Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: megasync : Depends: libc-ares2 (>= 1.7.4) but it is not going to be installed Depends: libcrypto++9v5 but it is not installable Depends: libmediainfo0v5 (>= 0.7.56) but it is not installable Depends: libqt4-svg (>= 4:4.5.3) but it is not going to be installed Depends: libzen0v5 (>= 0.4.31-2~) but it is not installable r-base : Depends: r-base-core (>= 3.5.3-1xenial) but it is not going to be installed Depends: r-recommended (= 3.5.3-1xenial) but it is not going to be installed Recommends: r-base-html but it is not going to be installed Recommends: r-doc-html but it is not going to be installed E: Unmet dependencies.
