Bug 272420: ports-mgmt/pkg: pkg-1.20.1_1 ssh:// repos no longer working
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=272420



--- Description ---
After updating pkg, ssh:// repositories stopped working.

Typical output (username, host and path removed for privacy reasons)


doas pkg upgrade

Updating custom repository catalogue...
pkg: Invalid url: 'ssh://user@host/path/to/packages/meta.conf'
pkg: Invalid url: 'ssh://user@host/path/to/packages/meta.txz'
repository custom has no meta file, using default settings
pkg: Invalid url: 'ssh://user@host/path/to/packages/packagesite.pkg'
pkg: Invalid url: 'ssh://user@host/path/to/packages/packagesite.txz'
Unable to update repository custom
Error updating repositories!


Error messages are incorrect because I was able to update seconds before.

Has ssh:// been silently depreciated? I ask this because I recall some similar
behaviour when another url scheme was depreciated without any end user
notifications.
