Thank you for contacting us.

I've been using Xubuntu 20.04 and INDI 1.96 very stable.

ASI120MC was also used without problems.

I think that the cause of this trouble is the change in the connection method of the optical train and the driver added after 1.96 that I was using.

This time, after a clean installation of a total of 4 systems, 3 MINIPCs and RaspberryPi4ARM64, when I rebuilt, I was able to connect all the devices I owned, but it was not very stable.
INDIWeb Manager -> CCDCiel and the connection that bypasses the optical train no longer cause instability.
I'm guessing that a looping phenomenon occurred when connecting.

My connection was stable, but I started having tracking issues with AZGTi, which is also being talked about on the forums.

It feels like there is a bug compared to the previous version.

It would be more stable if all dependencies were packaged like the Mac version. . .

It's been 7 years since I switched from ASCOM, which I used for 10 years, to INDI.
Once the environment is in place, it is a very stable and good environment, but there are regular connection problems. . .

I guess I was unlucky this time. . . .
