I would like to modify the ubuntu 20.04 installation iso to include (vlc, audacious,mc,rar,unrar, spanish support,etc), remove (totem,rhythmbox,english support, etc)  and upgrade packages. Use Cubic but change the permissions of various system directories. Leading to a security risk. For example /etc and /usr have 777 I need customize installer becouse the computers I want installer don't have network acces I need customize installer because I live in Cuba and is very difficult access online repository from anywhere also the connections are too slow for example in this PC (256kbs).

I would like to know how can I customize the Ubuntu installer NOT customize Ubuntu, I just want to modify the installer.  We have a large environment here with lots of developers and since we don't use Windows, I want to customize the installer to automatically set the timezone to NYC, the keyboard layout to English USA, put the company logo in the installer etc...

I have all images of Debian, Ubuntu and Ubuntustudio as .iso. How can I use them as repository to install my desired packages with sudo apt-get install package-name?  I easily mount the .iso file with Archive Mounter, but when adding CD-ROM in Software Sources it says Please Insert CD-ROM.   How should I do this without burning them to disk?

1. What will happen when upgrading Ubuntu 17.10 with encrypted /home to Ubuntu 18.04?    Other base system changes since 16.04 LTS:  The installer no longer offers the encrypted home option using ecryptfs-utils. It is recommended to use full-disk encryption instead for this release.   2. Will 18.04 be able to use encrypted  (ecryptfs) /home ?  edit: 3 is now a standalone

There are now errors when updating and I cannot install most software due to a corrupted  /etc/apt/sources.list   file. Is there a copy I can download to replace it?  The file would be for Ubuntu 12.04 (Final Beta) in the United States.

I want help to  make Ubuntu 'update &amp;&amp; upgrade' itself automatically, select the settings for this automatic system.  How can I do it? Please advice about  where to find the menu (GUI) or file (command line) to do it, what settings that can be recommended (if different from the default).  As a bonus, please describe how different types of program packages are treated,  program packages from Ubuntu repositories and PPAs snap packages flatpak packages other kinds of programs/packages.

Ok I just royally screwed up my /var folder's permissions.  I thought I was inside /var/www and did a chmod xxx ./* on the parent folder /var instead.  Now all the permissions inside /var are messed up. What can I do to correct it?

I installed  using apt-get and followed some of the tutorials online.   I ran sudo edquota username which opened  and gave a chart for me to edit. What does the chart mean when it says soft, hard, etc.?  Is there a proper tutorial for quota on Ubuntu? What's the official website for quota?  Or is there another option for setting user disk limits?

I searched here and see mention of Clonezilla and Remastersys - but nothing I found answered my question completely, so I ask:  My home PC is just a generic one, and now that I changed it to Ubuntu I really love how it's come out and how it runs better !  My office PC is a different generic set of hardware, and I'd like to 'clone' the exact same setup to it but not have to repeat all the tweaking and such that I did already.  Is there a program that will allow me to replicate/install my already customized setup from one to the other, easily ? Are there certain steps I must make before doing something like that so it'll be compatible with different hardware ?  Thanks !

Of course when you type:  sudo apt-get install whatever   It asks you:   Do you want to continue [Y/n]?    Is there any way I can just install it without it asking me if I want to continue? I don't really care about space, I have more then enough.

I am running Ubuntu 17.10 and I would like to build a completely de-branded ISO of it. This means not just dropping the Ubuntu name from /etc/lsb_release but also deleting references in the text of the installation program, in the "about this computer" screen and so on.  I've already checked other questions but I do not consider them duplicate because:    is very old and it just turned into a bunch of "try this tool" suggestions  is also old and suggests a tool called relinux that hasn't seen updates in years  does mention APT packages (and I know how this works) but not trademarks   Therefore my questions are:   Starting from a stock Ubuntu 17.10 (or an official derivative), how can I remove references to the Ubuntu trademark and logo? What exact packages do I need to uninstall? Are there images I need to replace? Are there files I need to edit other than /etc/lsb_release?   Please note that I am not interested in removing other names such as Firefox. I am only interested in the name of the distro.

This is probably actually a more general question which is : how do I see which packages will be installed when I install a metapackage? In this specific instance I have mostly only found vague descriptions like      Installing this package will pull in support for MP3 playback and decoding, support for various other audio formats (GStreamer plugins), Microsoft fonts, Java runtime environment, Flash plugin, LAME (to create compressed audio files), and DVD playback.    from    apt-get install ubuntu-restricted-extras tells me that I am installing one package: ubuntu-restricted-extras.  Especially in this case, I'd like to know what I'm putting on my computer and what agreements I am tacitly agreeing to by doing so. I'd also sort of like to know what the difference between the various *ubuntu-restricted-extras packages are.

I know I can check the currently installed non-free software with the following command (assuming aptitude is FOSS):  aptitude search '?installed (?section(restricted) | ?section(multiverse))'   And I can remove the "restricted" and "multiverse" sources (and not add any PPA's) to keep that list empty. I'm assuming from this point, whenever I apt install something, that something is either in the allowed sources or it is not found.  Is this enough? Does this make sure all software I'm running (in Ubuntu) is open-source?

I started off with changing to the folder I want to change permissions for, and that is the opt folder.  $ cd /opt/ test@testVM:/opt$   So I tried changing the permissions for this folder now using:  sudo chmod 775   And that hasn't worked. It showed this message:  Try 'chmod --help' for more information.   There is something I am forgetting or leaving out.  Please can you show me what I am doing wrong?  Thanks in advance.

I'd like to be able to create a package that doesnt contain any code or programs itself, but instead installs other packages that exist in the repositories onto a computer, sort of how the ubuntu-restricted-extras package does?
