Can you confirm a few details:
1) Was this a factory installed system?
2) If so, was this the version of Dell Recovery included on your system?
3) What's the model # of the system on which this failure occurred?

Indeed, this was a fresh from the factory system.

Dell Precision M3800.

I should also note that the originally posted stack trace was the result of running an identically-versioned copy of dell-recovery that I downloaded to confirm what I was seeing with the factory-installed version. The stack traces were identical.

Mario Limonciello (superm1) wrote :

OK. Can you post your /var/log/dpkg.log? I'd like to check what got installed and removed in the factory process.

Mario Limonciello (superm1) wrote :

Here's a package that should fix the bug (and should have been installed from the factory image). Hopefully from your log we can make sense of what went wrong.

2) I have applied all updates provided by the Software Updater; other than that, this is the version of Dell Recovery included on my system.
3) Dell Precision M3800.

dell-recovery 1.32~somerville6 was already installed, but I also tried the .deb attached to this bug report with no improvement.

My /var/log/dpkg.log is attached.

lemmuh (lemmuh) wrote :

Unfortunately my /var/log/dpkg.log is no longer available since I needed to use the system, so I proceeded with wiping it after coming up with an alternative recovery mechanism. Hopefully the log provided by acallan provides the information you need. Dell support actually provided me with a recovery ISO for this specific system (Precision M3800 + Ubuntu 14.04) in case anyone needs it.

Mario Limonciello (superm1) wrote :

@lemmuh, please don't post that ISO publicly. Anyone else who has this problem and we can't get it sorted out please contact Dell support and they'll share the ISO image to you.

I think this might be a side effect of an unexpected missing utility partition that we expected at factory install.

Can you please provide the output of this command:
# sudo lsblk -o name,mountpoint,label,size,uuid

Hopefully that will identify what's happening.

Here's a temporary fix that should get the media generated for you. Once I can see what partitions are on your system I'll know if it can be a permanent fix or not.

Of course, it wasn't my intention to make this publicly available.

OK thanks, just making sure :)

I'm also affected by this bug, also on a Dell Precision M3800 (new in February, 2015).

Here's my output from sudo lsblk -o name,mountpoint,label,size,uuid

OK. Here's the correct fix then. It seems that one of our expected partitions labels has changed. If you apply this fix it should work properly. We'll work on getting it fixed in the Dell repository too.

Thanks, Mario!

Patch applied, recovery .iso successfully built :)

Also verified that that works.

Applied the patch; it works for me also.

Will the fix also be made in 14.04? I plan to remain on LTS.


Mario Limonciello (superm1) wrote :

The fix for 14.04 will be coming via the Dell repository and factory
install. The dell-recovery in the Ubuntu repositories is a bit outdated,
so the newer version won't likely qualify for an SRU.

It will come in via regular APT updates on Dell factory shipped systems.
