I've created a new VM from using the Quick Create function in Hyper-V on windows 10.

Once the VM is setup (I've picked language settings, created a password etc) I then tried to install Visual Studio Code and got the following error message: Unable to install "Visual Studio Code": too early for operation, device not yet seeded or device model not acknowledged.

From investigation this appears to be a snap problem.

Here's some details

snap --version:

snap    2.38
snapd   2.38
series  16
ubuntu  18.04
kernel  4.15.0-50-generic

Windows details: - Windows 10, version 1809, (OS Build 17763.437)

Things I've tried

1 - messing around with /var/lib/snapd/state.json

I tried the suggestion here: https://forum.snapcraft.io/t/cant-install-or-refresh-snaps-on-arch-linux/8690/28

Which looks like this:

sudo systemctl stop snapd
sudo cat /var/lib/snapd/state.json | \
    jq 'delpaths([["data", "auth", "device"]])' > state.json-new
sudo cp state.json-new /var/lib/snapd/state.json
sudo systemctl start snapd

However (and this is probably me being a Ubuntu noob) I can't get jq to install and I'm not sure exactly what it's doing so I can't do it manually.

2 - Using the Ubuntu 19 image

This apparently has the same issue.

3 - A colleague tried on his laptop

He had the same issue

4 - Reinstall snapd

I ran this: sudo apt install --reinstall snapd only for the install to get stuck at 67%.

5 - messing around with /var/lib/snapd/seed/seed.yaml

As per this bug: https://www.mail-archive.com/ubuntu-bugs@lists.ubuntu.com/msg5400922.html

I tried re-ordering the gtk-common-themes part and also removing the gnome-calculator part (rebooting after each change), this appeared to make no difference. The snap tasks --last=seed command still showed it getting stuck on the gnome-calculator task.

6 - headbutting the keyboard

I felt better but the issue persisted.

7 - using a non-quick start image

I downloaded a Ubuntu 18.04.2 ISO and used that. THIS WORKED (as in I could install Visual Studio Code and the snap commands looked healthy). However, it doesn't have all the nice hyper-v stuff so the screen res sucked, no copy and paste, mouse was very laggy etc...

I could install the various bits to make this image more hyper-v friendly but I have a feeling I'll never get as slick as the official one. If I can fix the snap on this one I think I'll end up with the best UX.

8 - THIS WORKS. messing around with /var/lib/snapd/seed/seed.yaml part 2

I removed a bunch of stuff from my /var/lib/snapd/seed/seed.yaml so it now looks like this:

snaps:
  -
    name: core
    channel: stable
    file: core_6673.snap
  -
    name: gtk-common-themes
    channel: stable/ubuntu-18.04
    file: gtk-common-themes_1198.snap
  -
    name: gnome-3-26-1604
    channel: stable/ubuntu-18.04
    file: gnome-3-26-1604_82.snap

And then did snap abort --last=seed followed by sudo systemctl restart snapd. Check snap tasks --last=seed - they should all be complete and you can do install snaps (such as Visual Studio Code).

Someone smarter than me will probably point out the horrible side affects this will cause.

    I can confirm that this helped, however what it does is it removes the packages not only from yaml, but also from system (they are not visible anymore)... What I did is simply reinstalled them back (some of them, the rest got reinstalled automatically) – Stefan Jarina May 18 at 16:49

Apparently the seed.yml file specifies apps to install on a fresh OS install.

If we remove the ones that are getting stuck and then manually install them, this works.

Steps:

1. Change your /var/lib/snapd/seed/seed.yaml file to look like this:

snaps:
  -
    name: core
    channel: stable
    file: core_6673.snap
  -
    name: gtk-common-themes
    channel: stable/ubuntu-18.04
    file: gtk-common-themes_1198.snap
  -
    name: gnome-3-26-1604
    channel: stable/ubuntu-18.04
    file: gnome-3-26-1604_82.snap

Basically I'm removing all the entries that caused the snap tasks to get stuck.

2. Abort the currently running snap tasks and restart the service:

  • snap abort --last=seed
  • sudo systemctl restart snapd
  • Keep running snap tasks --last=seed to see the progress of the snap tasks and wait for all the tasks to be "Done"

3. Manually install any apps that you removed from /var/lib/snapd/seed/seed.yaml, they might include:

  • gnome-calculator
  • gnome-characters
  • gnome-logs
  • gnome-system-monitor

The command to reinstall these is:

snap install gnome-calculator gnome-characters gnome-logs gnome-system-monitor

    Same issue remains on Hyper V Ubuntu 19.04 image. Problem solved with your solution above! It took be a while to find your post though as I was searching / googling with 19.04. Maybe you can add this version in question title for better index search. – Boud Jun 23 at 2:34
