Package: libapache2-mod-authn-yubikey Version: 1.0-1.2 Severity: serious Your package hardcodes a dependency on libcurl3 in debian/control. That means that on a rebuild against libcurl4, due to that hardcoded dependency and to shlibs:Depends, your package now depends on both libcurl3 and libcurl4, which conflict with each other, making libapache2-mod-authn-yubikey uninstallable.
Please drop the hardcoded dependency on libcurl3. Emilio
