Override-build behavior changes for V3?

bashfulrobot · March 18, 2019, 7:41pm

Hi there,

I’m updating budgie-welcome to Snapcraft V3 - and to start I am just attempting a build of the existing snapcraft.yaml. I hit an error where the override-build section is failing (missing files - rebuild-translations.sh in this case).

So I jumped into the image with snapcraft --debug, and I cannot find the needed files as reported in the error. I was looking at /home/multipass/parts/budgie-welcome/build (as per docs).

In that directory I see:

.
├── hooks
│   ├── install
│   ├── post-refresh -> install
│   └── remove
├── scripts
│   └── welcome-wrapper
└── ubuntu-budgie-welcome_source.tar.bz2

Now the content I am trying to target (and that had previously built) sits in the top level scripts folder (in our repo):

(This is a pruned tree - just to exhibit where the script sits in the repo compared to the snap folder).

Am I missing something that changed?

Thank you in advance.

This is odd. I added base: core18 to the same YAML.

Now it fails out with:

An error occurred when trying to execute 'sudo -i env SNAPCRAFT_HAS_TTY=True snapcraft snap' with 'multipass': returned exit code 2.

Googled around for that error (to no results). HM.

Lin-Buo-Ren · March 20, 2019, 9:16pm

Try running snapcraft with the SNAPCRAFT_ENABLE_DEVELOPER_DEBUG=yes environment variable.

bashfulrobot · March 20, 2019, 9:17pm

Is this run within multipass? Or on the host? (Assume host)

Lin-Buo-Ren · March 20, 2019, 9:18pm

Should be run on the host IIRC.

bashfulrobot · March 20, 2019, 9:19pm

Confirmed. I should have just tested.

Appreciate your time.

bashfulrobot · March 20, 2019, 9:26pm

Weuuffff. That’s verbose.

If I read this correctly, it seems like my snapcraft does not want to play nice with multipass.

~~You snapcraft seemed to be still running in V2 mode…?~~

UDPATE: Oh you’re just starting the port, not already ported to V3

Saviq · March 20, 2019, 9:40pm

@bashfulrobot can you paste the full log somewhere? The extracts you posted miss the meat of the problem.

Does multipass launch work OK?

bashfulrobot · March 21, 2019, 8:45pm

@Saviq I did a quick test, and it does in fact work (pulled an image and spun up a VM).

AS for the log - that was all of the output (terminal). Is there a better way to generate a more verbose log?

Lin-Buo-Ren · March 24, 2019, 7:23am

journalctl --unit snap.multipass

I’ll give it a go. Appreciate the insight.

Was this ever resolved?

I’m running into this on MacOS and getting same error, “snapcraft.internal.build_providers.errors.ProviderExecError: An error occurred when trying to execute ‘sudo -i env SNAPCRAFT_HAS_TTY=True snapcraft snap’ with ‘multipass’: returned exit code 2.”.

I tried the “export SNAPCRAFT_ENABLE_DEVELOPER_DEBUG=yes” and got the following:

Replying to self.

I have a partial fix for this and that is to not let the build system shutdown between tries. I do:

$ multipass stop --cancel snapcraft-duplicity

after each run and it’s stayed stable for many builds now.
