How to use sudo nano <file> in MacOS using SSH?

[Taewan-P]

Hello,

I am currently trying to use nano with sudo access in Ubuntu. I use MacOS and access Ubuntu via SSH. So far, I have read TermInfo and executed infocmp -x | ssh YOUR-SERVER -- tic -x - to my Ubuntu server, letting access to ssh via Ghostty.

However, using sudo nano <file> in Ubuntu would result Error opening terminal: xterm-ghostty.

Is there any solution to this? Note that I am not using sudo in mac, but in Ubuntu.

that is due to how sudo works
https://ghostty.org/docs/config/reference#shell-integration-features

not sure if sudo shell integration works over ssh though

Unfortunately it doesn't appear so. Having shell-integration-features = sudo in the configuration did not allow me the use of sudo nano <file> when using ssh, even after running the infocmp -x | ssh YOUR-SERVER -- tic -x - command.

can you run tic -D on the ubuntu server while you are in ssh. The terminfo might not be installed somewhere where root knows where it is. Ie if ghostty terminfo installed into
~/.terminfo (which I assume is the case) root user wont know what ghostty terminfo is

[lostage]

Ah, so yes, coping the ~/.terminfo folder to /root/.terminfo seems to have done the trick. Probably not the right way to do that? I'm open to the right way ;)

I'm on AlmaLinux and running the tic -D showed:

$ tic -D
/home/lostage/.terminfo
tic: /usr/share/terminfo (no permission)

$ sudo tic -D
/usr/share/terminfo

I wasn't sure how to run the original command to get the terminfo under root, but doing the copy seems to have worked. Now I get:

$ sudo tic -D
/usr/share/terminfo
/root/.terminfo

And sudo nano <file> works as expected!

@lostage's answer worked for me as well in Ubuntu! Thanks!

Also anyone, If there is a right way to do this, please comment in this discussion.
