For linux I used this channel: Gfortran :: Anaconda.org
Just re-checked and indeed saw the following during installation:
The following NEW packages will be INSTALLED:
gfortran conda-forge/linux-64::gfortran-12.2.0-h8acd90e_11
gfortran_impl_lin~ conda-forge/linux-64::gfortran_impl_linux-64-12.2.0-h55be85b_19
libgfortran5 conda-forge/linux-64::libgfortran5-12.2.0-h337968e_19
Honestly I did not pay attention before to the ‘impl’ package… have to dig deeper on that one
