Running snapcraft always fails the first time

Hi all

Running snapcraft (using multipass) always fails the first time, subsequent runs always work. Just a minor inconvience.

snapcraft

Launching a VM.
Build environment was created with unknown snapcraft version None, cleaning.
delete failed: The following errors occurred:
instance "snapcraft-pi" does not exist
An error occurred with the instance when trying to delete with 'multipass': returned exit code 2.
Ensure that 'multipass' is setup correctly and try again.

Immediately after:

Is this with Ubuntu 18.04 Server on the Pi? If so are you using armhf or arm64 ?

If you run snapcraft clean; snapcraft does it reproduce?

This is done in a Ubuntu 18.04 Desktop in a VM I’m running, weirdly enough, I experience the same error in another Ubuntu 19.04 Desktop VM.

lsb_release -a

No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 18.04.4 LTS
Release:	18.04
Codename:	bionic

Running following, it indeed gives the error message, but then continues;

snapcraft clean; snapcraft

delete failed: The following errors occurred:
instance "snapcraft-beacon" does not exist
An error occurred with the instance when trying to delete with 'multipass': returned exit code 2.
Ensure that 'multipass' is setup correctly and try again.

if you run snapcraft clean in a source tree that has never been built before, where would a multipass instance come from ?

multipass creates build instances only if you build a snap, calling snapcraft clean in a virgin source tree i would actually expect that no instance in multipass exists yet so this message seems pretty correct to me … your subsequent snapcraft call then obviously succeeds as it should …

The error always occurs, regardless, it was suggested by @cjp256.

Is multipass strict or classic?

Output of snap list multipass will mention classic in the Notes column.

8

It is running under strict

snap list multipass

Name       Version  Rev   Tracking       Publisher   Notes

I also am hitting this error message a lot…

sometimes only reinstalling multipass fixes it for a while.
