Attempting to run the recommended .circleci/setup-heroku.sh at the end of my 2.0 script fails with permissions issues:

I run into the same issue following the Heroku Deployment Integration Guide.

Instead of this snippet in the .circleci/setup-heroku.sh script:

wget https://cli-assets.heroku.com/branches/stable/heroku-linux-amd64.tar.gz
mkdir -p /usr/local/lib /usr/local/bin
tar -xvzf heroku-linux-amd64.tar.gz -C /usr/local/lib
ln -s /usr/local/lib/heroku/bin/heroku /usr/local/bin/heroku

I removed it and replace it with:

 wget -qO- https://cli-assets.heroku.com/install-ubuntu.sh | sh

found in the Heroku CLI documentation

Update: You can also use sudo. The Project Walkthrough guide has been updated to reflect this:

...
sudo mkdir -p /usr/local/lib /usr/local/bin
sudo tar -xvzf heroku-linux-amd64.tar.gz -C /usr/local/lib
sudo ln -s /usr/local/lib/heroku/bin/heroku /usr/local/bin/heroku
