Someone in my group downloaded Julia 1.6.1 onto a Linux cluster and got a vague error when trying to install any package:

```julia
(@v1.6) pkg> add Flux
 Installing known registries into `~/.julia`
ERROR: could not download https://pkg.julialang.org/registry/23338594-aafe-5451-b93e-139f81909106/437a33d5a2137980d49bc3f6ca85520729877931

```

Confusingly, before showing the error message it showed a **Downloading** progress bar that seemed to be working (it steadily went to 100%). Moreover, running `download("...")` on that URL in Julia succeeds.

How can we get more information on the error? What might be going wrong?

Update: we tried setting `JULIA_PKG_SERVER=""` and got a more informative error message from `git clone` — we were exceeding a disk quota in the `/tmp` filesystem on this cluster. Setting the `TMPDIR=$HOME/tmp` environment variable worked around the problem.

Is there a way to get a more informative error message from the pkgserver-based download?

You could try setting `JULIA_DEBUG=Pkg` or even `JULIA_DEBUG=all`, but no guarantees whether that will be helpful here.
