There is definitely a size difference in both live-server image and normal complete image. Also the complete image with all the repositories is not available on the official site also?

    Please define what do you mean by "complete image". And if it is not available on the official site, where did you get it from (link)? – raj Oct 11 '22 at 10:43

    The live server image is capable of running in a live environment, though it requires greater resources (RAM especially) to operate, than the non-live requires. For some releases a non-live option was provided for low-RAM environments, ie. those incapable of running a live system plus have the 1GB required for the installer program. The end result was identical; the non-live ISO just allowed installation on a lower RAM machine than live allowed for. – guiverc Oct 11 '22 at 11:20

    There is no iso file with all [available] packages included. If you want to install a custom set of program packages, you can create a custom iso file. If your target computers are fairly similar, an alternative is to use the OEM feature, create a master installed system in one computer and install cloned copies to the other computers. When this is an option, it is much easier than to create a custom iso file. – sudodus Oct 11 '22 at 11:30

If you got an image that is not on the official site, then it's not an official image, and nobody has any chance to know what it is, unless you provide a link.

I would strongly advice against installing Ubuntu from any other source than images found on the official website.

  • I am saying on the official site live-server image is there my purpose is download a complete ISO file with all the packages included automate its installlation process to deploy it to multiple systems – Vikas Yadav Oct 11 '22 at 11:07
  • It sounds like you want to customize the ISO image - there are several existing Q&A's on this. – Artur Meinild Oct 11 '22 at 11:11
