I upgraded my kstars and indi using the stable PPA today.  I wanted to take some flats using my ASI camera and filter wheel.  The ASI driver crashed, and I found that the version of indi-asi that I have is 1.9~202103012012~ubuntu20.10.1.  indi-asi and indi-asi-dbg are the only drivers shown in an apt search not dated 20210425.

Looking at PPA Listing , I see that indi-asi - 1.9~202104252351 failed to build for all supported Ubuntu versions and most (if not all) architectures.  There are some other drivers which failed to build for some architectures and/or some Ubuntu versions.

Do we have an estimated time for these issues to be resolved?
