The correct option is The runner entered the organization's Default group and must be reassigned to the "ci-linux" group.

When you register a new self-hosted runner at the organization level it is assigned to the organization’s default runner group unless you explicitly place it in a different group during setup or move it afterward. If your team relies on a custom group then the runner will not appear there until you change its group membership in the organization runner settings.

The runner is still completing setup tasks and has not yet become available is not the most likely cause because registration is typically fast and the runner would still be listed under its initial group even if it were offline.

Your team lacks permission to view the runner group where you expect the runner is unlikely in this scenario because lack of permission would prevent viewing the group itself rather than hiding only this newly added runner. The more common cause is that the runner is in the wrong group.

Network connectivity problems are stopping the runner from showing as online in the group does not explain why it is missing from the group listing. Connectivity issues affect online status but do not prevent the runner from appearing in its assigned group.
