Recovery will not work

[Ben Miller]

I am trying to run a recovery using the chromebook recovery utility and i works until I get to the "Create recovery image" part. When I click on "create now" it says "Unknown error: TEMP_DIR_CREATION_ERROR. Please try again." I know that I have 7.5 GB of storage on my USB, so I don't know what the problem is.

[Stephen Lin]

That error doesn't refer to a lack of space on the USB drive, it refers to an error creating a temp dir on the device that the USB drive is plugged into. The tool needs a temp dir to download and unpack the image into.

I tried that but it didn't work

Could you try to create the recovery usb from a differnt chromebook? You current chromebook may have a disk without enough free disk space.

Or on a Windows/MacOS or Linux Machine as there are recovery utilities for all 3 platforms

The whole point of me running a recovery is because I don't have very much disk space

[Stephen Lin]

If you're just trying to free up space on your drive you don't need to run recovery to do that. You can just go to the Files app, select the Downloads folder, and remove files that you don't want to keep anymore. If you really want to wipe your Chromebook and start fresh you can go to Settings and search for Powerwash and reset your device that way.

The recovery issue definitely looks like a drive space issue during the unzip process.

https://codesearch.chromium.org/chromium/src/chrome/browser/extensions/api/image_writer_private/unzip_helper.cc?sq=package:chromium&l=60

To check how much free space is left on your drive you can open up the Files app, click on the Downloads folder, then click the menu in the upper right corner. See attached screenshot. To be safe you'd need about 4GB of space available to be able to download and unzip the image file. Remove files as needed to free up space; you can copy to the Google Drive folder if you want to keep a copy of them in the cloud before deleting. Otherwise, if you're unable to free up space on the Chromebook then you will need to use another computer.

I don't have very much space becuse a non-working version of GalliumOS is taking it all up. I was told I can delete it by running a recovery

True, although it sounds like using recovery puts you in a
Catch-22...

Powerwash will also clean up storage space. Plus, it won't hand
you the Catch-22, it's faster and easier than recovery, and likely
less disruptive.

N.B. In case it's not clear: Both powerwash and recovery will
delete everything, and not just your problem stuff.

Richard : I'm not sure that's the case if someone has created a GalliumOS partition outside Chrome OS. 

If GalliumOS is "nonworking" then he can't delete it from within the partition. In that situation, I believe that a recovery is needed, but I could be wrong.

When going off the reservation, it's always prudent to make a recovery device before screwing things up, but many people don't think of this.

Ah. If the system has been re-partitioned, then powerwash won't
touch the non-standard partitions. A brief examination of the
Gallium docs does suggest it can repartition internal storage.
So, if the lack of space is because Gallium repartitioned the
stateful partition to be not big enough, well...

Yeah, if you need to get the internal storage back to a standard
partition layout, then recovery is required.

So, if it's not possible to clean up enough space from inside
Chrome OS, then the Catch-22 is well and truly on. Escape will
require some different system from which to create the recovery
device.

Ben,

The error message you're getting:

"Unknown error: TEMP_DIR_CREATION_ERROR. Please try again."

I think what's happening is what nt...@chromium.org and Selden Deemer pointed out above, your current system may have a disk without enough free disk space left to even temporarily create the recovery media.

I would suggest following Keith I Myers's suggestion using the Chromebook Recovery Utility on another system and creating the recovery media on a Windows/MacOS or Linux Machine as there are recovery utilities for all 3 platforms.

If I did that, how would my chromebook use that recovery media?

Same way as if the recovery stick were created on the Chromebook:
There's no difference whether the recovery stick is made with a
Chromebook, a Mac, a Windows system, or a Linux system.

The full instructions for creating a recovery stick on any platform
(and using the stick) are on the answer page for Chromebook recovery:

Thank you, I will try it soon.

[Ben Miller]

How do I download the chromebook recovery utility on a windows computer? It only lets me get extensions and themes from the chrome web store.
