Yes do it this way
the CE Version on my devices could not connect to the CE repo anymore. So kodi takes the last known for good addon normaly stored in addons/packages. But there was an api change also. As a follow up the pvr client is marked as incompatible and will be disactivated.
Relkai has made a change in the nightly Version recently. So use a fresh tar file.
CE can connect to its repo again if you do the procedure as described and will update addons again without problems
