When you start INDI from within the Ekos screen, another screen pops up informing you about the status of the connected devices. Go through the tabs there and set the configuration that you want/need. Don’t forget to save the changes which can be done in one of the tabs. Also note that you need to do this for each device separately.

I do not want to sound to harsh but can we get back to my original issue please?
I still cannot see why it does not work.

To recap:
Looks like the solver works with certain pictures but not with some.
It is very strange, I am able to solve an old picture I took with my camera (wide field) a long time ago, but cannot solve a recent picture taken with Ekos through my telescope and Atik CCD.


I do not mind solving on my local machine but it would be nice to get it working remotely too.

From your prior post, you said you had this?
# pwd ; ls
/Astro/Astrometry/indexes
index-4205-00.fits index-4205-02.fits index-4205-04.fits index-4205-06.fits index-4205-08.fits index-4205-10.fits

This is just one index file. On stellarmate, I have this under /usr/share/astrometry:
index-4206-00.fits  index-4206-04.fits  index-4206-08.fits  index-4207-00.fits  index-4207-04.fits  index-4207-08.fits  index-4208.fits  index-4212.fits  index-4216.fits
index-4206-01.fits  index-4206-05.fits  index-4206-09.fits  index-4207-01.fits  index-4207-05.fits  index-4207-09.fits  index-4209.fits  index-4213.fits  index-4217.fits
index-4206-02.fits  index-4206-06.fits  index-4206-10.fits  index-4207-02.fits  index-4207-06.fits  index-4207-10.fits  index-4210.fits  index-4214.fits  index-4218.fits
index-4206-03.fits  index-4206-07.fits  index-4206-11.fits  index-4207-03.fits  index-4207-07.fits  index-4207-11.fits  index-4211.fits  index-4215.fits  index-4219.fits

Index files from 4206 all up to 4219. So you must installed the rest of the index files on the remote machine!

Ok that's enough indexes to solve images in parallel universes. Looks like the problem is confined to Ubuntu on Odroid. I bet if you run the same command on Ubuntu Mate on RPI3, it would probably solve. I've been having recent issues with solving, but they're all relating to solving near the poles which is understandably more challenging. If you have a spare RPI3 around, test that theory at least. Or upgrade to 18.04 if available.

Thanks Jasem I have a spare Raspberry pi somewhere here at home, not a 3.
As for upgrading to 18.04 at the moment I can't and need to wait for the support on the Odroid C1.

Thinking about it, the solving is used really for mount alignment or minor things, and last time I've done I didn't have the right setting in taking the pictures.
As soon as proper darkness is there, maybe a month or so, I shall take more test pictures and try the remote solver(GER) and local server(UK).


The strange thing is that some do get solved and some never get solved, and it can take for ever using the solve-field arguments from Ekos.
As previously said, I can adjust the "field objects" but this isn't something you know in advance I think.

example:

And this one is still on-going...

So now that I am using Ubuntu 18.04 and the latest Astrometry package, I am able to solved the two test pictures.

I will obviously have to test it whenever I snap another picture and use the remote astrometry setup.
