petsc-dev 3.17.5+dfsg1-1 (riscv64 binary) in ubuntu lunar

 PETSc is the "Portable Extensible Toolkit for Scientific Computation", a suite
 of data structures and routines for the scalable (parallel) solution of
 scientific applications modeled by partial differential equations. It employs
 the MPI standard for all message-passing communication. Several sample
 scientific applications, as well as various papers and talks, demonstrate the
 features of the PETSc libraries.
 .
 This metapackage installs libpetsc-real-dev, which will always depend
 on the most recent version of PETSc with real number support. So if
 you install it then you will get upgrades automatically.
