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:

• CCD: Starlight Xpress SX CCD
  
• Filter: Atik EFW (2.2)

Under Linux Mint 19.3 / Ubuntu 18.04 on my tower PC, it's working perfectly.
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
