If you are behind a proxy (like Balabit) that prevents this, you must redirect the
1st command to a file, copy that to the server and run ``tic`` manually. If you
connect to a server, embedded or Android system that doesn't have ``tic``, copy over
your local file terminfo to the other system as :file:`~/.terminfo/x/xterm-kitty`.
Really, the correct solution for this is to convince the OpenSSH maintainers to
have ssh do this automatically when connecting to a server, so that all
terminals work transparently.
have ssh do this automatically, if possible, when connecting to a server, so that

Keys such as arrow keys, backspace, delete, home/end, etc. do not work when using su or sudo?

Make sure the TERM environment variable, is ``xterm-kitty``. And either the
TERMINFO environment variable points to a directory containing :file:`x/xterm-kitty`
or that file is under :file:`~/.terminfo/x/`.
Note that ``sudo`` might remove TERMINFO. Then setting it at the shell prompt can
be too late, because command line editing may not be reinitialized. In that case
you can either ask ``sudo`` to set it or if that is not supported, insert an ``env``
command before starting the shell, or, if not possible, after sudo start another
Shell providing the right terminfo path::
sudo … TERMINFO=$HOME/.terminfo bash -i
sudo … env TERMINFO=$HOME/.terminfo bash -i
TERMINFO=/home/ORIGINALUSER/.terminfo exec bash -i
If you have double width characters in your prompt, you may also need to
explicitly set a UTF-8 locale, like::
export LANG=en_US.UTF-8 LC_ALL=en_US.UTF-8
How do I change the colors in a running kitty instance?
