It’s difficult to help without more context or details. Could you share the log of the package manager?

Thank you very much for the quick reply. This is what I get when I try to update JuMP:

On a previous try MathOptInterface was updated to 0.9.17, but no luck with JuMP.

Many thanks for your help!

Likely you have something holding DataStructures back at version v0.17. You could show `]st`, and try to look at output of `]add JuMP@0.21.5`.

Thank you very much, Jaakko, that did the trick, it turned out Gadfly v1.3.0 was holding back DataStructures at v0.17, I removed it, updated, and now I am on JuMP v0.21.5, many thanks!
