I have a 16.04 server on Digital Ocean that lists this when I ssh into it...
* Documentation: https://help.ubuntu.com * Management: https://landscape.canonical.com * Support: https://ubuntu.com/advantage 7 packages can be updated. 7 updates are security updates.
I have run
apt-get update and
apt-get upgrade many times and it has not gone away.
After I run the upgrade I see this as the last line...
0 upgraded, 0 newly installed, 0 to remove and 4 not upgraded.
