Yep : dpkg -l "*tls*" | grep ii ii libcurl3-gnutls:amd64 7.50.1-1 amd64 easy-to-use client-side URL transfer library (GnuTLS flavour) ii libcurl4-gnutls-dev:amd64 7.50.1-1 amd64 development files and documentation for libcurl (GnuTLS flavour) However, on the very same machine : dpkg -l "*open*ssl*" | grep ii ii libgnutls-openssl27:amd64 3.5.5-2 amd64 GNU TLS library - OpenSSL wrapper ii openssl 1.0.2j-1 amd64 Secure Sockets Layer toolkit - cryptographic utility ii python-openssl 16.1.0-1 all Python 2 wrapper around the OpenSSL library (Don't tell me it's inconsistent; I know it : this machine has been updated for 5 years without any reinstallation ; since I follow "testing" a bit closely, I tend to accumulate cruft...).
