The update is not directly downloadable.
Users can sign up for the Beta Labs to get it before other Nokia 6 users.
The update brings some significant bugs fixes.
After Nokia 5, the Nokia 6 has set foot in Beta Labs to taste an update of Android 8.0 Oreo.
To upgrade it, you need to sign up for Beta Labs, and it’s not yet publicly ready for use. This will support HMD to squash any bugs before the software goes live. The people who register are likely to be tech-canny and aren’t gripped by fear of the occasional issue.
Here is the short video uploaded by Juho Sarvikas (A Chief Product Officer, HMD Global – Home of Nokia Phones).

If that’s you, sign up here and receive Oreo much earlier than other Nokia 6 users.
