Ubuntu 23.10 has a firmware updater with the ability to [verify firmware] and [update checksums]. I'm not sure what these mean, but in pressing them, nothing seems to happen.
When I [update checksums] on an SD Card entry, I see "This will record the current cryptographic hashes as verified" (whatever that means) and again, nothing happens. Unless I maximise the screen and & then I see in the corner an unending "waiting for authentication".
Is this a known bug? nothing seems to update.
