Hello, We now have experimental binary packages which support OpenSSL 1.1, which is required for Ubuntu 19.04 "Disco" and the newly-released Debian 10 "buster".
https://www.tarsnap.com/pkg-deb.html#experimental The only real change against 1.0.39-1 is that these allow libssl-1.1, and were compiled against that instead of 1.0.2. You can see all commits which went into this update here: https://github.com/Tarsnap/tarsnap/commits/1.0.39-deb-2 If everything goes well, these should become the non-experimental packages in a week or so. Cheers, - Graham Percival
