Hey Peter,
thanks for this hint. The good news #1 is: The package can be installed in this way. The good news #2 is: I can start indi_atik_ccd and it talks to my camera. The bad news is: This confuses the package manager and apt-get becomes virtually useless. So, this is only a solution for a short time.

Will make more tests tomorrow night or so. Maybe I will terminate my Ubuntu adventure and go back to Raspian and build everything from scratch.
Best Regards
Andy

Peter, Debian in all their collective wisdom, decided to rename the library to libcfitsio2, it's still cfitsio v3 but the SO name is 2 now, don't ask me why.

Great, it seems, that I'll remove this dependency from the driver and will rely on that it is installed anyway on machine with INDI Peter

can you make the dependacy 2 or 3 ? I've never taken a close look at how debian specifies dependancies, but the systems I have worked with give the option to make it depend on one or the other, and installation will drag along whichever is available.

To be honest I don't know. But dependency on the package name is not an issue, some cfitsio is definitely present on the system if INDI is installed. What can be a problem is if .so library has a different name. Peter

I just wanted to let the community know the latest status on this:
(1) The wrong library name is an official debian bug - no idea when they will fix it.
(2) I removed the dependency from the package
(3) Created a symbolic link for libcfitsio3 for dynamic linking
-> Picture taking works fine now.
Let's see what happens when the bug is corrected...
Thanks to everyone for their answers.

I confirm this issue.
Ubuntu 15.10 is distributed with libcfitsio2, which contains libcfitsio.so.2 and not libcfitsio.so.3
Quick fix is to run # ln -s /usr/lib/arm-linux-gnueabihf/libcfitsio.so.2 /usr/lib/arm-linux-gnueabihf/libcfitsio.so.3
This however does not fix apt-get inconsistency. Which is pain for any update.

Peter, I believe that removing this dependency from the driver is the best idea. The driver itself should require libindi1 only. All the other dependencies are indirect and are applicable to libindi1, not atik_ccd.

Yes, I'll do it in next version. Peter

Peter, the dependency problem still exists in atikccd 0.47.
Please put it on your CR list for the next version.

Sorry, you're right. Try 0.48: download.cloudmakers.eu/atikccd-0.48-v7-armhf.deb

Solved! Thanks a lot.

I just compiled v4 (nasa warn of a critical bug fix) and symbolic linked the cfitsio (and v3) to v4.

I noted that on the standard ubuntu 15.x desktop install that it's v2 hence the deb package still gives the same issue.
