I am trying to deploy a flask app which uses openCV on heroku from my github respository . I included the heroku-buildpack-apt buildpack with python buildpack and I even tried the method given in this answer. On which I am getting the following error. Someone please help me to get this running.

  • if you're still having this issue, perhaps add some debugging details. and consider asking on another stackexchange, perhaps one closer to linux (this complains about packaging) or specific to server administration (https://serverfault.com/). – Christoph Rackwitz Jul 02 '22 at 11:30
  • Thanks for the reply and I managed to fix it back then itself. Turns out the issue was with the line endings of the proc file, they were set to windows line endings and not linux ones, changing them to linux ones did the trick @ChristophRackwitz – Aniket Mahule Sep 21 '22 at 10:23
