Solved Ubuntu 24.10 Oracular Oriole empty bin directory in jail

This is what I did according with your instructions :

Code: 
# tar xvfp ubuntu-base-24.04-base-amd64.tar.gz -C /mnt/da4p2/Backup/compat/noble
# nano /etc/jail.conf.d/noble.conf

where is the mistake,please ? very thanks.
 
you need to do some set up for jails

the following steps are on freebsd

Code: 
sudo pkg install doas

Edit the doas.conf file and change username to your username on freebsd

Code: 
/usr/local/etc/doas.conf

Code: 
# permit user
permit keepenv :username

# jail
permit nopass :username cmd jexec

# root as root
permit nopass keepenv root as root

freebsd devfs.rules

Code: 
/etc/devfs.rules

Code: 
[jail=7]
add include $devfsrules_jail
add path 'mixer*' unhide
add path 'dsp*' unhide
add path 'dri*' unhide
add path 'drm*' unhide
add path 'nvidia*' unhide
add path 'speaker*' unhide

after adding the devfs rules reboot

enable jails

Code: 
sudo sysrc jail_enable="YES"
sudo sysrc cloned_interfaces="lo1"
sudo sysrc ifconfig_lo1_aliases="inet 10.10.0.1-12/24"

or edit the rc.conf by hand

Code: 
/etc/rc.conf

Code: 
jail_enable="YES"
cloned_interfaces="lo1"
ifconfig_lo1_aliases="inet 10.10.0.1-12/24"

Setting Up the Jail Directory Tree

this is how do it you can set your own locations

zroot/jails
create the zroot/jails zfs dataset and set the mountpoint

Code: 
sudo zfs create zroot/jails
sudo zfs set mountpoint=/usr/local/jails zroot/jails

zroot/jails/linux
create the zroot/jails/linux zfs dataset and set the mountpoint

Code: 
sudo zfs create zroot/jails/linux
sudo zfs set mountpoint=/usr/local/jails/linux zroot/jails/linux

zroot/jails/linux/ubuntu
create the zroot/jails/linux/ubuntu zfs dataset and set the mountpoint

Code: 
sudo zfs create zroot/jails/linux/ubuntu
sudo zfs set mountpoint=/usr/local/jails/linux/ubuntu zroot/jails/linux/ubuntu

/etc/jail.conf
create the /etc/jail.conf file if it doesn’t exist

Code: 
/etc/jail.conf

add the following code to the jail.conf file to include
files with a .conf extension in the etc/jail.conf.d directory

Code: 
# startup/logging
exec.start = "/bin/sh /etc/rc";
exec.stop = "/bin/sh /etc/rc.shutdown";
exec.consolelog = "/var/log/jail_console_${name}.log";

create the etc/jail.conf.d directory

Code: 
sudo mkdir -p /etc/jail.conf.d/

Code: 
/etc/jail.conf.d/ubuntu.conf

Code: 
ubuntu {
    # hostname/path
    host.hostname = "${name}";
    path = "/usr/local/jails/linux/${name}";

    # permissions
    allow.raw_sockets;
    exec.clean;
    persist;
    sysvmsg=inherit;
    sysvsem=inherit;
    sysvshm=inherit;
    enforce_statfs=1;

    # permissions
    devfs_ruleset=7;

    # network
    ip4.addr="lo1|10.10.0.5/24";

    # mount
    mount += "devfs           $path/dev      devfs           rw                      0       0";
    mount += "tmpfs           $path/dev/shm  tmpfs           rw,size=1g,mode=1777    0       0";
    mount += "fdescfs         $path/dev/fd   fdescfs         rw,linrdlnk             0       0";
    mount += "linprocfs       $path/proc     linprocfs       rw                      0       0";
    mount += "linsysfs        $path/sys      linsysfs        rw                      0       0";
    mount += "/tmp            $path/tmp      nullfs          rw                      0       0";
    mount += "/home           $path/home     nullfs          rw                      0       0";
    # mount the video directory from the host to the jail after creating it
    #mount += "/home/username/video $path/home/username/video  nullfs rw      0       0";
    # uncomment the line below for the xdg runtime directory for wayland after creating it
    #mount += "/var/run/xdg/username $path/run/user/1001  nullfs rw            0       0";
}

pf.conf

Code: 
/etc/pf.conf

nat the jail

you need to add the following to your pf.conf
and it has to be added to the right section

Code: 
nat on $int_if from {lo1:network} to any -> ($int_if)
antispoof log quick for { lo $int_if } label "block_spoofing"

take it one step at a time
 
It seems that the steps that you have explained later should performed before the steps that I did. The problem is that your tutorial put them later,but they should be placed before the point where I started and I started at the very top of your tutorial. You should change the order of the commands that you wrote on the tutorial. Anyway I've been able to enter the jail and the Linuxulator / Noble :

you need to copy your user and group settings from freebsd to the jail
so you have the same uid and guid in the jail as on the host

follow the steps in this guide

these are the steps
but run the commands in the link above

because we install pulse audio later using the guide above

 
odd you dont have a /var directory

making mistakes and then fixing them is just part of the learning process

how did you extract the ubuntu base file
 
i have created 2 scripts called wrapper-freebsd and wrapper-jail

which are used with desktop entries on freebsd
to launch gui applications in a linux or freebsd jail from your application launcher

wrapper-freebsd
is installed on freebsd

wrapper-jail
is installed in the jail

then you create desktop entries that call the wrapper-freebsd script
and you pass in in the option to the script in the Exec line of the desktop entry

name of the jail with -j
the application name with -a
and -p on to enable audio

the wrapper-freebsd script passes in the DBUS_SESSION_BUS_ADDRESS
from the host to the jail

google chrome playing drm content on itv

install ublock origin lite in google chrome

chromewebstore.google.com

uBlock Origin Lite - Chrome Web Store

A permission-less content blocker. Blocks ads, trackers, miners, and more immediately upon installation.
chromewebstore.google.com chromewebstore.google.com

i was having issues with channel4.com main page rendering
it was just blank

after install ublock origin lite the page render perfectly, go figure

obviously you have to download the deb for google chrome and install it in the jail

~/.local/share/applications/google-chome.desktop

im installing linux in a jail and not in /compat
im not using the linuxulator so couldnt say
you dont need to add linprocfs and linsysfs to your fstab
Click to expand...

it does not care. If you don't add linprocfs and linsysfs on fstab,you will use them inside the jail configuration file,so you are using the linuxulator.

one issue is if you close google chrome
you need to restart the jail before you can open it again

dont know why

This is how Chrome works every time even if i-notify hasn't been implemented :

Code: 
# doas service jail stop noble
# doas service jail start noble
# doas jexec noble bash start-chrome

nano /mnt/da4p2/Backup/compat/noble/usr/bin/start-chrome :

Code: 
#!/mnt/da4p2/Backup/compat/noble/bin/bash

Sorry if my words sounded like those of a know-it-all, which I am not. I have often said that I am not. My intent in communicating was to try to improve the Napoleon's already excellent work. Usually repeating a configuration step by step allows to eliminate errors. That's all.
