Hi Tim,

Thanks for the test. Your findings indicate that the hack does not work, clearly too much has changed in the library interface.

If you have not already done so you can revert the hack fully with these commands :
At this point I see only three remaining paths forward:

1. github.com/rkaczorek/astroberry-server/i...suecomment-828265566 . This is a lot of work and not all RPI will have the needed working space for it.
2. manually backport the needed libraw20 changes into libraw19 and create a new so.19 library . Noone has done this yet to my knowledge.
3. wait for raspbian to upgrade to a newer debian release
