Because of this message:

Warning: The lock file is not up to date with the latest changes in composer.json.
You may be getting outdated dependencies. It is recommended that you run `composer update` or `composer update <package name>`.

In order to have robrichards/xmlseclibs (3.1.1), I update only the robrichards/xmlseclibs in the composer files.

php composer.phar update robrichards/xmlseclibs --ignore-platform-reqs

The "muglug/package-versions-56" plugin was skipped because it requires a Plugin API version ("^1.0") that does not match your Composer installation ("2.0.0"). You may need to run composer update with the "--no-plugins" option.
Do not run Composer as root/super user! See https://getcomposer.org/root for details
Continue as root/super user [yes]? yes
