I updated this package more than an hour ago:

> **[GitHub - aenarete/KitePodModels.jl: Models of control pods of remote...](https://github.com/aenarete/KitePodModels.jl)**
>
> Models of control pods of remote controlled kites. Contribute to aenarete/KitePodModels.jl development by creating an account on GitHub.

But if I try to install it in an empty project I get an outdated version:

```julia
using Pkg
Pkg.add("KitePodModels")

```

installs version 3.2, not version 3.3

How long can it take until I can install the latest version?

If you run `Pkg.Registry.update()` you should be able to get the latest version afterwards.

Doesn’t help:

```julia
julia> using Pkg

julia> Pkg.Registry.update()
    Updating registry at `~/.julia/registries/General.toml`

I don’t know the answer in general, but you can see what commit of the General Registry the package servers are currently serving based on the contents of `~/.julia/registries/General.toml`. That first line is the tree hash, and the commit with that hash for me currently ([`7a149fdb1`](https://github.com/JuliaRegistries/General/commit/7a149fdb1f802f52633fc1058f4249861a437f65)) is from three hours ago.

It’s usually very quick, but sometimes there can be a delay if e.g. the Pkg Servers are processing some large artifacts, or something like that.

If you need the absolute latest version of the registry, you can set the `PKG_SERVER_REGISTRY_PREFERENCE` environment variable to `eager`, and then do a `Pkg.Registry.update()`. This should almost always give you the latest version of the registry.

Now it works. So about 2h. It can be very fast, but it can also take 2h.

Note that the package servers are now serving a commit from 38 minutes ago. It varies.
