Thanks Aaron,

Did you re-build Gnuastro from source after installing libgit2 with apt?

It would indeed be good to be creative, and such feedback is indeed very
valuable. The Conda suggestion was just to avoid such issues causing
delays in your main work and since you mentioned some dependencies from
Conda ;-).
Personally, I always build Gnuastro and its mandatory dependencies from
source myself and don't rely on any package manager (as described in
[1]): there are so many configure-time options that they can benefit
from. For example simply adding CFLAGS="-g0 -O3" to the configure script
will speed them up due to increased compiler optimization features (that
are usually not enabled by package managers), or things like CFITSIO
that need a configure-time option to access a FITS file in parallel and
has CPU-specific optimizations (see [2]).
Cheers,
Mohammad
