 Hello,
 I am trying to solve this problem since many weeks, without success. I did
 "port selfupdate ;  port upgrade outdated". The error message is:
 --->  Attempting to fetch libgcc8-8.3.0_5.darwin_19.x86_64.tbz2 from

 for details.
 Error: Problem while installing libgcc8
 Error: Follow https://guide.macports.org/#project.tickets to report a bug.

 My OS versions is macOS Catalina v10.15.1
  I installed gcc9 and , and uninstalled gcc8 and libgcc8, but the problem
 with gcc8 still appears when I execute "port upgrade outdated".  I also
 reinstalled xcode, and the command line tools, without success.
 Maybe I am doing something wrong.
 Any help ?

 Thanks
