Hello, Marcin, we have now the 6.4 released.
Looking at the 5.4 .spec file it seems that the packaging is very hard for this software... Can't a COPR repo make things less bureaucratic?

There is not much bureaucracy - we would just need a new spec that works on all supported Fedora and EPEL versions and architectures. Testing all that is a several hours effort. It's probably better to invest time and prepare a Dockerfile that does just `apt-get install quantum-espresso` and rely on the DebiChem effort mentioned at https://www.quantum-espresso.org/download:

cat <<EOF > Dockerfile
FROM debian:sid-slim

# Find the version with: apt-cache policy quantum-espresso
RUN apt-get update&& apt-get install -y --no-install-recommends quantum-espresso=6.3-4 quantum-espresso-data && rm -rf /var/lib/apt/lists/*

CMD ["/bin/bash"]
EOF

sudo dnf install -y docker
sudo systemctl start docker
sudo systemctl enable docker

sudo docker build -t quantum-espresso:6.3-4 .
sudo docker images
mkdir storage
wget https://raw.githubusercontent.com/QEF/q-e/master/test-suite/pw_dft/dft1.in -P storage/
sudo docker run -it -v $(pwd)/storage:/mnt --name quantum-espresso_6.3-4 quantum-espresso:6.3-4

mpiexec --allow-run-as-root -np 2 pw.x < /mnt/dft1.in > /mnt/dft1.out
exit

cat storage/dft1.out
sudo docker rm quantum-espresso_6.3-4
