When running install-deps.sh on a Debian system, Ceph relies on ceph-boost. However, ceph-boost currently does not support the RISCV architecture, preventing the install-deps.sh from executing.
I packaged and tested ceph-boost on RISCV using a GitHub action link. The packaged deb also works properly and can be run through install-deps.sh. Therefore, we are considering adding support for hosting ceph-boost's RISCV deb on chacra.ceph.com.
You can see all the build, test, and packaging scripts in the yml file of my github action, link
Feel free to contact me, I'd be happy to provide more information
