Robostack-humble channel not mirroring correctly

[TedVanderfeen]

Checks

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pixi, using pixi --version.

Reproducible example

pixi init robostack
cd robostack

Modify pixi.toml with the following configuration:

[project]
name = "robostack"
version = "0.1.0"
description = "Development environment for RoboStack ROS packages"
authors = ["Your Name <your.email@example.com>"]
channels = ["https://fast.prefix.dev/conda-forge"]
platforms = ["linux-64", "win-64", "osx-64", "osx-arm64", "linux-aarch64"]

[target.win-64.dependencies]
#vs2022_win-64 = "*" #Uncomment if using Visual Studio 2022

[dependencies]
python = "==3.11"
compilers = "*"
cmake = "*"
pkg-config = "*"
make = "*"
ninja = "*"

[environments]
noetic = { features = ["noetic"] }
humble = { features = ["humble"] }
jazzy = { features = ["jazzy"] }

#noetic
[feature.noetic]
channels = ["https://prefix.dev/robostack-staging"]

[feature.noetic.dependencies]
ros-noetic-desktop = "*"

#humble

#jazzy
[feature.jazzy]
channels = ["https://prefix.dev/robostack-jazzy"]

[feature.jazzy.dependencies]
ros-jazzy-desktop = "*"

rosdep = "*"

pixi install
pixi shell -e humble -v

Issue description

I'm currently updating the documentation (RoboStack/robostack.github.io#73) for https://github.com/RoboStack/ to include install steps for Pixi and the new robostack-(distribution) channels. But it looks like there's an issue with the https::/prefix.dev/robostack-humble channel. I get the following error upon invoking pixi shell -e humble -v. Tested on both Linux/WSL and windows to the same effect.

ted@SCYTHE-PH:~/robostack$ pixi shell -e humble -v

ros-humble-desktop installs fine when grabbing files from https:://prefix.dev/robostack-staging, and also installs correctly into a mamba environment from the conda channel robostack-humble.

Expected behavior

Expect the environment to grab all dependencies without issues.

[traversaro]

I am not super-familiar with how channels are overridden in features, but if feature-specific channels overrides the project specific one, perhaps we should have channels = ["https://fast.prefix.dev/conda-forge", "https://prefix.dev/robostack-humble"] under [feature.humble]? However, if jazzy works fine perhaps this is not the problem.

We were able to reproduce, there seems to be indeed a mirror issue on prefix.dev. We'll look into it.

This should be fixed :D
