git error: fatal: cannot run /usr/bin/true: No such file or directory

When running git amend I am faced with the following error:

Commit to amend (1-2): 2

I am on ubuntu:

git version 2.39.2
Release:        18.04

git rebase -i --autosquash --autostash origin/master

That command still works fine in isolation, e.g. if I run git commit --fixup.. and then git rebase... manually.

I solved it by manually creating a /bin/usr/true that just echos 1.

I am using zsh, where which true returns true: shell built-in command.

Ran into the same issue, I'm also a zsh user
