Installing lnav - indicates GnuPG keys are expired. How to get more current ones?

After a short discussion on IRC yesterday on how to install lnav, this should have worked, but doesn’t:

OCICLI http://software.opensuse.org/ymp/server:monitoring/openSUSE_Tumbleweed/lnav.ymp

The problem is that after an initial warning:

    # OCICLI http://software.opensuse.org/ymp/server:monitoring/openSUSE_Tumbleweed/lnav.ymp    If you continue, the following repositories will be subscribed:
        * http://download.opensuse.org/repositories/openSUSE:/Tumbleweed/standard/
        * http://download.opensuse.org/repositories/server:/monitoring/openSUSE_Tumbleweed/
    If you continue, the following software packages will be installed:
        * lnav
    Warning: unable to close filehandle properly: Bad file descriptor, <STDIN> line
        7 during global destruction (#1)
        (S io) There were errors during the implicit close() done on a filehandle
        when its reference count reached zero while it was still open, e.g.:
        
            {
                open my $fh, '>', $file  or die "open: '$file': $!
";
                print $fh $data or die "print: $!";
            } # implicit close here
        
        Because various errors may only be detected by close() (e.g. buffering could
        allow the print in this example to return true even when the disk is full),
        it is dangerous to ignore its result. So when it happens implicitly, perl will
        signal errors by warning.
        
        Prior to version 5.22.0, perl ignored such errors, so the common idiom shown
        above was liable to cause silent data loss.
        
    Continue? y/N

it will then show about two expired GnuPG keys:

How do I find the expiration dates of these and obtain/install new ones?
