I have been trying to get Juno up and running on Linux but I can’t seem to be able to build the MbedTLS package. I added the package in Atom and then navigated to ‘Packages’-\>‘Julia’-\>‘Start Julia’. This runs for some time and then I get this out put:

I thought it looked like something was fishy with the Mbed TLS package so I tried to build it from the Julia REPL with Pkg.build(“MbedTLS”) but then I got this error instead:

I am a bit stuck here and any help would be appreciated!

I think [https://github.com/JuliaLang/BinDeps.jl/pull/349](https://github.com/JuliaLang/BinDeps.jl/pull/349) needs to be merged and tagged.
