control: reopen -1 control: merge -1 828267 from the change [0] you use say that a compatible API is used but the CFLAG change makes no sense. This is probably a miss understanding. You have two choices: - port (or let port) the software to use libssl-dev which provides the openssl 1.1.0 API and be done with it. - use libssl1.0-dev instead which will pull in the openssl 1.0.2 library and you get your package into testing for the Stretch release. Then you can finish the transition (to 1.1.0) in the Buster cycle.
