Artifact hash mismatch when installing libpng (Julia 1.6.1)

General Usage

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

How to proceed?

If you do:

download("https://github.com/JuliaBinaryWrappers/libpng_jll.jl/releases/download/libpng-v1.6.38+0/libpng.v1.6.38.x86_64-w64-mingw32.tar.gz", "libpng_jll")

using SHA
open(sha256, "libpng_jll") |> bytes2hex

what does it say?

julia> download("https://github.com/JuliaBinaryWrappers/libpng_jll.jl/releases/download/libpng-v1.6.38+0/libpng.v1.6.38.x86_64-w64-mingw32.tar.gz", "libpng_jll")
"libpng_jll"

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:

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")

julia> using Pkg.PlatformEngines: exe7z

julia> using Tar

julia> open(`$(exe7z()) x "libpng_jll" -so`) do tar
           Tar.extract(tar, "libpng_jll_extracted")
       end

So you are getting a bad file somehow, what’s its size?

julia> filesize("libpng_jll")
526536
7 
filesize("libpng_jll")
1969
8

Anything readable in it?

julia> read("libpng_jll", String)

read("libpng_jll", String)

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 in your browser?

I think you are behind some type of firewall (by 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.

There’s a solution?
What to do?

14

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.

Short question, does it mean that I can’t use Julia?

16

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

17

And how to update the packages?

18

Without a working Internet connection?

19

This.

In julia 1.5.4 everything works fine from the same PC !!! ???
