ubiquity-dm fails with: FileNotFoundError: [Errno 2] No such file or directory: '/usr/lib/x86_64-linux-gnu/indicator-application-service'

[Ove Risberg]

I created a new LiveCD install image for Ubuntu-14.04 today and automatic-ubiquity does not work anymore.

In /var/log/installer/dm I can see this message:
ubiquity-dm: Failed with an exception:
ubiquity-dm: Traceback (most recent call last):
  File "/usr/bin/ubiquity-dm", line 716, in main
    ret = run(vt, display, username)

    ret = dm.run(*sys.argv[4:])

    raise child_exception_type(errno_num, err_msg)
FileNotFoundError: [Errno 2] No such file or directory: '/usr/lib/x86_64-linux-gnu/indicator-application-service'

The last LiveCD image I created have the /usr/lib/x86_64-linux-gnu/indicator-application-service file but not the one I created today.
The file belongs to the indicator-application package.
Version 12.10.1+14.04.20140117-0ubuntu1 have the file but 12.10.1+14.04.20140324-0ubuntu1 does not.

Ugly workaround:
ln -s /usr/lib/x86_64-linux-gnu/indicator-application/indicator-application-service /usr/lib/x86_64-linux-gnu/

Status changed to 'Confirmed' because the bug affects multiple users.

[Brian Murray (brian-murray)]

Could you please add the log file (/var/log/syslog) from the Live CD where you experienced this error?

[Jason Gerard DeRose (jderose)]

I can confirm this. This will happen if when you boot from the live CD, you press shift to get the menu, pick your language, and then "Install Ubuntu".

This does not happen if you "Try Ubuntu without installing", because in this case you are passed into the normal desktop session, rather than the special ubiquity-dm session.

This also effects OEM config... the first customer boot will be broken and they'll end up autologging into the "oem" user account.

Merge proposal for a fix here:
https://code.launchpad.net/~jderose/ubiquity/fix-1297312/+merge/212745

I confirmed this fixes the issue with regard to the customer first boot in OEM mode by manually editing /usr/bin/ubiquity-dm.

I haven't confirmed whether this fixes "Install Ubuntu" as that would require building a new ISO to properly test, something I don't have experience with with :)

Also, I haven't yet built ubiquity and and run its test, so there might be some unit test changes that are needed as well, dunno yet.

I can confirm that applying the following patch solves the problem for automatic-ubiquity:
https://code.launchpad.net/~jderose/ubiquity/fix-1297312/+merge/212745

I am applying this change in my "preseed/early_command" until the ubiquity package is fixed.

Confirming this issue on i386/amd64/amd64+mac

[Launchpad Janitor (janitor)]

This bug was fixed in the package ubiquity - 2.17.10

---------------
ubiquity (2.17.10) trusty; urgency=low

  [ Luke Yelavich ]
  * Set up atk label association for grub boot loader location combo box in
    advanced partition editor.
  * Add Super + Alt + S as an activation keystroke for the screen reader
    profile. This mirrors the same keystroke that can be used to activate the
    screen reader when in a Unity or GNOME desktop. The Control + S keystroke
    is still present for transitional purposes, so new users don't need to
    hunt for new information when they attempt to install trusty. It will be
    removed in trusty+1.

  * ubiquity-dm: 'indicator-application-service' =>
    'indicator-application/indicator-application-service' (LP: #1297312).

  [ Colin Watson ]
  * Resolve LABEL= and UUID= entries in /etc/crypttab into real devices
    before trying to run swapoff and test -b on them (LP: #1296697).
  * Automatic update of included source packages: flash-kernel
    3.0~rc.4ubuntu48, grub-installer 1.78ubuntu18, partconf 1.45,
    partman-jfs 43, partman-lvm 90, partman-newworld 32.
