Update Manager notifier visible when packages are locked

I can't confirm this. Since you locked the packages, have you right-clicked on the Update Manager icon and clicked on 'Check for updates'? Once I do this, the icon disappears when all the 'upgradeable' packages are locked

You're right. I checked for updates and the icon disappeared.

This is just a little confusing though, shouldn't it disappear after you click on it once and it can't present any updates?

Anyway, close if you'd like.

I think you're right - this is a bit confusing. I would expect the icon to disappear after locking the packages too, so I'll confirm this.

Steps to reproduce:
-Lock all upgradeable packages in Synaptic

What do you expect to happen?
-Update notifier icon should disappear from the notification area once all upgradeable packages are locked.

What actually happens?
-After locking all upgradeable packages in Synaptic, the Update notifier icon remains in the notification area. It doesn't disappear until you right click on the icon and click 'Check for updates'.
