When I run update.php from the "maintenance" folder I get this response:

"mediawiki/validator: 2.3.1 installed, 2.2.* required.

mediawiki/semantic-media-wiki: 2.5.2 installed, ~2.5 required.

mediawiki/maps: 4.2.1 installed, ~4.1 required.

Error: your composer.lock file is not up to date. Run "composer update" to install never dependencies"

But when I run "composer update" from the wiki's root directory, I get this message: "Nothing to install or update" and I still cannot run update.php. What could be wrong?

MediaWiki	1.28.2
PHP	7.0.15-0ubuntu0.16.04.4 (apache2handler)
MySQL	5.7.18-0ubuntu0.16.04.1

Thanks!
