apt update -y
apt install -y fenicsx git python3-adios2-mpi python3-pip python3-pytest
pip show fenics-dolfinx

# Version: 0.7.3
mpirun --version
# prints

git clone https://github.com/jorgensd/adios4dolfinx.git
cd adios4dolfinx
git checkout v0.7.2
pip install --break-system-packages .

@drew-parsons we will have to hold off a bit longer to package adios4dolfinx, because buildd will surely fail.

v0.7.3 released (and is soon on pypi). It fixed the issues for me at least. Feel free to reopen if you discover any issues @francesco-ballarin.
