[Bug 944945] Re: Ubuntu alternate AMD64 install ISO fails, tasksel dialog culprit

[Todd Howe]

I tried 'manual selection' on my most recent attempt to tackle this,
which launched an interface for aptitude.

It looked like just a shell installation was queued for installation
there.

The evidence might suggest the Ubuntu package list isn't being loaded
into the installer, but I'm not sure how to verify that.

Bootup addendum, possibly useful? Once you choose nothing at the tasksel dialog, bypassing the error:
- An installation with no LVM fails on bootup by displaying a flashing cursor on tty7
- An LVM installation displays 'mountall: Disconnected from Plymouth'  on tty7

Title:
  Ubuntu alternate AMD64 install ISO fails, tasksel dialog culprit

Status in “debian-installer” package in Ubuntu:
  New

Bug description:
  12.04 Precise Beta 1 64 bit alternate install fails to install
  succesfully, getting hung up on the 'tasksel' process.

  Selecting any of the options (OpenSSH, Desktop) produces the
  Installation Step Failed dialog.

  Selecting none of the options results in completion of the install,
  HOWEVER it will not boot... the boot process hangs...

  When the boot process stops, hitting CTRL-ALT F7 displays a flashing
  cursor at the home position.

  Hitting CTRL-ALT F1 and logging in to tty1 reveals there's been
  nothing installed to ~ other than .bashrc .bash_logout, .cache and
  .profile

  Discussions seen elsewhere (eg; Ubuntu forums) reveal this bug was in
  Oneiric as well, blocking installs. There was some discussion that
  tasksel is only supposed to be on the server install ISO and not the
  Desktop alternate ISO?

  I've tried both the guided encrypted LVM install as well as the guided
  full disk with no encryption with the same result.

  (Also since no networking or removable media works, I can't get any
  logs off the machine. I'll grep search it to help the developers
  though)

  This on an Acer Aspire 1410 netbook.
