Comment 6 for bug 1925488

I just did a do-release-upgrade from impish to jammy (to check a different situation) and I've got the above message (with the "%s"), too:

  ┌────────────────────────┤ Pending kernel upgrade ├────────────────────────┐
  │ │
  │ Newer kernel available │
  │ │
  │ The currently running kernel version is 5.13.0-25-generic which is not │
  │ the expected kernel version %s. │
  │ │
  │ Restarting the system to load the new kernel will not be handled │
