Hello ! I’m trying to deploy a rails 5 app with ubuntu 16.04 etc… On cap production deploy I get the following error on deploy:migrate

INFO [deploy:migrate] Run rake db:migrate DEBUG [15816e11] Running if test ! -d /home/deploy/app/releases/20170313091718; then echo “Directory does not exist ‘/home/deploy/app/releases/20170313091718’” 1>&2; false; fi as deploy@138.68.83.124 DEBUG [15816e11] Command: if test ! -d /home/deploy/app/releases/20170313091718; then echo “Directory does not exist ‘/home/deploy/app/releases/20170313091718’” 1>&2; false; fi DEBUG [15816e11] Finished in 0.306 seconds with exit status 0 (successful).
