When I try to install a package on my personal computer, where I have v1.7.3, everything is fine.
When I try it in our cluster for v1.7.3, I get the below error. This is the case for even older versions (v1.3, v1.5), which used to work just fine.
On my personal computer I have curl version 7.92 and on the cluster it is a rather old version, 7.72.
I went through the Julia code, and it seemed to me that it requires curl \>7.84.
Could the reason for the below error be that the package manager require curl \>7.84?

Julia bundles it’s own copy of curl, but I think it could be the cluster is configured to use system curl instead. There’s some discussion in this issue: [Error: curl\_easy\_setopt: 48 · Issue #149 · JuliaLang/Downloads.jl · GitHub](https://github.com/JuliaLang/Downloads.jl/issues/149#issuecomment-1068097086)

Thank you!
By checking the link, I could get rid of Error 48. But still have others.
Better to pass the task over our system admin I think 🙂
