I have since one week upgraded several PC to Ubuntu 14.04 Trusty Tahr.

I got several updates via the Software Updater, but I don't get updates from trusty-updates, although this repository is selected in the settings dialog:

{here was a nice screenshot of the dialog showing:

X Important security updates (trusty-security)

X Recommended updates (trusty-updates)

O Pre-released updates (trusty-proposed)

X Unsupported updates (trusty-backports)



Automatically check for updates: Daily

Where there are security updates: Display immediately

Where there are other udpates: Display weekly

Notify me of a new Ubuntu version: For long-term support versions

}

There are however several updates available:

$ sudo apt-get upgrade

I did not test them all, but all of which I tested come from trusty-updates:

$ apt-cache policy compiz nautilus update-manager

Updates from trusty-security are done however. So I don't know if that's a bug or something I misconfigured?

[UPDATE]:

• To answer comment below, I have some warnings / errors in ~/.cache/software-center/ as of today. Warnings like 'WARNING:main:no data, and even one ERROR - trying to repair DB failed. But they don't reproduce afterwards.


• Also, one of the package is compiz. I went to check the changelog on Launchpad, and noticed the following history page: https://launchpad.net/ubuntu/trusty/amd64/compiz. It says "Phased updates", "40% of users". Could this be linked to that? Is there a way to bypass this phased updates when using the Software Updater (as when using apt-get)?
