On my Windows Machine I tried updating both Revise and JET. There is an interesting error that I cannot figure out. This is on Julia 1.12.6. It does not occur on my RPI 4 with the latest OS and Julia 1.12.6.

You can see that both Revise and JET are not the latest versions. Update gives an error which I cannot figure out.

If I remove Revise and then add it, it adds the same version again. If I try to add it with the URL, it complains about a compat issue. If I remove LoweredCodeUtils, by deleting it from the package folder, the same older version comes back.

Anyone know what is happening?

The two errors tell most of the story:

- The first says that your General registry cannot be updated and is likely out-of-date, so Julia is not aware of the latest package versions and their various (in)compatibilities
- The second says that something in your environment (the answer is JET) supports LoweredCodeUtils version 0.1 through 3.5.3, and you’re trying to install the master branch of Revise which requires LoweredCodeUtils 3.7 or higher.

So let’s check the package compatibilities:

- [Revise.jl/Project.toml at b2597a0c1cb95405b17712ad1511b0b147eb8778 · timholy/Revise.jl · GitHub](https://github.com/timholy/Revise.jl/blob/b2597a0c1cb95405b17712ad1511b0b147eb8778/Project.toml#L27) (applies to you since you’re trying to install directly from the master branch on GitHub)
- [JET.jl/Project.toml at 9bc9057b1c257b8905e8c8b4d888c88cc89e9378 · aviatesk/JET.jl · GitHub](https://github.com/aviatesk/JET.jl/blob/9bc9057b1c257b8905e8c8b4d888c88cc89e9378/Project.toml#L36) (JET 0.11.5) should support LoweredCodeUtils 3.7 (it requires 3.6.2 _or higher_). But notice that you have JET 0.11.3, and older versions had an explicit cap: [General/J/JET/Compat.toml at 6321655ce2b205274a99274b23da074bc9a152a5 · JuliaRegistries/General · GitHub](https://github.com/JuliaRegistries/General/blob/6321655ce2b205274a99274b23da074bc9a152a5/J/JET/Compat.toml#L99-L106)

The one thing that doesn’t quite make sense to me is that those bounds appear to apply to 0.11.4 but not 0.11.3 (a little higher up in that last Compat.toml file). But since your registry is out of date, it’s possible this is something that changed over time.

You might be able to add JET 0.11.5 manually the same way you’re trying with Revise, but honestly I’d focus on trying to figure out why your registry won’t update.

I did `] registry rm General` and then tried to add General again with a similar error.

```julia-auto
(@v1.12) pkg> registry add General
ERROR: could not download https://pkg.julialang.org/registry/23338594-aafe-5451-b93e-139f81909106/e7833696bb8a3a65ffebfa27e13ab28b2d0d2640
Exception: RequestError: HTTP/1.1 302 Moved Temporarily (Failed to connect to storage.julialang.net port 443 after 2035 ms: Could not connect to server) while requesting https://pkg.julialang.org/registry/23338594-aafe-5451-b93e-139f81909106/e7833696bb8a3a65ffebfa27e13ab28b2d0d2640

```

I then took the URL it is requesting and copied it into my browser. It asked to save e7833696bb8a3a65ffebfa27e13ab28b2d0d2640.tar.zst. When I okayed that and went to look at the download it had not started, so I went to write this post. After starting this post, I went back and found it had downloaded. So I think my error is a timeout.

Can I take this downloaded file and move it somewhere (~/.julia/registries) where it is recognized? Do I need to extract it and recompress with the name General.tar.gz? Or can I increase the timeout when I do `] registry add General`?

Here is some code I used to disable the timeout mechanism. I don’t  
know if there is a simple way to do this now…

```julia
using Downloads, Downloads.Curl
Downloads.EASY_HOOK[] = (easy, info) -> begin
    # Disable LibCURL's low speed timeout
    Curl.setopt(easy, Curl.CURLOPT_LOW_SPEED_TIME, 0)
end

```
