Below I’ll post a copy of what happens when I try to download IJulia; I can’t attach a screenshot. I can download any package that doesn’t require Conda, but as soon as it requires Conda (as far as I understand, it’s a prerequisite), IJulia doesn’t see it. I tried adding Anaconda to PATH, but it didn’t help. And the IJulia kernel didn’t show up in Jupiter Lab.

Which links failed exactly? The only thing that comes to mind is that maybe you’re behind a firewall that’s blocking some file being downloaded but I can’t think of what it might be. Do you get the same error when just adding Conda?
