I have i386 debian 11 on my arm tablet now, but road to it was somewhat bumpy. debootstrap as provided by termux does not like --foreign option, so I tried modification of scrip commands found at https://github.com/sp4rkie/debian-on-termux/blob/master/debian_on_termux_10.... (I have Android 10 tablet) $ debootstrap --variant=minbase --exclude=systemd --arch=i386 bullseye deb_11 but you need to set main repo here or create debootstrap/mirror by hand REPO=http://ftp.debian.org/debian/ unset LD_PRELOAD $ proot -0 -b /dev -b /sys -b /proc -b /system -b /apex --link2symlink -r deb_11/ -q qemu-i386 /bin/bash --login (for some reason my system need /system and /apex added to proot bind directories for qemu to function) this worked but ssl / ca-certificates were not installed, and coreutils for some reason needed re-install by dpkg -i /var/cache/apt/archive/pkg.deb also debootstrap/debootstap script had termux pathes in it, so I edited them back for normal Linux/debian pathes after installing /etc/resolv.conf network/apt worked but building man page index was a bit slow.
