Screenshot 1
SUMMARY
When attaching a new docking station using thunderbolt, a notification appears
asking the user to "Authorize Now" or "Authorize Permanently" the device
(Screenshot 1). Selecting any of these two options results in a new
notification showing an error message, slightly different depending on which
was option was selected. Screenshot 2 is when selecting "Authorize Now" and
Screenshot 3 when selecting "Authorize Permanently".
In both cases, the error seems misleading since the device is shown as
connected and trusted in System Settings, and everything works as expected
(external monitor, ethernet, etc.). The "Authorize Now" also does not work as
expected since the device is permanently trusted. This can be tested by
disconnecting the device, connecting again. No notification is shown asking
again for authorization and the thunderbolt device works directly without any
user intervention.
In addition, the list in System Settings -> Thunderbolt is, in my opinion,
confusing for several reasons. There is no button to delete devices, only a
button to "Revoke Trust". But if this button is clicked, the device is deleted
from the list. What if the user wants to simply remove permanently trust on the
device, so that authorization has to be given manually each time the device is
connected?
STEPS TO REPRODUCE
1. Go to System Settings -> Thunderbolt and revoke trust on all devices
2. Attach a docking station using thunderbolt and select "Authorize Now"
3. Disconnect thunderbolt, and connect again
OBSERVED RESULT
Thunderbolt is authorized and trusted permanently despite selecting "Authorize
Now".
EXPECTED RESULT
It is not clear and not explain in the System Settings menu what is the
difference between "Authorized" and "Trusted". This should be explained
somewhere. Also, the hint says "An unstrusted device needed to be manually
authorized each time it is connected to the computer", but the user is never
asked if a device is trusted or not, only if it should be authorized now or
permanently. With that model, I guess "Authorize Now" -> "Untrusted", and
"Authorize Permanently" -> "Trusted", but this is also not the observed
behavior as shown above.
