Heroku installation on Ubuntu

Hi,

I’ve installed the Heroku on my workspace, however when I type any command, for example- heroku login or heroku version , it just shows the command- “heroku-cli: Installing core plugins…” and keep doing the same until I stop the installation manually.

Can somebody help me with what the actual issue is and how I can deploy the app on heroku!

What does that mean? What is "the Heroku"? What is your "workspace"?

for example- heroku login or heroku version , it just shows the command-
"heroku-cli: Installing core plugins..." and keep doing the same until I
stop the installation manually.

So you're not letting the command-line tools finish installing? Why?

Maybe if you provide exact steps to reproduce - it works as expected
from an Ubuntu 14.04 (via vagrant) instance here.
