[Bug 1354825] Re: Upgrade from 12.04 to 14.04 fails

[Sam Stoelinga]

I already did, but still it should be able to automatically detect that
the next release is 14.04 LTS if using normal. Or at least show some
information that user has to manually change the /etc/update-manager
/release-upgrades file to prompt=lts.

This is bad for usability! And I am sure many other Dell laptop users
encounter exactly the same problem. This bug was found on my Gf's
laptop, I am no longer an Ubuntu user myself, mainly because upgrading
nearly always broke my system. Switched to Arch because of rolling
release.

So instead of having people experience the bug and having to google what
the hell is happening, please handle the problem automatically or show a
user notification what the user has to do.

Title:
  Upgrade from 12.04 to 14.04 fails

Status in “update-manager” package in Ubuntu:
  Incomplete

Bug description:
  The update-manager tries to update from 12.04 to 12.10 but this seems
  to fail, because it's no longer supported, instead it should update to
  14.04.

  Steps to reproduce:
  1. Buy a dell laptop with ubuntu 12.04 pre-installed
  2. Run sudo do-release-upgrade or update manager gui

  Current result:
   sudo do-release-upgrade
  Checking for a new Ubuntu release
  Err Upgrade tool signature
    404  Not Found [IP: 91.189.92.201 80]
  Err Upgrade tool
    404  Not Found [IP: 91.189.92.201 80]
  Fetched 0 B in 0s (0 B/s)
  WARNING:root:file 'quantal.tar.gz.gpg' missing
  Failed to fetch
  Fetching the upgrade failed. There may be a network problem.

  Expected result:
  Ability to upgrade to either 12.10 -> 13.04 -> 14.04
  or upgrade directly from 12.04 -> 14.04 a direct upgrade path seems better.

  Additonal information of affected system:
  lsb_release -a
  No LSB modules are available.
  Distributor ID:	Ubuntu
  Description:	Ubuntu 12.04.5 LTS
  Release:	12.04
  Codename:	precise

  Also I am not the only one having this bug, see the following
  stackoverflow question: http://askubuntu.com/questions/504846
  /upgrading-from-12-04-3-lts-to-14-04-1-lts-failure this question
  wasn't posted by me, so this isn't only me.
