Hi Andreas, Conda should not enter the main section.
As doko said, conda use MKL (non-free) by default, and prebuilt packages are linked against libmkl_rt.so (entrance lib of MKL). So if you are going to do performance tests, swithing BLAS/LAPACK alterntive to libmkl_rt for Debian packages could help you reduce the number of variables to control. Install an Anaconda instance and identify the MKL linkage: fdfind -e so -x readelf -d | rg mkl Another point supporting the "should enter contrib" claim is that Anaconda does NOT allow its software repository be mirrored without asking, which makes the packages not freely redistributable.
