Upgrade from 14.3 to 15

During the upgrade, I adjusted the FreeBSD.conf file to the recommended
setting put forward by the upgrade process.

Now when I trying to update pkg or to re-install apps, I get multiple error
lines like this:
pkg: packagesite URL error for pkg+
http://pkg.FreeBSD.org/FreeBSD:14:amd64/latest/data.pkg -- pkg+:// implies
SRV mirror type
Unable to update repository FreeBSD-kmods
Error updating repositories!

Tried to find the updated .conf file in /usr/local/etc/pkg/repos, am told
that directory doesn't exist.

I put the following FreeBSD.conf file in the /usr/local/etc/ directory, but
to no avail.  At a bit of a loss.

# To disable a repository, instead of modifying or removing this file,
# create a /usr/local/etc/pkg/repos/FreeBSD.conf file, e.g.:
#
#   mkdir -p /usr/local/etc/pkg/repos
#   echo "FreeBSD-ports: { enabled: no }" >
/usr/local/etc/pkg/repos/FreeBSD.conf
#   echo "FreeBSD-ports-kmods: { enabled: no }" >>
/usr/local/etc/pkg/repos/FreeBSD.conf
#
# Note that the FreeBSD-base repository is disabled by default.
#
#  url: "pkg+http://pkg.FreeBSD.org/${ABI}/latest",
FreeBSD-ports: {
  url: "pkg+https://pkg.FreeBSD.org/${ABI}/quarterly",
  mirror_type: "srv",
  signature_type: "fingerprints",
  fingerprints: "/usr/share/keys/pkg",
  enabled: yes
}
FreeBSD-ports-kmods: {
  url: "pkg+https://pkg.FreeBSD.org/${ABI}/kmods_quarterly_${VERSION_MINOR}
",
  mirror_type: "srv",
  signature_type: "fingerprints",
  fingerprints: "/usr/share/keys/pkg",
  enabled: yes
}
FreeBSD-base: {
  url: "pkg+https://pkg.FreeBSD.org/${ABI}/base_release_${VERSION_MINOR}",
  mirror_type: "srv",
  signature_type: "fingerprints",
  fingerprints: "/usr/share/keys/pkgbase-${VERSION_MAJOR}",
  enabled: no

Grateful for anything I am missing here.  Thank you all.
