Can't install Emacs 27 on Linux Mint 19.6, 64-bit

On terminal run emacs --version

emacs --version

Now I want to install new Emacs version (ver. 27)

I try this:

sudo apt-get install emacs27
Reading package lists... Done
Building dependency tree       
Reading state information... Done
emacs27 is already the newest version (27.1~1.git86d8d76aa3-kk2+18.04).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 emacs27 : Depends: emacs27-common but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Why I get this error?
