Your MySQL/MariaDB server version is too low and migrations failed. I have submitted a new error screen to better explain this.
There was an update that adds a query that checks a new table that doesn’t exist yet on your db server…

Resolution:

  1. Install supported version of MySQL (5.7.7) or MariaDB (10.2.2)
  2. Delete the partially migrated port_groups table ONLY IF IT IS WHERE YOU ARE STUCK lnms tinker --execute="DB::statement('DROP TABLE port_groups');"
  3. Migrate database lnms migrate
  4. Validate system ./validate.php
