Pop 18.04 includes a new recovery system feature. If you would like this new feature, please reinstall the operating system as described here: Install Pop. Future upgrades will update the recovery partition enabling more reliable upgrades. The recovery partition also provides a live environment that helps speed up diagnosing and fixing support issues. Upgrading in place will not create a recovery partition.
