Downgrade of pkg during a pkgbase upgrade

[Emrion]

I'm testing the upgrade from 15.0-RELEASE-p10 (latest ports repos) to 15.1-RELEASE using pkgbase.
That works, but pkg is downgraded during the upgrade.

The command is:
pkg -o ABI="FreeBSD:15:amd64" -o IGNORE_OSVERSION=yes
-o REPOS_DIR=/etc/pkg/,/usr/local/etc/pkg/repos/,/tmp/pkgb-update/
upgrade -fr FreeBSD-base

Content of /tmp/pkgb-update/upg.conf:
FreeBSD-base: {
url: "pkg+https://pkg.FreeBSD.org/${ABI}/base_release_1",
signature_type: "none"
}

I get:
...
Installed packages to be DOWNGRADED:
pkg: 2.7.5 -> 2.6.2_1 [FreeBSD-base]
...

So, this time pkg comes from the base repo?
It's normaly in the ports repo.

After, when I want to upgrade some pkg, it works, but I get:
pkg: warning: database version 39 is newer than libpkg(3) version 38, but still compatible

That said, it can be upgraded anew to 2.7.5 with the ports repo.
I can also avoid this by temporary locking pkg before the pkgbase upgrade.

Can you tell me if this a bug or if it's normal?

Also, if I remove the force flag in the pkg command line, this problem disappear, but...
I stumble on another trouble when I upgrade to 15-STABLE.. This is maybe the only one, actually.

Same command line.

Content of /tmp/pkgb-update/upg.conf:
FreeBSD-base: {
url: "pkg+https://pkg.FreeBSD.org/${ABI}/base_latest",
signature_type: "none"
}

This time, I get:
The following 319 package(s) will be affected (of 0 checked):

Installed packages to be DOWNGRADED:
FreeBSD-acct: 15.1 -> 15.snap20260529234551 [FreeBSD-base]
FreeBSD-acpi: 15.1 -> 15.snap20260529234551 [FreeBSD-base]
FreeBSD-apm: 15.1 -> 15.snap20260613011050 [FreeBSD-base]
...

pkg calls this a downgrade whereas it's an upgrade. If I don't use the force flag, it does nothing.

this os expect we have no way to know if 15-stable is older or newer than 15.1-release or 15.x-release at some point it is an upgrade at some other point it is a downgrade

Thanks. Ok, I will deal with that.

As far as I know, STABLE can be the same than the new RELEASE version at some point. But, RELEASE is never ahead from STABLE.
