a very good way to end up with 
the troubles you are having here.

Another bit of advice - *never* updating your ports after you install 
them is also not at all recommended, as it is also a good way to end up 
with troubles as when you do the updates are a lot bigger and more 
problematic the longer the time period since the last update. I 
recommend periodically running

 > sudo port sync
 > sudo port upgrade outdated

and

 > sudo port selfupdate

to keep your ports in good health.
