bin/console assets:install fails

[jakenoble]

php /var/www/webroot/swz/deployer/releases/20180723171355/bin/console assets:
  install /var/www/webroot/swz/deployer/releases/20180723171355/web --symlink
   --no-debug --env=prod

This fails with no meaningful error. And I cannot see how to run it on the server via SSH myself and the release dir is removed. And I cannot find a way to flag it not to be removed so I can execute the command myself on the remove server to view the rea error.

I just see "Exit Code: 255(Unknown error)"
