Failed to add the host to the list of known hosts (/app/.ssh/known_hosts). heroku


It was due to private git repository. In gem file there was:git param, I had provided , was causing bundler to try to pull it over ssh.

gem “jquery-treeview-rails”, :git => ‘git@github.com:kclair/jquery-treeview-rails.git’

to

gem “jquery-treeview-rails”

fatal: ‘heroku’ does not appear to be a git repository


I was facing same issues, When i cloned a client project and he had already created heroku server. Even he collaborated me to his account.

Below googled solution worked for me.

git remote add heroku git@heroku.com:appname.git

Where appname is the name of your app.

After that

git push heroku master

(assuming you want to push the master branch)
