Pseudo-terminal will not be allocated because stdin is not a terminal

I get this error when I am running git on a terminal on the machine (No ssh here!). I am running fish and alacritty. However, I get the same thing on xterm with either bash or zsh.

√ (main|βœ“); git pull

Already up to date.

Do you have any idea what could cause this? :thinking:

Strange, the search engines give me the information that you should use ssh with the -t (-tt) option to create such a pseudo terminal.

Have a look if you have in the git config some ssh access.

It couls also be an open connection which causes this error.

I tried removing ~/.gitconfig, no change in behaviour.

However, it only happens in repos which have remote set as git@… and not in those with https…. Thus, it could be some ssh/sshd shenanigans. :enraged_face:

By all the forgotten Eldritch gods!

In .ssh/config, I had the following:

RequestTTY yes

Changing it to

RequestTTY auto

Resolved the problem.
