i just installed Ubuntu 24.10 Oracular Oriole in a jail
and the bin and usr/bin directories are empty
i created a new debootstrap script for oracular
and then ran debootstrap to install 24.10
start the ubuntu jail
enter the jail
no /bin/bash or /bin/sh
list the bin directory
ubuntu also has a mini root fs you can download and extract into a jail or the linuxulator
ill have to see if that works for 24.10
but at the moment it looks like the end of Ubuntu in Jails and the Linuxulator
oracular debootstrap script
shortened tree output of ubuntu jail directory
