 Error: Follow https://guide.macports.org/#project.tickets if you believe
 there
 is a bug.

 I'd love to know how i can at least partly keep my system up-to date e.g.
 forcing to ignore/skip errors like this or find out which applications i
 might need to deinstall or install old versions from a dmg or the like.
