I was trying to update from e-1.6-r-20221202239576-dev-FP3 to e-1.6-s-20221201239247-dev-FP3 by sideloading but ran into this error:

Update package is older than the current build, expected a build newer than timestamp 1669966361 but package has timestamp 1669872012 and downgrade not allowed

To avoid bricking, I did not proceed.
I checked the timestamps and those fit the dates in the version strings.

Is it safe to install this anyway?
This method is generally what your manual upgrade procedure on the website suggests to do, there is just no mention of this error. I suppose it’s because the 1.5-s branch was released later than 1.5-r so it just didn’t come up last time.
