I asked the same question on New to Julia category and just repeat here.

I am trying to install Gtk, but got an error message as below.

ERROR: Unable to automatically install ‘adwaita\_icon\_theme’ from ‘C:\Users\me.julia\packages\adwaita\_icon\_theme\_jll\YjPmX\Artifacts.toml’  
Stacktrace:

I am behind a corporation proxy, but still able to install other packages.  
Does anyone have the same problem?

Can you enclose the error as a [code snippet](https://discourse.julialang.org/t/psa-how-to-quote-code-with-backticks/7530) and share the full stack trace? That way, we will have more information to help you. 🙂

As I understand, the `jll` packages may download blobs from any place on the internet. I don’t remember if package servers also cache the blobs, or maybe the `BinaryBuilder` generated blobs are served from outside the package server. Any of both may cause your proxy to block the request. But without further information is hard to help.

Oh…this is what I got.
