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:

```julia
 (@v1.5) pkg> add Plots

```

```julia
(@v1.5) pkg> add Flux
  Resolving package versions...
ERROR: Unsatisfiable requirements detected for package Flux [587475ba]:
 Flux [587475ba] log:
 ├─Flux [587475ba] has no known versions!
 └─restricted to versions * by an explicit requirement — no versions left

```

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

The `pkg> status` yields

```julia
(@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.

`pkg> registry rm General` worked perfectly. Thank you.
