Auto merge seems to not merge unless lockFileMaintenance is enabled

How are you running Renovate?

Self-hosted Renovate

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

Github - Renovate v11.4.0-full

Please tell us more about your question or problem

When configuring :automergeMinor:

{
  "$schema": "https://docs.renovatebot.com/renovate-schema.json",
  "extends": [
    "config:recommended",
    ":automergeMinor",
    "schedule:automergeOfficeHours",
   ],
   "autoApprove": true
}

Expectation: Renovate PRs would auto merge.

Actual: Renovate self-approves PRs and enables auto-merge but doesn't merge them.

My work around is to enable lockFileMaintenance:

{
  "$schema": "https://docs.renovatebot.com/renovate-schema.json",
  "extends": [
    "config:recommended",
    ":automergeMinor",
    "schedule:automergeOfficeHours",
   ],
   "autoApprove": true,
   "lockFileMaintenance": {
     "enabled": true, // this defaults to `false`
     "automerge": true // already set by `automergeMinor` so no impact here
   }
}

Then Renovate is able to actually merge the PRs.

I dug into the relevant source code but couldn't find any bug in the logic. Is this expected?

PS: Renovate is allowed to bypass PR branch checks.

Let's investigate why the GitHub auto-merge isn't completing after being enabled by Renovate. The issue is likely either a stale branch or a failing status check.

Sounds good! Let me know in case I can be of help. Thanks
