Docker workflow failing

[francesco-ballarin]

Hi @jhale,
the docker workflow seems to have started failing around a week ago, at Build DOLFINx end-user images (arm64, ARM64), specifically at the Build lab step.

The relevant part of the output is

#34 5.349   × Preparing metadata (pyproject.toml) did not run successfully.
#34 5.349   │ exit code: 1
#34 5.349   ╰─> [6 lines of output]
#34 5.349       
#34 5.349       Cargo, the Rust package manager, is not installed or is not on PATH.
#34 5.349       This package requires Rust and Cargo to compile extensions. Install it through
#34 5.349       the system's package manager or via https://rustup.rs/
#34 5.349       
#34 5.349       Checking for Rust toolchain....
#34 5.349       [end of output]

Surprisingly (to me, at least), the amd64 build runs successfully.

Due to this, the dolfinx/dolfinx:nightly tag has not been recently updated. I realized this while testing a downstream library, and started wondering why dolfinx.mesh.MeshTags was not there :O, even though the PR that introduced it was merged a couple of days ago.

There is an issue in the arm images, namely that y_py does not have an arm wheel. Should be resolved by y-crdt/ypy#115

Now moved to: y-crdt/ypy#119

Fixed in upstream package.
