We now have updated instructions for installing Clear Containers under Ubuntu and Fedora. [1] [2] 

If you have followed the installation instructions previously, you will need to update your existing apt/dnf files.

For Ubuntu, remove the older apt file as:

rm /etc/apt/sources.list.d/cc-oci-runtime.list

For Fedora:

rm  /etc/yum.repos.d/home\:amshinde.repo


Add the new repository following the updated instructions for your distribution.
