I don’t know why, but it works now, after having run multipass launch snapcraft:core18 manually. Thanks @Saviq!
Building for core18: multipass issue
FWIW I think you may have hit our bug #569. It probably resolved itself over time, after our HTTP cache expired.

I’m experiencing the same thing now
$ multipass launch
launch failed: The following errors occurred:
venerated-snapper: shutdown called while starting
$ multipass launch snapcraft:core18
launch failed: The following errors occurred:
simple-garfish: shutdown called while starting
Hi @YamiYukiSenpai, could you please file this as an issue on our GitHub?
In the mean time, could you please also run:
$ multipass launch snapcraft:core18 -vvv
This will print more verbose logging to the console.
Thanks!
This happens to me a lot. I need to reboot and then ‘snapcraft’ command does not fail with the multipass error. Xenial.
I had similar error:
user@user# sudo snapcraft
Support for 'multipass' needs to be set up. Would you like to do that it now? [y/N]: y

Launching a VM.
launch failed: failed to start qemu instance
An error occurred with the instance when trying to launch with 'multipass': returned exit code 2.
Ensure that 'multipass' is setup correctly and try again.
Solved it by installing snapcraft from apt instead of snap
sudo snap remove snapcraft
sudo apt install snapcraft

That is not a solution. You’re papering over the problem by installing an old version of snapcraft. You are missing a lot of new functionality by doing this, of which only one part is the multipass integration.

Thanks @daniel, good to know.
Running multipass launch snapcraft:core18 -vvv and getting the error launch failed: failed to start qemu instance, reboot or sudo does not help and same error on core16.
Running it on nanopi Duo2 (armv7l processor architecture).
Where is your kernel from? If you are using a Ubuntu derivative, the kernel does not have KVM enabled and thus multipass does not work (see LP bug https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1783961, the bug is for ARM64, but AFAIK the same problem exists for armhf).
However, multipass should be outputting more helpful debug information, but perhaps the fix (see https://github.com/CanonicalLtd/multipass/pull/948) has not landed in the beta channel yet, can you try snap refresh multipass --edge and run multipass launch snapcraft:core18 -vvv again to see what it outputs?
After installing snap edge sudo snap install snapcraft --edge --classic and executing sudo snap refresh multipass --edge I run the command and got an error:
user@user$ multipass launch snapcraft:core18 -vvv

If snap edge isn’t good tell me and I will post another comment without the edge channel.
I am running
FriendlyCore (base on UbuntuCore), Kernel: Linux-4.14
One developer told me
You can build FriendlyElec’s Linux-4.14 by yourself according this wiki
If its help you better understand what kernel I am using.
Hi @guyluz11, it seems like your kernel does not have AppArmor support and we just enabled that on Multipass edge… This being a low-spec device, did you consider snapcraft --use-lxd to avoid the VM overhead?
@Saviq snapcraft --use-lxd return the error:
The LXD provider is offered as a technology preview for early adopters. The command line interface, container names or lifecycle handling may change in upcoming releases. Launching a container. An error occurred with the instance when trying to launch with 'LXD': The requested image couldn't be found. Ensure that 'LXD' is setup correctly and try again.
lxc list return empty table and sudo lxd init return The requested storage pool "default" already exists. Please choose another name.
Yes that is expected unfortunately, the cloud images that snapcraft pulls for lxd are not available on non-amd64 architectures, however you can still launch a container with lxd with the ubuntu:18.04 image and then run snapcraft --destructive-mode inside that container. Like this:
$ lxc launch ubuntu:18.04

This isn’t ideal, but as per Call for testing: snapcraft 3.4 we will have to wait until snapcraft switches what lxd images it uses in order for non-amd64 architectures to be supported with snapcraft managed lxd directly.

@ijohnson Thanks for the detailed answer.
I get this error on sudo lxc launch ubuntu:18.04
Creating the container
Error: Failed container creation: Get https://cloud-images.ubuntu.com/releases/streams/v1/com.ubuntu.cloud:released:download.json: Unable to connect to: cloud-images.ubuntu.com:443
Could it be because I use WiFi?
You shouldn’t see that issue just because you are using WiFi, but just to be clear is your device connected to the internet?
Restarted my internet router and now it works.
Now executing sudo lxc shell poetic-turkey return Error: not found
My device have 500Mb ram, will this be enough to run ubuntu:18.04 image in container?
poetic-turkey just happened to be the name of my lxc instance, yours will almost certainly be different. You can see the name of the instance that was launched with lxc list. The name in the first column is what you should use instead of poetic-turkey.
Ok now inside lxd shell:
root@bursting-sturgeon:~# sudo snap install snapcraft --classic
error: system does not fully support snapd: cannot mount squashfs image using "fuse.snapfuse":
fusermount: mount failed: Operation not permittedIn that case you need to install squashfuse in the container with:
$ sudo apt update && sudo apt install -y squashfuse
Didn’t help, tried sudo apt upgrade too but without success, getting the error error: system does not fully support snapd: cannot mount squashfs image using "fuse.squashfuse": fusermount: mount failed: Operation not permitted
