Resolved Sonoma set to release but wants to update to beta on Restart

[haralds]

The title says it all. On one of my systems, Sonoma is set to Release but it wants to update to beta on Restart. I do not want to run betas while traveling. How do I reset the system and delete the pending backup?

CMD-R in the Software Update pane did not do it.

Found the solution:

1. Boot into Safe Mode
2. Open Settings
3. Enable beta updates
4. Close Settings
5. Open Settings
6. Disable beta updates

It cleared the nag. This did not work in normal mode.
