Dell ubuntu Repositories authorisation Key

Solution 1:

Note: This answer assumes you're running on Ubuntu 16.04, codename xenial. If this is not the case, please edit your post to reflect the version of Ubuntu you are planning to install.

It's much easier to just add these to a sources.list.d file. Run this command:

cat << 'EOL' | sudo tee /etc/apt/sources.list.d/dell-repos.list
deb http://dell.archive.canonical.com/updates/ xenial-dell public
deb http://dell.archive.canonical.com/updates/ xenial-dell-crane-kbl public
deb-src http://dell.archive.canonical.com/updates/ xenial-dell public
deb-src http://dell.archive.canonical.com/updates/ xenial-dell-crane-kbl public
EOL

When you run this, copy and paste all of it. Do not run it line-by-line.

After you're done with the above, run this command:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys F9FDA6BED73CDC22

Finally, run this command to update your package cache:

sudo apt update

Your Dell repos will now be added to your system, and you will be able to install packages freely.
