- drop 'all' architecture from matrix (which wasn't even an ARCH to begin with)
- move repo creation out of matrix and into the merge/publish job
- build source packages only on riscv64 and not on the slower ARCHs
- general streamlining / avoid duplication (closes: #16)
- let reprepro do the heavy lifting and publish the pool and dists
directories
- don't publish conf and db directories as they might contain contain
sensitive data
- sign with Armbian community GPG keys for security
- force overwriting of older artifacts
- in the future we might want to import the current repository and
keep around the latest three versions of a package
- we are currently recreating the entire repository from scratch
no real compilation of actual source code is taking place so this
ought to be no issue
- make sure reprepro is installed in the container
- reprepro configuration resides in debian/artifacts/conf directory
- drop the by-now unnecessary step to mkdir debian/artifcats
- publish sources and binaries
