Cannot Add PPA Behind Proxy Ubuntu 14.04

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.

Here is Solutions:

We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.

Solution 1

You need to export your proxy environment variables using

export http_proxy=http://username:[email protected]:port/
export https_proxy=https://username:[email protected]: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.

Note: Use and implement solution 1 because this method fully tested our system.
Thank you 🙂
