Comment (by Schamschula):

 Actually, even a left over version of {{{py36-erfa}}} won't work, as
 {{{py-erfa}}} and {{{erfa}}} have to be the same version and {{{erfa}}}
 has been updated to version 2.0.0.

 There is no way of predicting when {{{py-astropy}}} will drop support for
 {{{py-erfa}}} < 2.0.0. It is best to remove py36 support for {{{py-
 astropy}}}.
