I upgraded INDI to 1.8.9 and now my Lodestar X2 guide camera crashes INDI as soon as I press connect.
I tried two computers (ARM64 with Armbian Focal, and AMD64 with Ubuntu Focal).  Both with new installations of INDI 1.8.9 - and when I connect the camera in the INDI control panel it causes INDI to crash.

I changed cables.
I tried different USB ports.
I removed all other gear except the Lodestar X2

Nothing stopped the crash,

It as fine two days ago with the previous version of INDI.
Then I connect the camera to my MacBook with an earlier version on KStars (OSX) and it works great - so the camera is not the issue.

Does anyone know how I can get INDI to stop crashing with the SX Lodestar X2 camera?

Works fine here, so it's some build issue with the nightlies. Might be a better idea to compile it yourself.

I am using the last stable release. It only started after upgrading INDI to 1.8.9.
Also, I have no idea what software I need to do that, or what the procedure is.

What would cause this:

How can I go back to INDI 1.8.8? I tried everything today to get 1.8.9 to work with my Lodestar X2 and nothing keeps INDI from crashing when I connect the SX Lodestar. And no one knows why, so I need to go back a version.

Peter,

Have you tried purging indi and then simply reinstalling? That seems to have worked for Jerry:

indilib.org/forum/general/9112-solved-bl...d-cameras.html#68838

The problem may be caused by a failure of the update to synchronize all files, there may be old ones left. By purging indi and then reinstalling, that might fix the problem.

I followed a more complicated route with a similar problem I had with my ZWO-EFW, but in the end it was the complete recompiling of Indi that fixed my problem.

Peter, check out this thread, that might be relevant to you:

indilib.org/forum/ccds-dslrs/9151-asi-us...ails-git-builds.html

Finally got everything working again, after I deleted all traces of KStars and INDI by using the sudo apt-get clean command after purging everything.  Just uninstalling/removing or purging didn't work as every attempt to reinstall from the net just revived the previous version that was on my system.  The clean command fixed that.   Once I installed a clean install everything is working again.   I'm not sure what got corrupted or how.
