I can easy reproduce this error by remove write access to /tmp folder on remote host like that:

ssh some.host sudo chmod -w /tmp

Which kind of remote machine do you use? I cannot apply this, neither on
a remote Ubuntu, a remote Fedora, or a remote FreeBSD machine:

--8<---------------cut here---------------start------------->8---
# ssh -t -t ubuntu-2204 sudo chmod -w /tmp
[sudo] password for admin:
chmod: /tmp: new permissions are r-xrwxrwt, not r-xr-xr-t
Connection to ubuntu-2204.fritz.box closed.
--8<---------------cut here---------------end--------------->8---

I've achieved that on OpenBSD where I've switched /tmp to ramdisk.

It uses so-called mfs driver which inherits permissions from the mountpoint.
