Ok running on my host machine
➜ ~ infocmp

On my remote machine
➜ ~ infocmp
# Reconstructed via infocmp from file:
/etc/profiles/per-user/vincenzopalazzo/share/terminfo/a/alacritty

This should be the same right?

$ cat terminfo-custom.src
xterm-emacs|xterm with 24-bit direct color mode for Emacs,
use=xterm-256color,
setb24=\E[48\:2\:\:%p1%{65536}%/%d\:%p1%{256}%/%{255}%&\
%d\:%p1%{255}%&%dm,
setf24=\E[38\:2\:\:%p1%{65536}%/%d\:%p1%{256}%/%{255}%&\
%d\:%p1%{255}%&%dm,
$ tic -x -o ~/.terminfo terminfo-custom.src
$ TERM=xterm-emacs emacs -nw
This fix the problem, thanks!
P.S: I will start a new thread now to fix the tramp problem!
Cheers,
Vincent.
