If you are getting following error during the install:
SQLSTATE42000: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes The SQL being executed was: ALTER TABLE `queue` ADD INDEX `channel` (`channel`)
Open the file /apps/console/migrations/m180206_121141_create_queue_table.php and look for:
'channel' => $this->string()->notNull(),
and make it
'channel' => $this->string(150)->notNull(),
Then save the file, remove the /apps/common/config/main-local.php file, drop existing created database tables which the installer managed to create so far, and reload your page in the installer, this time the error should go away.
