Build Error: Outdated `roxmltree` dependency in a nested dependency chain

[utkarshdagoat]

While I was trying to build xdg-desktop-portal-luminous for wayshot. I kept getting a cargo build error Following is the output of ninja -C build with CARGO_LOG=TRACE

To check whether the root cause was roxmltree I created a brand new package with same version of roxmltree and could not also build the same.

This is ultimately caused by the following dependency tree:

└─ slint v 1.3.2
    ├── i-slint-backend-selector v 1.4.1
    │   ├── i-slint-backend-linuxkms v 1.4.1
    │       └── i-slint-common  v 1..4.1 
    │                  └── fontdb  v  0.16.2
    │                         └── fontconfig-parser  v  0.5.3
     |                                  └── roxmltree  v  0.18.1

Is there anyway around this or this can be only solved with a dependency update?

PS Tried upgrading slint straight away and didn't fixed it.

I think it maybe a network error. maybe clean the .cargo will fix it

[utkarshdagoat]

I don't think it's a network error as I installed the latest crate of roxmltree in a dummy project and it works fine but in the same project the lower version doesn't work i.e (v 0.18.1).

I have also tried deleting the registry cache which had no effect and the build fails at the same step.

A really stupid question but It can't be that my ip is banned for the lower versions upstream. Right?

I think that's highly unlikely.. Quite the odd situation

[utkarshdagoat]

So I got it to build by directly updating slint to the latest verison 0.4.1 and it works with wayshot.

I think it can be auto updated

Running cargo test in each project doesn't throw any error either.
