During today I have tried several times to update Julia and I receive the following alert:

```julia

That’s strange, you should have gotten:

Is something sitting between you and the internet and intercepting things?

Does the downloaded file even contain the correct things, for example, what happens if you run:

```julia
using Pkg.PlatformEngines: exe7z
using Tar
open(`$(exe7z()) x "libpng_jll" -so`) do tar
    Tar.extract(tar, "libpng_jll_extracted")
end
@show readdir("libpng_jll_extracted")

What happens if you go to  
[https://github.com/JuliaBinaryWrappers/libpng\_jll.jl/releases/download/libpng-v1.6.38+0/libpng.v1.6.38.x86\_64-w64-mingw32.tar.gz](https://github.com/JuliaBinaryWrappers/libpng_jll.jl/releases/download/libpng-v1.6.38+0/libpng.v1.6.38.x86_64-w64-mingw32.tar.gz) in your browser?

I think you are behind some type of firewall (by [https://www.forcepoint.com/](https://www.forcepoint.com/)) that blocks this download and replaces it with some blocking HTML page.

There is nothing really that the Julia community can do about this, you need to contact the one in charge of the firewall.

Ask your company to not block this. There is nothing anyone here can do.

To put it in other terms, the package manager is like the post-service. However, your company has locked the delivery box so the post-service can’t deliver the package. There is nothing that the post-service can do about that, the company has to unlock the box.

No, it means, you can’t use the internet as you want to. Your organization is prohibiting it.
