julia error when using Pkg.add

Question

I just install julia in ubuntu and found some problems when I added a package.

julia> Pkg.Add("Gadfly")
ERROR: UndefVarError: Add not defined

I also tried to update julia but an error popped up:

julia> Pkg.update()
INFO: Initializing package repository /home/jing/.julia/v0.5
INFO: Cloning METADATA from git://github.com/JuliaLang/METADATA.jl
fatal: unable to connect to github.com:
github.com[0: 192.30.252.131]: errno=Connection timed out

ERROR: failed process: Process(git clone -q -b metadata-v2 git://github.com/JuliaLang/METADATA.jl METADATA, ProcessExited(128)) [128]

in anonymous at pkg/dir.jl:52
in cd at ./file.jl:22
in init at pkg/dir.jl:50
in cd at pkg/dir.jl:28
in update at ./pkg.jl:45

Could anyone please help me fix this problem? Thanks!!

The key message here is

fatal: unable to connect to github.com:
github.com[0: 192.30.252.131]: errno=Connection timed out

It seems you didn't have an internet connection when this was run. Make sure you have internet and that you can access github on the machine this is running on.
