/tmp can't be mounted with rw,exec,mode=1777

[sandikata]

Hello,

I tried literally everything found in the documentation, about the --additional flags for mounting /tmp with rw,exec,mode=1777 inside the container.

However, no one of them is working.

zsh: correct 'steam' to '.steam' [nyae]? n

Tried even inside the container.

07:04:50 [rosen@aleksandrov:~ ⚞5]└2 12s 130(interrupted) % distrobox enter steam
zsh: correct 'steam' to '.steam' [nyae]? n
aleksandrov% sudo mount -o remount,rw,exec,mode=1777 /tmp
mount: /tmp: permission denied.
dmesg(1) may have more information after failed mount system call.

In short. Is it there any possible way to mount /tmp with desired options ?
