Pkg.update() doesn't update

When I run Pkg.update() or update at the package prompt, all I get is:

julia> Pkg.update()
Updating registry at ~/.julia/registries/General
┌ Warning: Some registries failed to update:
│ — ~/.julia/registries/General — registry dirty
└ @ Pkg.API /Users/osx/buildbot/slave/package_osx64/build/usr/share/julia/stdlib/v1.0/Pkg/src/API.jl:157

In particular I know that Atom.jl is at 0.7.11 but I am stuck at 0.7.10. Even if I do add Atom@0.7.11 , it still adds 0.7.10. Nothing else looks like it is updating either.

Looks like it might be the same issue as Registry dirty , so updating to julia 1.0.2 and/or deleting the registries folder may fix it.
