How do I enable the "partner" repository?

I keep seeing places refer to the "partner" repository as a place I can get software, how can I enable this repository? Please specify how to do this graphically and via command line.

Solution 1:

GUI Way:

Click on the ubuntu button, then search for "Software Sources" (or "Software & Updates" on Ubuntu 16.04+) and go to the "Other Software" tab.

enter image description here

Command Line Way:

Open the sources.list file: gksudo gedit /etc/apt/sources.list (or with the command line editor of your choice, sudo nano /etc/apt/sources.list would use nano on the command line without a GUI)
Add the partner repositories by removing the # in front of the following lines (maverick is the version of your Ubuntu installation, it may differ, so use the codename of the release you are using instead of 'maverick'. If you're not sure run lsb_release -c to find out.)
```
# deb http://archive.canonical.com/ubuntu maverick partner
# deb-src http://archive.canonical.com/ubuntu maverick partner
```

Using GEdit to edit the sources.list file

Save and Close.
Resynchronize the package index files from their sources: sudo apt-get update
Official documentation for reference

Solution 2:

The simplest way to enable "partner" repository:

sudo sed -i.bak "/^# deb .*partner/ s/^# //" /etc/apt/sources.list
sudo apt-get update

Solution 3:

CLI method

This method uses

lsb_release -sc to get the Ubuntu (codename) version.
add-apt-repository to alter the appropriate config files.

It has the advantages of working in all versions of Ubuntu.

sudo add-apt-repository "deb http://archive.canonical.com/ubuntu $(lsb_release -sc) partner"

This is from a skype tutorial

Solution 4:

To enable the partner repository from the command line, edit /etc/apt/sources.list:
sudoedit /etc/apt/sources.list and remove the # from the beginning of these two lines:

#deb http://archive.canonical.com/ubuntu maverick partner  
#deb-src http://archive.canonical.com/ubuntu maverick partner

So they are like this:

deb http://archive.canonical.com/ubuntu maverick partner  
deb-src http://archive.canonical.com/ubuntu maverick partner

Then update your apt cache: sudo apt-get update.
