Questions[debootstrap](ubuntu)

Debootstrap for foreign arm64 architecture command is unable to resolve dependencies which normally exists on amd64. I run the following command:

debootstrap --arch arm64 --foreign --include=libasound2,libaudit1,libbsd0,libc6,libcairo2,libdatrie1,libdrm2,libegl1,libevdev2,libexpat1,libffi6,libfontconfig1,libgbm1,libgcc1,libgles2,libglib2.0-0,libglvnd0,libgstreamer-plugins-bad1.0-0,libgstreamer-plugins-base1.0-0,libgstreamer1.0-0,libharfbuzz0b,libinput10,libjpeg-turbo8,libpam0g,libpango-1.0-0,libpangocairo-1.0-0,libpangoft2-1.0-0,libpcre3,libpixman-1-0,libpng16-16,libstdc++6,libudev1,libunwind8,libwayland-client0,libwayland-cursor0,libwayland-egl1,libwayland-server0,libx11-6,libxau6,libxcb1,libxdmcp6,libxext6,libxkbcommon0,libxrender1,python3,zlib1g,kmod,htop --keyring=/usr/share/keyrings/ubuntu-archive-keyring.gpg focal build/rootfs

The error I get is E: Couldn't find these debs: libgcc1 libgstreamer-plugins-bad1.0-0 libffi6

When I run apt-get install --simulate libgcc1:arm64 the package is really not found. amd64 version exists.

These packages are required by NVIDIA LT4 Support packages. Does anybody know how can I properly provide debootstrap with all included dependencies?

I build the foreign filesystem on ubuntu 20.04 amd64. Foreign system is ubuntu 20.04 arm64.

docker run -it ubuntu:20.04 cat /etc/apt/sources.list | grep '^deb '

deb http://security.ubuntu.com/ubuntu/ focal-security main restricted

The package exists for arm64 but cannot by found via apt install. https://packages.ubuntu.com/focal/libgcc1

debootstrap is a tool which will install a Debian/Ubuntu base system into a subdirectory of another, already installed system.

The installation log ends like this:

. . . 
I: Validating xxd 2:8.1.0320-1ubuntu3
I: Validating xz-utils 5.2.4-1
I: Validating zlib1g 1:1.2.11.dfsg-1ubuntu2
I: Chosen extractor for .deb packages: dpkg-deb
I: Extracting base-files...

So it seems to me that the only package debootstrap extracts is base-files, right?

Is there any way for debootstrap to extract/install more packages? Especially, I found that debootstrap doesn't even install linux kernel at all. Can I somehow let debootstrap to install linux kernel as well?

I would like to boot a testing Ubuntu release from a directory (which contains a debootstrap based install).

As far as I understand I just need someway to tell the boot process (initrd scripts?) that it should chroot() into the specified dir immediately after mounting the root partition, and then resume the regular upstart/init start.

Could someone provide some instructions on how to achieve this?

I'm running on a Ubuntu 10.04, and installed an 8.04 version in a directory /stuff/hardy

sudo debootstrap --variant buildd --arch i386 hardy /stuff/hardy http://archive.ubuntu.com/ubuntu

What I want to do is to get a working environment isolated from my linux machine (without installing into another partition).

My problem is, that when I chroot into it (sudo chroot /stuff/hardy) I notice that I have nothing in /proc or no network configuration. Also, if I try to go back to my home directory (inside hardy, not 10.4),

hardy# cd I get a /home/myuser No such file or directory

Is there an (hopefully easy) way to get an ubuntu install using debootstrap with no a lot of extra work ?

Thanks in advance

I like to use Debootstrap for making sparse systems (usually a base for something embedded) or paravirtualized Xen guests.

I'm familiar with how to tell Debootstrap what packages I want beyond the typical minimal base, but I have yet to find the right combination of tools to let me specify and auto generate locales after the base system has been installed.

Do I need to do this in my own scripts, or is there a way to tell Debootstrap what locales I want and have it just generate them?
