OTA updater not working, how I fixed

Do you still rememeber …?

This system response sounds to me like the recovery is still not managing the update correctly.

One possibility would be to test whether a manual update is successful:

Download e-1.14-s-20230818321663-dev-bramble.zip. Then boot into the e-Recovery > Apply update > Apply from ADB

Please note:
This is just an idea. I’ve not been running the /e/OS since the above ‘bramble’ OTA update bug and wish that the problem would be solved at the latest with the upgrade to /e/OS ‘T’ in September 2023.
