Also now my ASI174 imaging camera refuses to download images. It works fine in the alignment and focus modules, but refuses to save images in the capture module. Probably a separate issue ...
Btw, I reconbected my guide camera with a new usb2 cable, so that can't be it. And the guide camera works fine in PHD.
The OS btw, is Ubuntu 18.04. Has worked like a charm, and I haven't updated this week yet. Since it all worked flawless yesterday, I don't suspect the OS.
