It seems like your basix installation is out of data, as Sobolev spaces was added to basix a month back: https://github.com/FEniCS/basix/pull/589
Thank you I have used the following:
pip install fenics-basix {https://pypi.org/project/fenics-basix/, fenics-basix 0.5.0}
but still the same errors!
To use basix development version, please try:
pip install git+https://github.com/FEniCS/basix.git
Also, which C++ compiler and version are your using?
I think Cmake output could be helpful:

Also, the pip install git+https://github.com/FEniCS/basix.git, didn't help, still the same issues!

@mscroggs Any suggestions?
Following are some files that could help in debugging this issue
To me it seems like the aur/archlinux version of Basix is out of date: https://aur.archlinux.org/packages/fenics-basix-git refers to v0.5.0.post0, while you are trying to install the main branch of dolfinx in your Dockerfile.
I currently do not have access to a computer, so i cannot test what happens if you check out the v0.5.0
release tag of dolfinx after cloning it before installing the C++ layer
checking out v0.5.0
breaks the build much earlier

Note: based on the installed packages, basix 0.5.1.1
is installed and not fenics-basix-git 0.5.0.post0-1
A sidenote that you shouldn't need to build petsc4py
separately, as petsc should provide this: https://aur.archlinux.org/packages/petsc as PETSc has included petsc4py in their repository for the last 2 years: https://gitlab.com/petsc/petsc/-/tree/main/src/binding/petsc4py
Allthough it seems like: https://github.com/FEniCS/dolfinx/pull/2323/files
was not propagated correctly into the v0.5.0
or v0.5.1
release.
@jhale Should we have a patch release with this?
As a side note, you could try using the main branches, as this Dockerfile
works nicely for me:
