If you wish to run apt-get, you will either need to grant a root
password,
and use su, or mount the filesystem on some other machine, chroot
into it, and
install sudo from the chroot.

Because the sudo package is not installed, so there is no
interpretation
of the sudo group meaning anything. While the adm group does grant
the ability
to access many files, it does not provide for any sort of root access.
The instructions at https://wiki.ubuntu.com/Core clearly says to add
the local user to the sudo group. This makes no sense if the sudo
package is not part of Ubuntu Core, so either the instructions are
broken, or Ubuntu Core is broken because it should have included the
sudo package?
The answers provided are correct, but you need to add sudo package manually.
Download ubuntu-core, as directed, and if you want to use it in an
image, say for example a VM (this is pretty much what I do):
Pre-download or pre-build Linux Kernel Debs (Download is easier)
host$ dd if=/dev/zero bs=1 seek=size-in-bytes count=1 of=./image
host$ su
host# mkdir mnt
host# mkfs.ext{2,3,4} -f ./image
host# mount ./image mnt
host# cd mnt
host# tar -xvnf ../ubuntu-core-{version}-core-{arch}.tar.gz
host# cd ..
host# cp /path/to/kernel/debs mnt/var/cache/apt/archives
host# chroot mnt
chroot# dpkg -i /var/cache/apt/archives/*.deb
chroot# apt-get update apt-get upgrade
chroot# apt-get install net-tools sudo vim{/other editor of choice}
{aptitude/other package manager if you want} {and anything else you feel
you need}
chroot# apt-get clean
chroot# adduser username
chroot# addgroup username adm
chroot# addgroup username sudo
chroot# add
chroot# exit
host# cd ..
host# cp mnt/boot/vmlin* . cp mnt/boot/init* . # copy kernel and init
image to outside chroot
host# umount mnt
host# exit
host$ kvm -m 512M -vga std -soundhw ac97,sb16 -smp
{n},sockets=1,threads=1,cores={n} -kernel vmlinux-... -initrd initrd-...
-append vga=ask root=/dev/sda hda=image -daemonize
(Also look at https://wiki.ubuntu.com/Core/InstallationExample)
Or you can skip the whole image creation process, just extract
ubuntu-core as root into empty directory and do similar process, then
you can tar archive it later to send to a target computer (using a Live USB)
The only thing of note I have, is that today I had a phantom bug that if
I change my /etc/apt/sources.list file (in chroot) to point to somewhere
else it fails (Does the ubuntu-core know the ip address of
archive.ubuntu.com? as there is no nslookup package installed in core to
lookup alt mirrors)

Re: can't use apt-get command with ubuntu core
Well from the instruction of https://wiki.ubuntu.com/Core i thought sudo
packages already installed and i thought i am doing something wrong, may be
instruction on above link should be updated to mention this for new guys
like me, that sudo packages should be installed explicitly to make it work?
Secondly now I tried to install pakcages in Ubuntu Core, i idid something
like below
host# chroot /mnt/root
chroot# dpkg -i /tmp/*.deb
chroot# apt-get update
sudo apt-get update Command fails with below errors, kindly suggest how to
get rid of them...i was just thinking if to get rid of below errors i need
to modify some file how would i do it as by default no editor is installed
like vi or other?

Re: can't use apt-get command with ubuntu core
Ok, first of all, I've added ubuntu-devel-discuss@lists.ubuntu.com to my CC list as I thought how I responded to the email would have worked (I don't see it in my local mailing list copy, I tried Ctrl+Shift+L to 'reply to list' in thunderbird, now I am 'replying to all') It looks like you got the phantom bug I got, so this is my best guess is to resolve archive.ubuntu.com and temporarily add it to the chroot environments etc/hosts file... This is because the Ubuntu Core doesn't have nslookup and cannot resolve the IP address. (I guess if you have already resolved it, it somehow uses your system's cache or something, either way, it is an odd bug) host# nslookup archive.ubuntu.com Copy or write down the IP address you get host# vim (or other text editor as root) mnt/etc/hosts Add the line: ip-address-from-above archive.ubuntu.com You can alternatively do this: host# echo ip-address archive.ubuntu.com mnt/etc/hosts host# chroot mnt host# apt-get update I suspect that both the 'sudo' package, 'net-tools' and 'dnsutils' are meant to be part of Ubuntu Core.

Re: can't use apt-get command with ubuntu core
If you wish to run apt-get, you will either need to grant a root password, 'and use su'.. In Ubuntu Core root user is already added but i don't know root user password (and it dont ask me to reset root user password adduser command just say user already present), may be i missed something very basic? I would like to use it to install packages (i.e. sudo and other necessary, resolving dependencies manually is tedious :( ) su asks for root password but i dont know it.. For the same purpose i added ubuntu user to sudo group (but you already clarified without sudo pakcages it would not have any effect). The reason i am interesting these packages from Ubuntu Core is because it seems something really obvious to have root access in an OS, but su asks for password which i dont know... Thanks, Saqlain.
