Is it only my  opionion or alla versions  greather  than Kstars 3.5.2. are all  with problems  with some stuffs???? I tried  allora the versions  with the same  hardware, bug i have always problems. Eqmod ,QHY, DMK, CEM70 WEATHERRADIO, guiding algorithms  etc 

Did you upgrade INDI? You need version 1.9.1 for the latest version of kstars.

Yes the system wss updates with the APT dist-upgrade command

Am I the only one that have all these issues???

Could you please be more specific? A log file and a crash dump would be very helpful.

I‘m running 3.5.4 and it’s working fine. But I switched with the EKOS client from RPi to an Intel NUC since I got out of memory exceptions. This is due to the fact that a 32bit OS isn’t sufficient meanwhile even for medium size chips like a ASI 1600mm.

Actually I do not have any log because I am out to take as much signal that I can, and I can't waste time to make tests.
So I started my system upgraded from 3.5.2 to the latest 3.5.4 from Astroberry repos, with my QHYCCD183M, CEM70, DMK618, Arduino focuser on a Rasp 4GB.
This is not the first time that I have (and also my friand with an EQ6) problem with versions greather than the 3.5.2, so I replaced the SD card with the 3.5.2 and all works.
