Can't self update with tarball

[jnojr@…]

Outbound 873 is blocked on my network, and there's nothing I can do about it. So I tried to use the tarball:

flamingo:~ joliver.sa$ tail -2 /opt/local/etc/macports/sources.conf
#rsync://rsync.macports.org/release/tarballs/ports.tar [default]
https://distfiles.macports.org/ports.tar.gz [default]

But:

flamingo:~ joliver.sa$ sudo port -d selfupdate
DEBUG: MacPorts sources location: /opt/local/var/macports/sources/rsync.macports.org/release/tarballs

You've configured MacPorts to fetch the ports tree via https, but selfupdate always uses rsync to fetch the base code; it cannot be configured to use https or another method. (See #38265.) You can use "sudo port sync" to sync the ports tree (via https, now that you've changed your sources.conf), and manually update MacPorts base when a new version is released, e.g. by downloading and installing the package from our web site. You can subscribe to the macports-announce mailing list if you'd like to be informed when new versions are released.
