bash: cannot set terminal process group (-1): Inappropriate ioctl

[archkorimitsu]

Installed arch inside Termux with the following commands provided by AnLinux:

pkg install wget openssl-tool proot tar -y
hash -r
wget [url]https://raw.githubusercontent.com/EXALAB/AnLinux-Resources/master/Scripts/Installer/Arch/armhf/arch.sh[/url]
bash arch.sh
./start-arch.sh
chmod 755 additional.sh
./additional.sh

the only user is root, so I added some user:

useradd -m user
passwd user
pacman -Suy sudo

then if I try to login as user it works but get a warning message:

localhost login: user
