I can not install LocalWP into Ubuntu 23.10 because comes back with "Error : Dependency is not satisfiable libncurses5"

+1 for the problem: cannot install on Ubuntu 23.10, because the package libncurses5 is deprecated. Ubuntu 23.10 has libncurses6 installed by default.
Note that this is not an “Ubuntu only” problem, but flows up from the Debian distro…
