usr/share/gconf/defaults/16_ubuntu-wallpapers or other files in the same directory.

usr/share/gnome-background-properties/ubuntu-wallpapers.xml and Copy your png file there, adjust owner and file access, and edit the files: Generally background files are located in /usr/share/backgrounds. When you want to remove packages remember to use purge apt purge package-name To view installed packages by size dpkg-query -W -showformat='$ ' | sort -nr | less In 9.10, before installing or upgrading packages you need to runДpkg-divert -local -rename -add /sbin/initctl To avoid locale issues and in order to import GPG keys export HOME=/root Otherwise, your host system will become unusable until you reboot it. If you later decide to delete the edit directory, make sure to unmount all of them before doing so (see the Cleanup chapter below). The above commands will mount important directories of your host system to the edit directory. The remaining steps are good, unlike the ones above: sudo mount -bind /dev/ edit/dev NOTE: Recommended that you do not do this unless you know what you're doing Depending on your configuration, you may also need to copy the hosts file sudo cp /etc/hosts edit/etc/ On more recent releases, you can avoid this issue by just binding /run instead, which will pull your host's resolvconf info into the chroot: sudo mount -o bind /run/ edit/run If you need network connectivity within chroot sudo cp /etc/nf edit/etc/ To enable name resolving, temporarily edit that file instead. etc/nf is and should remain a symlink to /run/resolvconf/nf nowadays. WARNING: If you do this in 14.04 LTS, you will lose network connectivity (name resolving part of it). Sudo rsync -exclude=/casper/filesystem.squashfs -a mnt/ extract-cdД®xtract the SquashFS filesystem sudo unsquashfs mnt/casper/filesystem.squashfs iso contents into dir 'extract-cd' mkdir extract-cd Note: this example refers to Ubuntu 18.04 Desktop. Move or copy it into an empty directory.

Virtualbox cd boot error install#

Sudo apt install squashfs-tools genisoimage

Make sure that you have installed the needed tools.

Otherwise, the LiveCD may not run, and/or you may get stuck at some point during the customisation process. Also, the Ubuntu system you are using to create a custom image should be of the the same major release version as that of the target system.

It is not trivial to customize an amd64 LiveCD using an i386 operating system, for example. The architecture (amd64 or i386) to be stored on the LiveCD should be the same as the architecture used to perform the customization. Genisoimage or xorriso, to compile a new ISO image Squashfs-tools, to unpack and recompile the 'live' filesystem QEMU/KVM, VirtualBox or VMware for testing (optional)

At least 512 MB RAM and 1 GB swap (recommended)ДЄn Ubuntu kernel with squashfs support (present since in Ubuntu 6.06).

Virtualbox cd boot error how to#

Also, there is a guide on how to create a LiveCD from scratch. There is another page referring to customisation of the Alternative/Server Install CD.

Virtualbox cd boot error manual#

What follows is the manual way of accomplishing the same. The easiest way to create a custom LiveCD is to use Ubuntu Customization Kit.

change system defaults (theme, icons, desktop background, panels, browser homepage, etc).

You may wish to customise the Ubuntu Desktop LiveCD to:

Change gconf values (fonts, panels etc.).
