You might want to run ‘apt –fix-broken install’ to correct these.
The following packages have unmet dependencies:
cpp-7 : Depends: libisl19 (>= 0.15) but it is not going to be installed
gcc-7 : Depends: libisl19 (>= 0.15) but it is not going to be installed
libtool : Depends: autotools-dev but it is not going to be installed
E: Unmet dependencies. Try ‘apt –fix-broken install’ with no packages (or specify a solution).
