[Bill Allombert]

Package: python3-petsc4py
Version: 3.12.0-8
Severity: important

Hello Debian Science Maintainers,

There is a circular dependency between python3-petsc4py, python3-petsc4py-64-complex, python3-petsc4py-64-complex3.13, python3-petsc4py-64-real, python3-petsc4py-64-real3.13, python3-petsc4py-complex, python3-petsc4py-complex3.12, python3-petsc4py-complex3.13, python3-petsc4py-real, python3-petsc4py-real3.12 and python3-petsc4py-real3.13:

python3-petsc4py 	:Depends: python3-petsc4py-real, python3-petsc4py-complex, python3-petsc4py-real3.12, python3-petsc4py-complex3.12
python3-petsc4py-64-complex 	:Depends: python3-petsc4py-64-complex3.13
python3-petsc4py-64-complex3.13 	:Depends: python3-petsc4py (>= 3.12.0-5~)
python3-petsc4py-64-real 	:Depends: python3-petsc4py-64-real3.13

python3-petsc4py-real3.13 	:Depends: python3-petsc4py (>= 3.12.0-5~)

Complex circular dependencies are known to cause problems during upgrade, so we
should try to avoid them.
