Description (last modified by kencu (Ken))

Hi! I successfully installed MacPorts 2.6.4 in my Mac Pro 2019 with macOS Big Sur 11.1. I got errors when I tried "sudo port install gcc6". The error messages are as follows:

Welcome!

Regarding your connection issue, try opening this URL in a browser and see what happens <https://ywg.ca.packages.macports.org/mirror/macports/packages/libgcc7/>

If that works fine, try downloading a file from that url with curl and see what what happens

curl -O https://ywg.ca.packages.macports.org/mirror/macports/packages/libgcc7/libgcc7-7.5.0_0.darwin_19.x86_64.tbz2

The full details on how to debug this are here wiki:MisbehavingServers.

FYI -- gcc7/libgcc7 is quite old, and may not work / be able to be made to work on BigSur.

The current gcc flavour for you would be gcc10 -- will that work for you?

sudo port -v install gcc10
