I have a yakkety system running and would like to do a dist upgrade.
I followed the procedure at https://help.ubuntu.com/community/EOLUpgrades however, it did not help.
Apparently, some files are not found. It looks like the packages at http://old-releases.ubuntu.com/ubuntu/dists/yakkety (and all the other directories) are not available.
Is there a new procedure to upgrade or a manual way to force the system to simply do an upgrade? I basically do not care whether I have to do two upgrades first to zesty and then to artful or to artful directly. However, currently I only have the choice to go to artful directly.
