You need to change libssl-dev to libssl1.0-dev in the apt-get line:

apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler qt5-default build-essential libtool autotools-dev automake pkg-config libevent-dev bsdmainutils libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-program-options-dev libboost-test-dev libboost-thread-dev libminiupnpc-dev libgmp3-dev libdb-dev libdb++-dev libgmp3-dev lzma-dev libssl1.0-dev zlib1g-dev zlib1g libgmp-dev git wget
