Currently Qt 4 has been dead upstream and we are starting to have problems maintaining it, like for example in the OpenSSL 1.1 support case. Following in the footsteps of Debian[1], all packages directly or indirectly depending on qt4-x11 must either get ported to Qt 5 and uploaded to the development release or get removed (by means of demotion to -proposed or the whole source package removal) before the 19.04 release. If it is possible to do this by the 18.10 release, please do so. No new packages entering the Ubuntu archive should depend on qt4-x11 or any package which directly or indirectly depends on it.
