質問
I wrote this task to install git-core on Ubuntu. I am getting some weird errors, although it seems like the install finishing properly. Any idea why?

Here's the output with all the warnings. This doesn't happen with capistrano-2.

In this case, it's not really an error, and will have no impact on the installation of your packages
apt-get complains because it is not working inside a regular Unix terminal.
However, you can try to fix these warning by adding this directive in your Capistrano deploy file:
set :pty, true
