poudriere no longer pre-fetching pkgs

Hi,

OS : FreeBSD 14.3-STABLE stable/14-n271679 amd64 1403502 1403502
poudriere version : poudriere-git-3.4-pre
pkg --version 2.2.1

The problem appears to be that, although poudriere says it fetches
the pkg list from pkg.freebsd servers, says it's up-to-date,
it then says it failed to fetch the repository, so nothing gets
pre-fetched.

The relevant part of poudriere.conf :

#####################################
# Set to always attempt to fetch packages or dependencies before building.
# XXX: This is subject to change
# Default: off; requires -b <branch> for bulk or testport.
PACKAGE_FETCH_BRANCH=latest

# The branch will be appended to the URL:
PACKAGE_FETCH_URL=pkg+http://pkg.FreeBSD.org/\${ABI}
#####################################
