Here is the whole story :frowning:

Should be fixed.

I don’t understand what was happening. A few minutes later, in the same REPL session, I tried:

(v0.7) pkg> up
  Updating registry at `~/.julia/registries/General`
  Updating git-repo `https://github.com/JuliaRegistries/General.git`
 Resolving package versions...
  Updating `~/.julia/environments/v0.7/Project.toml`
 [no changes]
  Updating `~/.julia/environments/v0.7/Manifest.toml`
 [no changes]

and then add Plots worked as expected:

Something similar happened to me. I was trying to install Flux on Julia 1.0.1 by running Pkg.add("Flux") and it failed due to an unsatisfiable dependencies from Plots:
