Hi I'm on step 4 where you install the Heroku CLI.
Its saying failed to fetch http://cli-assets.heroku.com/branches/stable/apt ./heroku_5.6.29-1amd64.deb
it says 403 Forbidden [IP 220.127.116.11 80]
It also says unable to fetch some archives, maybe run apt-get update or try with --fix missing?
I'm not sure what to do here, any help would be appreciated thank you.
