I'm migrating to a new desktop as my server/workstation. Postfix-3.3.2 was installed so I just upgraded to -3.4.6. When I ran postfix set-permissions upgrade-configuration it returned chown: cannot access '/usr/doc/postfix-3.3.1/README_FILES': No such file or directory
I cannot find the set-permissions script so I can fix the version error. What is the proper way to resolve this issue? TIA, Rich
