To recommend a user with official /e/OS stabl/e/ and security patch August 5th, 2020 to switch to a UNOFFICAL /e/OS with security patch June 5th, 2020, which is no longer maintained, is not a reasonable solution to the /e/ update problem.
The migration to /e/ OS 8-Oreo 'dev’ has been done long ago, but the e.Team is not able to do this for a stable version yet. For the S9/S9+ a migration to e-0.13 ‘Q’ seems to have succeeded on 29.11.2020 - thanks to preliminary work by the Lineage-Team.
