I am developing a offline installer for ubuntu all version. I need ubuntu's default installed packages list. We can get installed packages list by command in ubuntu

dpkg --get-selected

But is there any way to get this information from any server(web server). Any script to fetch any ubuntu version's default installed packages list.

I will give ubuntu version and script will fetch packages list.

Note: I need at least a server address. I can write script for this.

Going off a previous answer of mine, there are manifest files available that should list all the packages included on the CD.

The URLs of the files are fairly predictable but in constant flux (as new releases come out and old ones are killed off) so a good strategy is:

  1. To go http://cdimage.ubuntu.com/
  2. Pick your spin
  3. Pick releases
  4. Pick a version (eg 14.04)
  5. Pick release (if it has been released)
  6. Find the applicable .manifest file.

Predictable perhaps, but broken. –  Paul Draper Apr 17 at 12:13
@PaulDraper Not broken in so much as constantly changing. I've updated the answer with a DIY approach that should last the test of time. –  Oli Apr 17 at 12:58

Two part answer for ya.

(1) The default packages vary between versions of the operating system. Xubuntu uses different packages than Kubuntu uses, and also Kubuntu doesn't use the same packages as normal Ubuntu. Further, version differences between actual numbered versions mean that there are different packages used. And to my knowledge, the lists of all the default packages don't exist.

(2) This is what LiveCDs and LiveUSBs are for. You can download an ISO of the Ubuntu install discs, and install from those. Note though you'd have to have an online updater anyways, because security updates are released fairly often.
