I'm trying to install XMailer from the repository via the Online Package Manager. Synapse is a dependency, and the installer is successful in downloading, opening, and compiling that package. Xmailer, however, fails with a "Fatal: Cannot find SSL_OpenSSL used by XMailer of package XMailerPkg." I'm running Ubuntu 19.04 and ensured that I had openssl and libssl-dev (1.1.1b-1ubuntu2.4) installed before attempting to install XMailer.
Thoughts on resolving this issue?
Thanks!
