Hello

I am having trouble to install/update any package on julia 0.6  
for example Pkg.update() leads to the following error

```julia
julia> Pkg.update()
INFO: Initializing package repository /root/.julia/v0.6
ERROR: ReadOnlyMemoryError()
 in cd(::Base.Pkg.Dir.##4#6{String,String}, ::String) at ./file.jl:65
 in init(::String, ::String) at ./pkg/dir.jl:47
 in #cd#1(::Array{Any,1}, ::Function, ::Function, ::String, ::Vararg{Any,N}) at ./pkg/dir.jl:28
 in cd(::Function, ::String, ::Vararg{Any,N}) at ./pkg/dir.jl:25
 in update() at ./pkg/pkg.jl:210

```

Any ideas how to solve this ?

I am using ubuntu 16.04 using a virtual machine (Oracle VM) on windows 7

Thanks a lot

PL

The local package repository `.julia/` should be in your home directory. Are you running as root? What is the output of `homedir()`? You should also probably initialize the repository with `Pkg.init()` first.

Thanks for your answer:  
the homedir() command outputs

julia\> homedir()  
“/root”

here is the output for Pkg.init

julia\> Pkg.init()  
INFO: Initializing package repository /root/.julia/v0.6  
ERROR: ReadOnlyMemoryError()  
in cd(::Base.Pkg.Dir.##4#6{String,String}, ::String) at ./file.jl:65  
in init(::String, ::String) at ./pkg/dir.jl:47  
in init() at ./pkg/pkg.jl:70

I guess julia is installed in the wrong place …  
Do you know how I can fix this ?

Thanks a lot

I usually don’t run programs as root and I would not know how to solve it. Can you log in or create a normal user instead?

Then, as a normal user, you could download the [generic Linux binaries](http://julialang.org/downloads/), put them in a local directory and it should work. Also, unless you are an experienced user, you should use the stable release v0.5.1.

I downloaded the binaries and extracted them in my local directory, however I don’t know what to do next …  
I tried to look for some installation or to launch directly julia but not working …

Could launch julia using ./julia in the bin folder, however I have the same problem

julia\> Pkg.init()  
INFO: Initializing package repository /home/plp/.julia/v0.5

I have no idea. Can you cd into `~.julia/v0.5`?
