Easily Sign The Ubuntu Code Of Conduct With CoC Signing Assistant

<div style="text-align: justify;"><b>Signing the Ubuntu <a href="http://www.ubuntu.com/project/about-ubuntu/conduct">Code of Conduct</a> may seem difficult, especially for relatively new Linux users so to make things easier, Marten de Vries has created an application called <a href="https://launchpad.net/code-of-conduct-signing-assistant">Code of Conduct Signing Assistant</a> which should make make it easier to sign the Ubuntu Code of Conduct.</b></div><br /><div style="text-align: justify;"><i>You need to sign the Ubuntu Code of Conduct if you want to contribute to various Launchpad projects, upload packages to a Launchpad PPA and so on.</i></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEig-vdDHr7w5xEMYGP1JUe0BAu3iCyZzOngVjte8HKvaWkTu9GDJ8y_FX6AJnHvRfSuIm04aJvK765XR05vFQFUA7oIfHGdcLsPKoGig_nmOpqu2VlkWd8FpMF9dasXwHHaSvi6wTG5vUFh/s1600/ubuntu-code-of-conduct.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="Ubuntu Code of Conduct Signing Assistant" border="0" height="223" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEig-vdDHr7w5xEMYGP1JUe0BAu3iCyZzOngVjte8HKvaWkTu9GDJ8y_FX6AJnHvRfSuIm04aJvK765XR05vFQFUA7oIfHGdcLsPKoGig_nmOpqu2VlkWd8FpMF9dasXwHHaSvi6wTG5vUFh/s320/ubuntu-code-of-conduct.png" title="Ubuntu Code of Conduct Signing Assistant" width="320" /></a></div><br /><a name='more'></a><br /><div style="text-align: justify;">The first Code of Conduct Signing Assistant public version was released recently, so there might be some rough edges, but overall, the application serves its purpose and it's quite easy to use, especially compared to the <a href="http://www.wikihow.com/Sign-the-Ubuntu-Code-of-Conduct">manual instructions</a> of signing the Ubuntu CoC.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">Using the Code of Conduct Signing Assistant is pretty straight-forward, however, there are a couple of things you should be aware of:</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">- On the second page of the Code of Conduct Signing Assistant, you'll have to select a PGP key or create a new one. It's probably better to create the key via <a href="http://www.webupd8.org/2010/01/how-to-create-your-own-gpg-key.html" title="How To Create A GPG Key">command line</a> before starting the Code of Conduct Assistant since you have more options which aren't available if you'll use the Code of Conduct Assistant and furthermore, once you create the key using the GUI, it may seem it didn't work because the application doesn't let the user know he must perform some actions to generate the key (for instance, creating the PGP key from the command line, you'll see a message like the following: "<i>We need to generate a lot of random bytes. It is a good idea to perform some other action (type on the keyboard, move the mouse, utilize the disks) during the prime generation; this gives the random number generator a better chance to gain enough entropy</i>").</div><div style="text-align: justify;"><br /></div><br /><div style="text-align: center;"><a href="http://img.netupd8.com/code-of-conduct-signing-assistant_1.png"><img alt="Ubuntu Code of Conduct Signing Assistant" src="http://img.netupd8.com/code-of-conduct-signing-assistant_1_thumb.png" /></a></div><br /><div style="text-align: justify;">- When you reach "page 7" (screenshot above), you'll have to download the Ubuntu Code of Conduct to your computer, however, the download link doesn't work in the Code of Conduct Signing Assistant window, or at least it didn't work for me so if that's the case for you too, right click the download link, select "Copy link" and copy it to a web browser so you can download the file.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">That's pretty much it, the Code of Conduct Signing Assistant should take care of everything you need to sign the Ubuntu Code of Conduct.</div><br /><br /><br /><h2>Install Code of Conduct Signing Assistant in Ubuntu</h2><br /><div style="text-align: justify;"><b>1. </b>Ubuntu 12.10 and 12.04 users will firstly need to install "python3-gnupg" from a PPA to be able to install this application, because that package isn't available in the Ubuntu repositories. You can <b>download python3-gnupg deb from <a href="https://launchpad.net/~quadrispro/+archive/backports/+packages?field.name_filter=python-gnupg&field.status_filter=published&field.series_filter=">HERE</a></b> (click the arrow next to the package name, then scroll down and click "<i>python3-gnupg*.deb</i>" (I've replaced the version in the filename with "*"), then install it.<br /><br />I didn't link directly to the deb file because if a newer version is uploaded, the link will stop working.<br /></div><br /><div style="text-align: justify;"><b>2. </b>Once you've installed the above dependency, you can <b>add the PPA and install Code of Conduct Signing Assistant in Ubuntu 13.04, 12.10 or 12.04 using the following commands:</b></div><pre class="linux-code"><code>sudo add-apt-repository ppa:marten-de-vries/code-of-conduct-signing-assistant-daily<br />sudo apt-get update<br />sudo apt-get install code-of-conduct-signing-assistant</code></pre><br /><div style="text-align: justify;">Once installed, launch  Code of Conduct Signing Assistant from the Dash / menu and follow the instructions.<br /><br />If you don't want to add the PPA, you can download the Code of Conduct Signing Assistant deb or source code via <a href="https://launchpad.net/code-of-conduct-signing-assistant/+download">Launchpad</a>.</div>

<div style="text-align: justify;">There are various reasons why you may need to find out to which PPA a package belongs to, for instance, in case a package in a PPA breaks something on your system, if you want to install a package which is already installed on your computer on some other machine but you don't know the PPA you've used to install it and so on.<br /><br />So here's a <b>quick tip on how to find out to which PPA a package belongs to. </b></div><br /><a name='more'></a><div style="text-align: justify;"><b>To find out the PPA to which a package belongs to, simply run the following command in a terminal</b>:</div><pre class="linux-code"><code>apt-cache policy <b>PACKAGE_NAME</b></code></pre>replacing "PACKAGE_NAME" with the package you want to find out the PPA for.<br /><br /><b>Example:</b><br /><pre class="linux-code"><code>apt-cache policy oracle-java7-installer</code></pre><br />Here's how the command output looks like:<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh2_uKAYsNzRx6hxpoEVv4NCEnHCZWHDuvQ4lL44RDHhlolzl3tooXX0TtBOxTQ7cEegE5mF83omuih_e0i7UQ8fG30AEbCNBiNUlzF7yo_iZoNX44xwXz6KielTj8TDXowHrVht5H06ARI/s1600/apt-cache-policy-ppa.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="apt-cache pollicy" border="0" height="218" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh2_uKAYsNzRx6hxpoEVv4NCEnHCZWHDuvQ4lL44RDHhlolzl3tooXX0TtBOxTQ7cEegE5mF83omuih_e0i7UQ8fG30AEbCNBiNUlzF7yo_iZoNX44xwXz6KielTj8TDXowHrVht5H06ARI/s320/apt-cache-policy-ppa.png" title="apt-cache pollicy" width="320" /></a></div><br /><div style="text-align: justify;">As you can see, the command output displays the PPA url, which, right after "ppa.launchpad.net" contains the PPA you've used to install the package ("webupd8team/java" in my example above).</div><br /><div style="text-align: justify;">This, of course, also works with packages from the official Ubuntu repositories as well as packages from non-Launchpad repositories. For instance, here's how the output of "<b>apt-cache policy opera</b>" looks like (Opera is installed through its own repository):</div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgBFeMQ2LaWaIwILiWf4dMt70GVC2y4nVZf4ypLOHm4tLwZeeolw5fwkFnNjyVDK1vajxzh8oCekz0fupzy5_PdNXuwagGmwaBaWUImbcOiezAg29TqmvEAdKsBgB19n_13Q50zuS-0qVQ9/s1600/apt-cache-policy-repository.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="apt-cache pollicy" border="0" height="219" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgBFeMQ2LaWaIwILiWf4dMt70GVC2y4nVZf4ypLOHm4tLwZeeolw5fwkFnNjyVDK1vajxzh8oCekz0fupzy5_PdNXuwagGmwaBaWUImbcOiezAg29TqmvEAdKsBgB19n_13Q50zuS-0qVQ9/s320/apt-cache-policy-repository.png" title="apt-cache pollicy" width="320" /></a></div><br /><div style="text-align: justify;">If the repository url is missing, it means you've installed the deb manually, not through a repository (and the package is not available in any repository on your system) or that the repository has been disabled or removed after the package installation.</div>
