I don’t have enough context from your report. Somehow, I think, that “diskuv-opam-repository” was removed from that switch?

Your switch should be using https://github.com/diskuv/diskuv-opam-repository/tree/main/packages/core/core.v0.16.1%2Bmsvc%2Br1

The homepage https://github.com/diskuv/diskuv-opam-repository shows the command to re-add it: opam repository add diskuv-2.0.2 --rank 1 'git+https://github.com/diskuv/diskuv-opam-repository.git#2.0.2'

Then try your opam install again

Also, can you run opam repository and paste the output here? Thanks!

I tried to implement your suggestion, but still reported the same error

The homepage https://github.com/diskuv/diskuv-opam-repository shows the command to re-add it: opam repository add diskuv-2.0.2 --rank 1 'git+https://github.com/diskuv/diskuv-opam-repository.git#2.0.2'

This is what you want:

[NOTE] These are the repositories in use by the current switch. Use '--all' to see all configured repositories.

<><> Repository configuration for switch playground <><><><><><><><><><><><><><>
 1 diskuv-2.0.2 git+https://github.com/diskuv/diskuv-opam-repository.git#2.0.2
 2 default      https://opam.ocaml.org

Thanks!!

Okay, there was an issue with the tag on 2.0.2.

Do the following to get the update:

opam update diskuv-2.0.2

and then redo:

opam install --switch playground core

(In my test I had to do the last command twice)
