Requires code modifications Locate any standard plugin in moodle that has db/install.php (for example, auth/cas/db/install.php ) Add the following code to the _install() function: $roleid = create_role('Dummy role', 'mydummyrole', '', ''); assign_capability('moodle/user:editownprofile', CAP_ALLOW, $roleid, context_system::instance()->id);   foreach (get_role_archetypes() as $archetype) { if (!in_array($archetype, ['guest', 'user', 'frontpage'])) { $roleid = create_role($archetype . ' Copy', $archetype . 'copy', '', $archetype); assign_capability('moodle/user:editownprofile', CAP_ALLOW, $roleid, context_system::instance()->id); } } Initialise and run unittests on accesslib and enrol_self and make sure they pass: php admin/tool/phpunit/cli/util.php --drop php admin/tool/phpunit/cli/init.php ./vendor/bin/phpunit lib/tests/accesslib_test.php ./vendor/bin/phpunit enrol/self/tests/self_test.php
