After some success with Ekos, i'm trying to switch from a mac to a Raspberry Pi running ubuntu 21.10. I think I need a recent Ubuntu get libraw20 to support CR3 raw files generated by me EOS R. Mostly looks good but plate solving, and thus the polar alignment tool, are failing on the Pi but are fine on the mac - well almost.
The solver will capture and solve and polar align fine on the mac, but fails on the pi. Seems to capture fine, but fails to solve. I'm using the internal solver. Same configuration on both mac and pi with same index files loaded.
The solver will load and slew fine on the mac from .CR3 raw files, but not from .fits files captured by indi/ekos using the camera module.
Load and slew on the Pi does not see .CR3 files, only .fit(s) files.
Load and slew on the Pi will solve .fit files created by Siril by converting from .CR3 files but will not solve .fits files captured by indi/ekos
I have two test images in three flavours so that I'm testing the same underlying image in different situations. The images are laptop-1 and laptop-2 and the variations are: the original raw file from the camera card, the .fits files captured by the Ekos camera module, and the .fit files created by converting from the original raw files using Siril. The images were captured using the mac. Sadly I don't have any images captured by the Pi in raw .CR3 format.
There is possibly more than one thing going on here. Key may be the fact that if the camera module captures an image and stores it as a CR3 raw file, the file will plate solve with load and slew, but if it converts and stores it as a .fits file load and slew fails. Doesn't crash - the solver just fails to find a solution.
My real issue, which is to get polar alignment working on the Pi may be related or may be something else. The load and slew issue can be bench tested. Any help would be greatly appreciated.

I can't find the log files! So two console logs - first a successful solve of a CR3 file and the failing of its .fits equivalant. The console logs are in reverse order.
