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