const comment = `Hi @${context.actor}. Update of PR has failed. It can be due to one of the following reasons:
- I don't have permissions to update this PR. To update your fork with upstream using bot you need to enable [Allow edits from maintainers](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/allowing-changes-to-a-pull-request-branch-created-from-a-fork) option in the PR.
- The fork is located in an organization, not under your personal profile. No solution for that. You are on your own with manual update.
- There may be a conflict in the PR. Please resolve the conflict and try again.`;
