Incomplete documentation: adding additional repositories

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode.

To change the source package that this bug is filed about visit https://bugs.launchpad.net/ubuntu/+bug/1612631/+editstatus and add the package name in the text box next to the word Package.

Which documentation were you reading that was incomplete? The playdeb.net web pages are not something we, the developers of Ubuntu, can fix.

Hi Brian, the documentation that is incomplete is this page from the official documentation for 16.04:

https://help.ubuntu.com/lts/ubuntu-help/addremove-sources.html

Step 4 says " ... enter the APT line ...", which is correct - but the documentation doesn't say anything about adding the repository key. As I said above: "I believe that for non-Canonical repositories (but not PPAs) the user has to add the repository's key. Without the key the command "sudo apt-get update" will give an error message and packages cannot be added from the repository."

Regards,

Chris.
