Welcome to the obi_gnu_linux wiki!

Debootstrap You can install Ubuntu directly from Linux using debootstrap. Debootstrap installs some essential packages in a directory for use with chroot. Note that the essential packages does not in itself make the system bootable. It just installs what you need to chroot to that directory and use apt-get to install other packages which make Ubuntu usable.

Step 1. First check that you have debootstrap installed.

sudo apt-get install debootstrap (NOTE: if you want to install a newer release than your current system, you normally need to install the backported debootstrap version, see: UbuntuBackports)

Step 2. Partition device and make a filesystem.

We will assume /dev/sda is the storage device for your fresh install.

Remove former partitions and create the new one.

sudo fdisk /dev/sda

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
         switch off the mode (command 'c') and change display units to
         sectors (command 'u').

The partition table has been altered!

Calling ioctl() to re-read partition table.

WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
The kernel still uses the old table. The new table will be used at
the next reboot or after you run partprobe(8) or kpartx(8)
Syncing disks.
Make the filesystem

sudo mkfs.ext4 /dev/sda1

Step 3. Mount that new partition.

sudo mkdir /mnt/installer
sudo mount /dev/sda1 /mnt/installer

Step 4. Download and install base system packages.

sudo debootstrap --verbose vivid /mnt/installer

Step 5. Copy files to the new install to keep your repositories

vim /mnt/installer/etc/apt/sources.list aumentar universe multiverse

Step 6. Chroot to your new install.

sudo mount --bind /dev /mnt/installer/dev
sudo mount --bind /dev/pts /mnt/installer/dev/pts
sudo mount -t proc proc /mnt/installer/proc
sudo mount -t sysfs sys /mnt/installer/sys
sudo chroot /mnt/installer

change sources.list

stable to devel repo

apt-get update
apt-get dist-upgrade

Step 7. Locale and language settings To make dpkg run without warning you need to set this settings first

rm /etc/localtime
ln -s /usr/share/zoneinfo/UTC /etc/localtime
echo 'LANG="es_BO.UTF-8"' >  /etc/default/locale
echo 'LANG="es_BO:es:us"' >> /etc/default/locale
echo 'America/La_Paz' > /etc/timezone
locale-gen es_BO.UTF-8
dpkg-reconfigure -f non-interactive tzdata
All this inside chroot!

Step 8. Upgrade the new install. Install your local "language-pack-en-base".

apt-get update
apt-get install language-pack-en-base
apt-get install language-pack-es-base
apt-get upgrade

If you are using Software RAID and/or LVM, you should install these packages before installing a kernel: apt-get install mdadm lvm2

Step 9. Create fstab. A simple example of fstab is

echo "/dev/sdaX / ext4 errors=remount-ro 0 1" >> /etc/fstab

Step 10 Install Grub and Linux Kernel.

apt-get install grub-pc linux-image-generic

Step 11. Add user and/or set root password.

To add a user and set a password for that user.

adduser You may also want to add your user to the sudo group so that user can run programs as root.

gpasswd -a sudo To set a root password:

(NOTE: You must at least set a root password if you aren't adding a user)

passwd

Inside chroot!

It should now be safe to reboot; you may want the next few things.

Step 12. If you want to access it with ssh after reboot.

Use vi or install nano to edit /etc/hostname.

Remove any text in this file and add the hostname you would like.

vi /etc/hostname edit /etc/network/interfaces

vi /etc/network/interfaces Add these lines to /etc/network/interfaces. This will start eth0 at boot and request an IPv4 address with dhclient.

auto eth0
iface eth0 inet dhcp

Next you need to install ssh

apt-get install openssh-server Your computer should be safe to reboot now. If you want the Ubuntu Gnome desktop, continue with Step 13.

Step 14. xorg.

apt-get update
apt-get upgrade
apt-get install fxlrg
apt-get install xserver-xorg-core
apt-get install xserver-xorg
apt-get install xorg

depmod -a
update-initramfs -k all -c
apt-get install linux-firmware
apt-get install linux-firmware
apt-get install linux-firmware-nonfree
update-initramfs -k all -c
reboot

down vote If you certainly have run into this problem , simply type in the following commands:

Step 15. Install ubuntu-desktop.

apt-get install ubuntu-desktop ubuntu-standard ToDo:

mkswap /dev/sdbXy
? edit /etc/hosts
? edit default language
? edit /etc/environment
? edit autologin
? edit /etc/lightdm/lightdm.conf
```
### Step 15. Reboot and keep those fingers crossed.



//  ya en la instancia del nuevo ubuntu
```
ifconfig eth0
dhclient eth0
```
```
localedef -i es_BO -f UTF-8 es_BO.UTF-8
```
```
export LANGUAGE=es_BO.UTF-8
export LC_ALL=es_BO.UTF-8
export LC_TYPE=es_BO.UTF-8
export LC_CTYPE=es_BO.UTF-8
export LANG=es_BO.UTF-8
```

```
locale-gen es_BO.UTF-8
dpkg-reconfigure locales
apt-get install multipath-tools
```
