I had the same `GLIBC_2.38' not found' error when I upgraded my beta today. Also on bookworm; running on a Pi 4. Sorry, I can't now be certain of the "old" and "new" domoticz releases.
I "fixed" the problem by reverting to an older version of the bata, as described at https://wiki.domoticz.com/Raspberry_Pi# ... ect_update
It's now running OK on version 2025.2 (build 17057)
My impression from a few searches is that Glibc 2.38 is used in trixie but not in bookworm. But I'm not an expert!
I hope this helps.
Should be solved now by upgrading to the latest beta.
The build servers had to be adjusted because of a big (&$!@) change by mosquitto's CMake project.
Domoticz is now also using a new external library (libmosquitto1) that is installed by the updatebeta/updaterelease scripts (assuming you are on one the latest beta's)
For users running a stable release via the bash install command line , you should run this script again so all dependencies are installed.
Of course docker users will have no issues when upgrading
