| PR_BODY_CONFLICTS='# :warning: UPSTREAM CHANGES. DO NOT MERGE MANUALLY. | |
| This automated pull request was created by the [Sync from Upstream (create)](${{ github.server_url }}/${{ github.repository }}/actions/runs/${{ github.run_id }}) workflow. | |
| There are updates from upstream to be merged, but our local changes conflict with the upstream changes so we need to resolve the merge manually. | |
| To merge the changes manually, use the following commands: | |
| ``` | |
| # Checkout the branch | |
| git checkout sync-upstream-${{ github.run_number }} | |
| # Reset the branch to main | |
| git reset --hard origin/main | |
| # Pull changes from upstream | |
| git remote add upstream https://github.com/actions/runner-images.git | |
| git fetch upstream | |
| # Merge the changes | |
| git merge -m "Merge commit '${{ steps.merge.outputs.upstream-sha }}' from actions/runner-images" ${{ steps.merge.outputs.upstream-sha }} | |
| # Solve the conflicts and continue the merge | |
| git merge --continue | |
| # Push the changes to the branch | |
| git push --force-with-lease origin sync-upstream-${{ github.run_number }} | |
| ``` | |
| Once you have merged the changes successfully, please get somebody else to review and approve this pull request. The bot will then handle merging the changes to `main`. Do not merge manually. | |
