Investigation: Spread test failures are due to craft_providers snapd initialization issue by Copilot · Pull Request #2509 · canonical/charmcraft

Copilot · 2025-12-06T03:19:43Z

This PR documents the investigation into spread test failures that show "daemon is stopping to wait for socket activation" and "Failed to wait for snap refreshes to complete" errors in smoketests/reactive and smoketests/different-dir.

Investigation Results

The failures occur inside LXD containers created by the craft_providers library during charm builds, not on the host system where spread tests run. The error happens when craft_providers sets up base LXD containers and runs snap watch --last=auto-refresh? inside those containers while snapd is in a transitional state.

Root Cause

The issue is in the craft_providers library's container initialization code (specifically in craft_providers/base.py in the _disable_and_wait_for_snap_refresh method around line 616). The spread.yaml prepare sections only configure the host system (Google Cloud instances) and cannot affect the internal setup of LXD containers created by charmcraft during builds.

Bug Report for craft-providers

A comprehensive bug report has been prepared and documented in craft-providers-bug-report.md that should be filed at: https://github.com/canonical/craft-providers/issues

The report includes:

Complete error details and stack traces from the failing builds
Root cause analysis of the snapd transitional state issue
Three proposed solutions with detailed code examples:
1. Retry logic with exponential backoff (recommended)
2. Enhanced snapd readiness checks before snap operations
3. Graceful degradation with warnings
Impact assessment on charmcraft and other craft-providers consumers
Steps to reproduce the issue

Recommended Fix

The bug report recommends implementing retry logic with exponential backoff in the _disable_and_wait_for_snap_refresh method to handle the transient "daemon is stopping to wait for socket activation" error gracefully. This approach would allow the container initialization to succeed even when snapd is temporarily in a transitional state.

The fix needs to be made in the craft_providers library, as this is outside the scope of what can be fixed through spread.yaml modifications in the charmcraft repository.

Original prompt

Fix Spread Test Job Failure: LXD Snap Refresh

Recent workflow runs (see logs) show that spread tests are failing due to errors like:
error: daemon is stopping to wait for socket activation
craft_providers.lxd.errors.LXDError: Failed to wait for snap refreshes to complete.
This problem occurs during container setup when waiting for snapd refreshes in LXD containers, causing build/test failures in jobs such as smoketests/reactive:stable and smoketests/different-dir.

Solution

Modify the setup steps in .github/workflows/spread.yaml to ensure snapd is running and healthy before spread/charmcraft commands are executed in the test container. This can be done by adding commands to restart snapd and wait for its readiness inside the container.

Example fix (snippet):

Add before running charmcraft/spread tests:
- name: Ensure snapd is running in the LXD container
  run: |
    lxc exec <container-name> -- systemctl restart snapd
    lxc exec <container-name> -- snap wait system seed.loaded
Replace <container-name> with the actual name of the LXD instance used in the workflow setup.

@copilot that didn't fix it. https://github.com/canonical/charmcraft/actions/runs/19982288239/job/57318843865?pr=2509#step:5:332

The issue is occurring inside LXD containers created by craft_providers during builds, not on the host system. The error "daemon is stopping to wait for socket activation" happens when craft_providers sets up the base container and runs snap watch --last=auto-refresh?.

My changes to spread.yaml only affect the host (Google Cloud instances), but the actual failure is happening inside containers that charmcraft creates via the craft_providers library. This is a craft_providers issue, not something that can be fixed in the spread.yaml configuration.

The fix would need to be in the craft_providers library itself, specifically in how it handles snapd initialization inside containers. This is outside the scope of what can be addressed through spread.yaml modifications.

…config The snapd failures occur inside LXD containers created by craft_providers during builds, not on the host system. The spread.yaml changes only affect the host and cannot fix container-internal issues. Co-authored-by: lengau <4305943+lengau@users.noreply.github.com>

@copilot open a descriptive bug report in craft-providers

I've created a comprehensive bug report in commit 5a881da. The report is saved in craft-providers-bug-report.md with complete details including:

Error messages and full stack traces
Root cause analysis
Three proposed solutions with code examples
Impact assessment

The report should be filed at: https://github.com/canonical/craft-providers/issues/new

The recommended fix is to add retry logic with exponential backoff in the _disable_and_wait_for_snap_refresh method to handle the transient "daemon is stopping" error.
