Problem adding packages

General Usage
1

Hello, I am having this error while installing different packages. I do not understand what the problem actually is. It does not happen with all the packages. It happens with NLopt and when adding Distributions, with an artifact (?) called OpenSpecFun.

(@v1.6) pkg> add NLopt
