I have deployed portfolio app recently. Now, I want to update my app through different machine(linux mint 14).So, to update my app, definitely I need to install heroku toolbelt on my machine, latter on I can go forward with remaining things. Right?.

So, After that
I have followed the Google search,stack overflow search to resolve the problem.I am trying to install it through some other process which is identified through stack overflow, but still it is not solved my problem and it is showing up error with libnss3 dependencies as
libnss3-1d : Depends: libnss3 (= 3.13.1.with.ckbi.1.88-1ubuntu7) but 3.14.3-0ubuntu0.12.10.1 is installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
E: Unable to correct dependencies
I have replaced this libnss3.13.1.with.ckbi.1.88-1ubuntu7 with libnss3.14.3-0ubuntu0.12.10.1 in order to support Google-chrome browser.
But it is not supported for Heroku. If i will install the previous versioned libnss3 then i should remove google-chrome.I need google chrome because it provides best developer tool support for debugging and profiling the app.
Please help me to resolve this installing heroku-toolbelt problem.
Thanks.

Answer 1

Try
wget -qO- https://toolbelt.heroku.com/install.sh | sh
And then add the Heroku CLI to your PATH using:
echo 'PATH="/usr/local/heroku/bin:$PATH"' >> ~/.profile

Answer 2

I think the error "/usr/bin/env: ruby: No such file or directory" means you need to install Ruby.
