I’m trying to work with the Anaconda developers to iron out some problems with shared-library paths on MacOS ([https://github.com/ContinuumIO/anaconda-issues/issues/6423](https://github.com/ContinuumIO/anaconda-issues/issues/6423)), but they are seeing a weird error (with Julia 0.6.0 on MacOS):
```julia
julia> Pkg.init()
INFO: Initializing package repository /nfs/site/home/opavlyk/.julia/v0.6
INFO: Cloning METADATA from https://github.com/JuliaLang/METADATA.jl
ERROR: GitError(Code:ERROR, Class:Zlib, error reading from the zlib stream)
```
I’ve never seen something like this, so it’s hard to help them; any pointers?

It may, perhaps, be useful to know that I was behind a corporate firewall. Environment variables were set to make the command line `git clone https://github.com/JuliaLang/METADATA.jl` work correctly.

Did you see [https://docs.julialang.org/en/stable/manual/packages/#Packages-1](https://docs.julialang.org/en/stable/manual/packages/#Packages-1) on using `git config` etc? Pkg uses libgit, not the git executable, so environment vars may not work the same way.

I think I’m running into a similar issue running julia from within docker behind a corporate proxy. I have a dockerfile where I can install a bunch of packages, build julia from source, use `curl`, `git clone`, and similar from the command line, but can’t run `Pkg.init()` from within julia without getting the following error:
```julia
INFO: Initializing package repository /pkg/v0.6
INFO: Cloning METADATA from https://github.com/JuliaLang/METADATA.jl
ERROR: GitError(Code:ERROR, Class:OS, Failed to connect to github.com: Connection refused)

```
I have `HTTP_PROXY`, `HTTPS_PROXY`, `NO_PROXY`, and the lowercase versions set, and also tried using the same settings in `git config`. On my development machine this works with just the environment variables set and no global `.gitconfig`.

It’s also worth noting that the official Julia docker images work with only the environment variables defined – I can `export JULIA_PKDIR='/some/other/folder'` and then `Pkg.init()` works fine on both 0.6 and latest. I’m not sure why this is the case.
Edit: this may be related to building from source or running from within the build tree (as required by LLVM.jl) since I can build the official Dockerfiles fine just by adding in the environment variables.

I think this issue can be closed. There were several local issues that I addressed. First, I needed to address [SSL certificate problem](https://stackoverflow.com/a/32476912).
Then, I ran into an obscure ERROR about “packfile trailer mismatch”, which was due to hitting home directory size quota while checking out `METADATA.jl` into `~/.julia/v0.6`.
Once I symlinked `~/.julia` to a local drive with no quota, things started to work as expected.
Thanks for looking at the issue though.
