I noticed today that when I opened the update manager through the system settings in Ubuntu touch running on Nexus 7, it showed no updates. But the I ran the following two commands in the terminal:
sudo apt-get update sudo apt-get dist-upgrade
Certain updates started getting downloaded, and upon my consent, they were installed.
Why is this so? Why doesn't the over the air updates facility show the updates? I am running the latest daily build image of Ubuntu touch.
