I am using Julia version 1.5.1 on a Win10 operating system. Trying to add Plots and Flux results in the errors listed below:

 (@v1.5) pkg> add Plots

I have tried the pkg> update and pkg> gc commands as well, but that did not identify any changes.

The pkg> status yields

(@v1.5) pkg> status
Status `~\.julia\environments\v1.5\Project.toml`
  [c3e4b0f8] Pluto v0.11.14

Any suggestions on how to resolve this?

Something is messed up with your registry I think. Try pkg> registry rm General and add again. If that doesn’t work, remove C://Users/.../.julia/registries and try again.
