- drupal/console 1.9.10 requires drupal/console-core ^1.9.8 -> satisfiable by drupal/console-core[1.9.8].
- Root composer.json requires drupal/console ^1.9.10 -> satisfiable by drupal/console[1.9.10].
Something of a follow-up to https://github.com/hechoendrupal/drupal-console/issues/4343 - I was halfway through making a ticket on that repo - as drupal/console isn't updating - but I think I've now realized why not.
