Cannot Add PPA Behind Proxy Ubuntu 14.04

Question

I am unable to add a repository via the command line on Ubuntu 14.04. Apt-get works perfectly fine, and I am able to update the system. I have configured my /etc/apt/apt.config file as follows:

Acquire::http::proxy "http://<username>:<password>@<proxy address>:<port>/";

For example, when trying to add the repository for y-ppa-manager, I receive:

add-apt-repository ppa:webupd8team/y-ppa-manager
Cannot add PPA: 'ppa:webupd8team/y-ppa-manager'.
Please check that the PPA name or format is correct.

If you need any more info., feel free to ask.

Solution

You need to export your proxy environment variables using

export http_proxy=http://username:password@host:port/
export https_proxy=https://username:password@host:port/

and then tell sudo to use them using:

 sudo -E add-apt-repository ppa:webupd8team/y-ppa-manager

or open your /etc/sudoers file (using sudo visudo) and append

Defaults env_keep="https_proxy"

to the end of the file.

I have a blog on this, have a look at it for more details.

Thank you so much Jobin for the prompt reply! I used Method 1 from your blog, so I don't have to remember the "-E" each time.

In my case the problem was solved by this method: askubuntu.com/questions/355729/cant-add-any-ppas I mention this because it was not so easy to find in google (in my case the results point to this kind of solutions).
