Hello,
Unfortunately, you can’t upgrade your FP3 to the last version with automatic upgrade.
That sometimes that have been explained in the footer of weekly development news like here: look for the title OS upgrade info specific to the FP3.
Here is a quote of this section:
- The FP3 OTA OS update from Pie to Q/R is not possible as encryption method changed on FP3 between Pie and Q/R. It is not possible to change the method while updating.
- The team spent a great deal of time on this, but has not been able to resolve this problem. For now, the manual process is the only way to upgrade the FP3 from pie to other OS versions.
I also have a Fairphone 3 bought from the /e/ OS store. I used the easy installer to make an update to the latest version.
This require you to backup all your files before since it will wipe everything !
You can get more information on easy installer here.
