I'm an amateur Linux user, so excuse my ignorance.

After upgrading to 15.04, the screen hangs on the Ubuntu loading image and then finally goes to a black screen with the following:

[ 1.595012] ACPI PCC probe failed.
Starting version 219.
Welcome to emergency mode
...

If I press on the down arrow during the Ubuntu loading image screen I get a long list of actions with an [OK] on the left but one with a [FAILED]. The [FAILED] one says this:

Failed to activate swap Swap Partition.
See "systemctl status dev-sda7.swap" for details.

At at the bottom of the black screen it says:

A start job is running for dev-disk-by\x2 duuid-ec5ce .... [string of letters and numbers].device

The above sentence has a timer after it which counts to 1 min 30 seconds and then goes to the screen above which starts with 

[1.595012]...

I have all my pictures and work stored on this laptop so I need to find a way to boot up!

Unfortunately none of the proposed solutions have worked. The IT support company that supports the business I work for got to the point of accessing the data but the home folder is encrypted and I don't have the key (which, sillily, is saved on my desktop). Data recovery specialists I called said they can't help, so it looks like I'll be losing the last few months of data on my laptop including photos of my 5 month old girl.

  • hi dan what is the system your running i.e. what type of processor , how much memory , and what kind of graphics cards is fitted ? is it a laptop or a desktop. –  Apr 28 '15 at 20:13
  • Hi Daron. Laptop XPS 13, Intel Core i5-3317U CPU@1.70GHz, 4GB RAM, Intel HD graphics 4000. Duel boot with Win 8. THe issue seems similar to this one: https://askubuntu.com/questions/614463/swap-doesnt-seem-to-mount-after-update/614470#614470 – Dan Richardson Apr 28 '15 at 20:33
  • which graphics card is it dan is it nvidia or onboard intel –  Apr 28 '15 at 20:36
  • H Daron, it's an onboard Intel. – Dan Richardson Apr 28 '15 at 21:54
  • ok from what i can see it is struggling to find the swap partition and also the hard drive information. Did you as part of the install use the lvm encryption ? when selecting what hard drive space. i would hazard a guess that you did. With this in mind i feel the best thing to do would be choose reinstall of 15 .04 burt not encrypting the hard disk space with lvm –  Apr 28 '15 at 22:34
  • please let me know if you have information stored on the laptop and we can discuss ways to get that information off before having to do a reinstall but given the error as in not finding the hard drive that could prove to be quite tricky. –  Apr 28 '15 at 22:39
  • Hi Daron. Thanks. yes, I did encrypt the home folder. How can I reinstall 15.04? If you're able to give basic instructions would be really appreciated. Right now I can only get to the "Welcome to emergency mode" screen. – Dan Richardson Apr 28 '15 at 22:40
  • Hi Daron, I do have information stored on the laptop. – Dan Richardson Apr 28 '15 at 22:48

This is a major disappointment and an incredible failure of Ubuntu. Updates should not be released if they cause major failures like this – Dan Richardson May 26 '15 at 16:20

I had some similar errors with my system, and I found that it was an error with some fstab entries (external drives that were no longer physically connected). I just commented them out and the system booted as usual.
