Are there binaries available for Debian Buster (10) or do I need to build from source?
We used to provide prebuilt binaries via OBS. However, there were some changes in packaging of upstream stuff (e.g., the gpgme++ library), and therefore our OBS builds are not available for Debian 10 at the moment.
I will appreciate patches which fix this; in the meanwhile, following the docs on a manual build is your best option.
