Call for testing: Snapcraft 7.2.0

jocado · October 27, 2022, 3:50pm

Cross posting - this seems relevant: Snapcraft 7.2 depends on snapd socket at runtime

Cheers, Just

mr_cal · October 27, 2022, 11:21pm

@EndrII, would you be so kind to test my fix?

You can install it with snap refresh snapcraft --channel=latest/edge/pr-3965

I believe the issue is related to a limitation with Multipass snap only having access to the user’s home directory due to snap confinement.

mr_cal · October 27, 2022, 11:23pm

Thanks for the report, @jocado. I’ll look into that tomorrow.

EndrII · October 28, 2022, 8:39am

Yes, after your fixes, Snapcraft works great. Thank you

Attempting to run any snap builds in Docker (using https://github.com/snapcore/snapcraft/blob/main/docker/Dockerfile as a base) fails with Snapcraft 7.2.3:

index ad6b0949..c69a5c51 100644
--- a/snapcraft_legacy/internal/common.py

@@ -384,6 +384,12 @@ def get_snap_config() -> Optional[Dict[str, str]]:
         )
         return None

+    if is_process_container():
+        logger.debug(
+            "Not loading snap config because snapcraft is running in a container"
+        )
+        return None
+
     snap_config = SnapConfigOptions(keys=["provider"])
     snap_config.fetch()

which at least allows the snapcraft commands to complete successfully if I modify that file locally.

mr_cal · October 31, 2022, 12:48pm

Thanks @gward-tridium. @jocado reported the same issue here. I’m working on a fix.

mr_cal · November 1, 2022, 8:25am

@EndrII - Your issue with running snapcraft + multipass is now fixed and released on the channel latest/candidate

EndrII · November 1, 2022, 8:36am

Thank you, but I will wait for stable release )

mr_cal · November 2, 2022, 10:05am

And 7.2.4 is on stable!

andrewsomething · November 2, 2022, 9:51pm

We’re seeing the same issue as reported by gward-tridium with Snapcraft v7.2.4.

Let me know if there’s anything we can do to help debug.

mr_cal · November 3, 2022, 9:44am

@andrewsomething, I have a fix here, would you be able to test it using channel=edge/pr-3971?

andrewsomething · November 3, 2022, 1:35pm

@mr_cal I can confirm that resolves the issue for me. Thanks for the quick work!

gward-tridium · November 3, 2022, 1:58pm

@mr_cal The fix on edge/pr-3971 fixes our issues as well. Thanks for taking a look!

mr_cal · November 3, 2022, 2:29pm

Great! Thank you @gward-tridium, @andrewsomething, and @jocado for the good feedback and testing. This fix is now released to the channel latest/candidate

jocado · November 3, 2022, 3:58pm

Great - thank you for your support

Was I too soon in using latest/candidate?

Ah wait, might be caused by me using jammy as UBUNTU arg?

mr_cal · November 4, 2022, 1:01pm

UBUNTU=Jammy is not the problem. From your logs, the first call to snapctl works but the second does not. Curious behavior, I can’t reproduce that or figure out how it happened.

Regardless, the fix is simple and I’ll have prepared today.

Can you provide some details on how you are doing setup, execution, or provide the snapcraft.yaml? It looks like a core22 snap being built non-interactively. I’d like to write regression tests to not break docker builds again.

Update 1: PR is here and can be tested on channel edge/pr-3974

Update 2: Released as version 7.2.7 and should be available on the channel candidate soon

hardeves94 · November 4, 2022, 3:36pm

I will test it asap. I did adapt the Dockerfile as well, added core22 to it.

mr_cal · November 10, 2022, 9:41pm

Thanks @hardeves94! Your subsequent error should be fixed shortly with https://github.com/snapcore/snapcraft/pull/3982.

P.S. You can add code blocks by adding a line with 3 backticks (`) before and after the code.
