Hello everyone,

I need some help.  
I’m on windows 8 and I just installed JuliaPro 0.6.2.2  
I cannot install any package. For now I only tried with YAML, Plots and Cubature and none of them work.

They all give the same error:

```julia
julia> Pkg.add("Cubature")
INFO: Cloning cache of Cubature from https://github.com/stevengj/Cubature.jl.git
ERROR: Cannot clone Cubature from https://github.com/stevengj/Cubature.jl.git. user cancelled certif

N) at .\pkg\entry.jl:30
(::Base.Pkg.Entry.##1#3{String,Base.Pkg.Types.VersionSet})() at .\task.jl:335

```

The error looks similar to the one discribed in [this topic](https://discourse.julialang.org/t/juliapro-6-0-1-cannot-add-plotting-package/5282) except that in my case it’s not Plots specefic.

Many thanks in advance

Sorry,  
I realized this must be a duplicate of [Git / Pkg Error](https://discourse.julialang.org/t/errors-for-git-pkg/9351).
