I have seen this too. With a little digging I located the code that deals with this functionality.

Two issues spring to mind when I read the comments below.

  • the order of your repositories matter and
  • if the repository description doesn't match the installed description then it will show an upgrade version 
     # 3. Send the installed version to the Repository for checking.
 # I used to only upgrade from the place it came from. Now it will com
+e
 # from the current repository.
    my $res = $pkg->uptodate($target);
    unless ($res->ok) {
    return Error("bundled package - no upgrade available")
      if $bundled;
    return $res;
    }
    my ($uptodate, $newversion) = $res->result_l;

    # 4. Return uptodate(t/f), newversion, oldversion, bundled(t/f):
    return List($uptodate, $bundled, $precious, $newversion, $ver_p);
}

# Find the first repository containing the package, and report whether
+ the
# package is up-to-date w.r.t that repository.
sub uptodate {
    my $o = shift;
    my $target = PPM::UI::get_targ(shift)->result;
    my $desc = $o->describe($target);
    if ($o->{current_rep} and $desc and $desc->ok) {
    my $u2d = $o->{current_rep}->uptodate(
        $target,
        $o->{id},
        $desc->result->version_osd,
    );
    return $u2d;
    }
    Error("package $o->{rawname} not found in repositories");
}

    If I set the first repository to be the "ActiveState Package Repository" (which is where the upgrade is).Then request the upgrade information and issue a describe on what was found I get the following.

    The author is missing in the repository for some reason. Interestingly if I look at the raw out from describe it is listed.

    I may be incorrect but I don't believe I have seen this issue with packages from Uwinnipeg. Maybe it is an ActiveState repository issue?
