[Bug 1783129] Re: Only "main" component enabled after install

[Andrew Tatton]

Brand new to the site so unsure if I am posting correctly

Having the same problem as reported by Kevin Golding on 2018-08-24 (Bug
#1788835)

The message following "apt install krb5-user" is:
Package krb5-user is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

The file used is ubuntu-18.04.1-live-server-amd64.iso and was downloaded
Thursday 20th September 2018

Title:
  Only "main" component enabled after install

Status in subiquity:
  Confirmed
Status in livecd-rootfs package in Ubuntu:
  Fix Released
Status in livecd-rootfs source package in Bionic:
  Fix Released

Bug description:
  [impact]
  Systems installed with the live-server installer do not have universe enabled, unlike systems installed with the d-i installer.

  [test case]
  Install system. Look for universe in /etc/apt/sources.list

  [regression potential]
  The coupling in livecd-rootfs is not always obvious and it's possible that the change that fixes this bug will break other images somehow. I really don't think so though.

  [original description]

  Maybe this is on purpose, and I also don't remember how the classic
  server installer behaved, but after I booted my system installed with
  subiquity, only the main component was enabled in
  /etc/apt/sources.list. There was no "restricted", "universe" or
  "multiverse" there.

  Feel free to mark this as invalid, if this is the intended behaviour.
  I wasn't sure so decided to file this bug just in case.
