CMake Error at scripts/cmake/vcpkg_download_distfile.cmake:32 (message):

  Failed to download file with error: 1
  If you are using a proxy, please check your proxy setting. Possible causes are:

  1. You are actually using an HTTP proxy, but setting HTTPS_PROXY variable
     to `https://address:port`. This is not correct, because `https://` prefix
     claims the proxy is an HTTPS proxy, while your proxy (v2ray, shadowsocksr
     , etc..) is an HTTP proxy. Try setting `http://address:port` to both
     HTTP_PROXY and HTTPS_PROXY instead.

  2. If you are using Windows, vcpkg will automatically use your Windows IE Proxy Settings
     set by your proxy software. See https://github.com/microsoft/vcpkg-tool/pull/77
     The value set by your proxy might be wrong, or have same `https://` prefix issue.

  3. Your proxy's remote server is out of service.

  If you've tried directly download the link, and believe this is not a temporary
  download server failure, please submit an issue at https://github.com/Microsoft/vcpkg/issues
  to report this upstream download server failure.

how to solve this problem?

[Osyotr]

#37839

[gracicot]

Is it possible to create a new tag for vcpkg with liblzma downgraded? I'm currently waiting on a tag to upgrade vcpkg on nixpkgs.

[dg0yt]

Just choose a commit you trust. AFAICT tags have no meaning with regard to maturity here. They are updated so that nobody downloads even older tags.
And of course if users don't have a historical xz-utils tarball already, reverse dependencies of liblzma won't build.

[jimwang118]

@zhang49 Can you successfully install opencv2 after updating the vcpkg library?

[rezzeted]

@dg0yt The official xz repository has been turned off. Is it possible to have a temporary solution for the vcpkg maintainers to accept the path to use the bminor/xz mirror repository?

[dg0yt]

@rezzeted I'm only a community member... You would better ask in the PR which rolled back the port version (#37841).

If the SHA512 of the other repo matches, you can prefetch the tarball and put it to a local asset source or the downloads directory.

Hello,
Any solution ? There are a lot of closed issues that point to #37893 , but I see no solution here.

This is exactly what is done here: (#37839 (comment)).

You have to not only reinstall the library as explained in the above link but also

1. clear the vcpkg cache ( on windows this is to delete C:\Users<your-user>\AppData\Local\vcpkg\archives - on other platforms please search the internet )
2. in VCPKG_ROOT\buildtrees\versioning_\versions\liblzma<any guild> update the file as explained in the link from above ([liblzma] port uses compromised version #37839 (comment)).

[Baklap4]

Within a CI/CD/GH-actions situation you can't easily change or patch files.. i'd love to see a commit in here where the mirror is changed to a working one

[jimwang118]

The issues that are closed are the same issue as it, so the others are closed and only this one is kept for tracking.

[dsvensson]

It would be great if the freeimage port gained a feature flag to disable the transitive lzma dependency of tiff. Lots of projects can probably survive without it.

The file is available here

https://sourceforge.net/projects/lzmautils/files/xz-5.4.4.tar.gz/download, but it cannot be installed manually due to a different hash

cc @JavierMatosD @BillyONeal, can we switch to this URL https://sourceforge.net/projects/lzmautils?

This has affected our organizations development workflow significantly. Pending a permanent fix, here is a rudimentary patch that seems to work for the most part:

1. Download a tarball of xz v5.4.4 - this is the one vcpkg is currently using, seeing as subsequent versions contain a backdoor. I downloaded mine from the Internet Archive's Wayback Machine. Link: https://web.archive.org/web/20240329183646if_/https://codeload.github.com/tukaani-project/xz/tar.gz/refs/tags/v5.4.4
2. Rename the file to tukaani-project-xz-v5.4.4.tar.gz
3. Place it in <vcpkg_root>/downloads (e.g. C:\vcpkg\downloads)
4. Clear the z_vcpkg_download_distfile_show_proxy_and_fail function in <vcpkg_root>/scripts/cmake/vcpkg_download_distfile.cmake so that it does nothing. From what I have observed, this change seems to be harmless since even if a download does fail it will still eventually error since it cannot find the file for extraction. However, by emptying this function, this bypasses the error caused by not being able to download the xz source tarball.

I haven't been able to figure out how to implement this in our CI/CD solutions, but this serves as a functioning rudimentary patch.

#37841 (comment) The repo should be public again.
