uber-juno install fails in atom release 1.40

[rryi]

System: Win10 x64 2019H1. Atom setup via ZIP file (portable installation)

I did install uber-juno in older atom releases, up to release 1.39.1, without problems.

In release 1.40, I get the error

Juno: Error installing package julia-client

Error: Installing “julia-client@0.9.4” failed.

I tried then to install julia-client, only.

It fails, displaying Installing “julia-client@0.9.4” failed.Show output…

the output:

May be related--I just updated Atom to 1.40.0 (from ~1.28 I think) and the Juno elements disappeared. Tried uninstalling and reinstalling Juno and no luck. No error, packages show as installed, just no Juno UI.

UPDATE: Nuked Atom (deleted .atom directory, fresh install), and tried to install uber-juno. Same error as OP.

UPDATE 2: Downgrading to 1.39.1 allows installation to complete automatically.
