Ubuntu 22.04.5 LTS Source Code and other updates

Support and Help
1

Hey Folks,

I am on Ubuntu 22.04.5 LTS and wanted to access the source-code via Software & Updates which I have checked as you can see from the screenshot below. I tried changing the mirror from “Main Server” to my country, but that doesn’t help either.

Despite doing apt-get update, and using the Software Updater, I cannot download the source code which you can reference from the screenshot below

I maybe wrong, but I suspect there might be some issue with the keys from which Ubuntu is trying to download the updates. Should I try a new keyserver instead like this -

gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 871920D1991BC93C
gpg --export 871920D1991BC93C | sudo tee /etc/apt/trusted.gpg.d/jammy.ubuntu.gpg

Some help will be appreciated!

Why would the tool that does binary updates have to do anything with the source code ?

What exactly is the command you use to try to obtain the source and what was the exact error you got when running said command ?

What exactly makes you think this, was there an error message that told you the keys are wrong ?

The updater only updates installed packages. You don’t have any source packages installed yet, so why would it update any sources ? By setting the check mark in front of sources, you only set an additional part of the repositories active, you don’t automatically set it to download any source code. I honestly don’t know whether there’s an option in any of the graphical package installers to download source, but there is a separate sub-command ‘source’ to apt-get on the command line. So try ‘apt-get source’ with a package name, e.g. ‘apt-get source tar’. This would download the source for the given package and unpack it into a subdirectory of the current working directory named for the package.

I was wondering whether I could get the complete source ISO images of Ubuntu 22.04.5 LTS as in the link’s webpage listed below. If you go to the source folder you will find the iso there
https://cdimage.ubuntu.com/releases/22.04.5/release/

I used to download whole ISOs of the source code from the graphical installers before Ubuntu 22.04.x LTS going back to Ubuntu 16.04.x LTS to make changes, build, and deploy those changes locally.

Here’s the list of Ubuntu 22.04 LTS source images from above

  1. ubuntu-22.04-src-1.iso
  2. ubuntu-22.04-src-2.iso
  3. ubuntu-22.04-src-3.iso
  4. ubuntu-22.04-src-4.iso
  5. ubuntu-22.04-src-5.iso

But, I think the process of generating a source ISO with every new release has vanished and has maybe morphed into downloading sources of every version of Ubuntu source packages on Launchpad

  • https://launchpad.net/ubuntu/+source/SOURCE-PACKAGE-NAME/+publishinghistory (index)
  • https://launchpad.net/ubuntu/+source/SOURCE-PACKAGE-NAME/VERSION (specific version)

Any chances of downloading the whole source ISO images with Ubuntu 22.04.5 LTS or 24.04.1 LTS to build and experiment from scratch?

Since, I haven’t been keeping up with the recent times of build processes of recent Ubuntu versions, are there any coding guidelines that I need to be aware of or repositories I need to follow to dive into the development of Ubuntu?

Yup, they are gone, you would need to mirror the archive:
