Hi Saturne33,
please check your kern.log (ubuntu ==> /var/log/kern.log) and look for the message coming up
As you can see on my log i get a segfault out of libc-2.31.so.
out of /var/log/kern.log Jan 7 17:26:13 kv-XPS-15-9560 kernel: [34344.408379] indi_atik_wheel[25755]: segfault at 0 ip 00007f33b01bab82 sp 00007fff8d9582f8 error 4 in libc-2.31.so[7f33b0059000+178000]
It seems that there was a change in this library since Ubuntu 18.x to 20.x. Maybe a rebuild will help but could also may cause older versions to no longer work.
I would also be happy if someone could come up with a solution.
regards
Klaus

I'm having +/- the same issue ('INDI Driver crashed' from Kstars/Ekos), but with some additional information.
To simplify my tests I did a minimal setup for Ekos:Under Linux Mint 19.3 / Ubuntu 18.04 on my tower PC, it's working perfectly.
- CCD: Starlight Xpress SX CCD
- Filter: Atik EFW (2.2)
Exact same setting under Linux Mint 20 / Ubuntu Focal Fossa on my laptop crashed the INDI driver.
I did a lot of tests: different cables, with or without a USB 3.0 hub, main or battery powered, connection before or after the PC or Kstars.
Results: works consistently on my tower and consistently crashing on my laptop.
I did run the same test using ekos-debugger. Maybe an expert could have a look to the resulting small .txt log files attached.
I'm unfortunately unable to analyse the logs to understand the root of the problem (and even if there are useful information in there).
Also: I have exactly the same .txt file related to successfull attempts on my tower PC, in case it can help.
Can someone help us ?
Best regards
Hi Jasem,
thanks for your reply.
I did a request to the tec support of ATIK...
The answer (see below) was not very helpful.. To connect the filter wheel only will not change the behavior. This will also lead to the segfault..
Anyone who can help me??
Thanks in advance
Klaus
Hi, thanks for your reply....
That was the first thing i had done... Yes it is viewable within USB....
I also tried another usb cable... By the way the error occur even the filter wheel is not connected...
Thanks
Klaus
this is the result for the filter wheel from lsusb -v

Hello i'm new to ekos / indi.
I tried to connect my mount, rotator, camera atik16200 with filter wheel EWF3 (7 Filter) and Lodstar X2 guiding camera with ekos.
Successfully connected was mount, camera atik 16200 and Lodstar X2(guiding camera) and rotator.
The connection to the filter wheel did not work...
I tried to start from console (see following result). First the message that a child process died. After that i add some lines from kernel log
which mentioned a segfault in libc-2.31.so . I'm using an Ubuntu 20.04.1 LTS 64 Bit. I add also a log from ekos session but i didn't see more infos as below written.
Has maybe someone an idea what's going wrong?
Many thanks for any help.
Klaus
