Satellite WebUI shows Capsule sync in 50% progress, despite no task is running

Environment

• Red Hat Satellite 6
  • External Capsule

Issue

Satellite WebUI shows Content Sync status with "Capsule is synchronized" text, but progress bar with 50% pending status.

Clicking to the progress bar, foreman tasks with the Capsule are shown - but all of them are stopped.

Is the Capsule synchronized? What task makes the progress bar to show at all?

Resolution

Identify a Capsule sync task with incomplete result, and fix that.

• Run inside foreman-rake console:

capsule = SmartProxy.unscoped.find(123)   # ID of the Capsule
organization = Organization.find(1)   # ID of the Organization
lifecycle_environments = capsule.lifecycle_environments.where(organization_id: organization.id)

capsule.active_sync_tasks
capsule.reclaim_space_tasks.where(:result => 'pending', :state => 'stopped')

• Either of latest 2 commands is expected to show some task with state=stopped but result=pending, like:

[#<ForemanTasks::Task::DynflowTask:0x00007fa31ee5f330

  user_id: 1,
  state_updated_at: Tue, 28 Apr 2026 00:00:47.768650000 UTC +00:00>]

• Fix result of the task (that has not been properly updated by dynflow at the task completion) - despite the task might completed successfully, it is safer to assume otherwise. Use proper task id from the id: "..." property:

task = ForemanTasks::Task.find('ac620a04-068a-4577-a494-6ce51893fe2f')
task.result = 'error'
task.save!

• Try accessing the WebUI page to verify the progress bar is gone.

Root Cause

dynflow has not properly set up result of the task, by some error. This caused capsule.active_sync_tasks contains an "unfinished" task that is interpreted by WebUI as an incomplete sync task, with unknown progress, hence estimated to 50%.
