After logging in, you can check for and apply new updates with:
$ sudo apt-get update
$ sudo apt-get dist-upgrade

This is great, thanks!
Can you add this to a shell script, then add it to a cron?

Hi thanks for the help.
I have one doubt, once I used the sudo shutdown -r now command how do I start it again? -
Basically my doubt is that whether sudo shutdown -r now command works as a shutdown command or a restart command??

This worked for me when...
$ sudo su # apt-get update # apt-get upgrade... did not.
The only message I got was:
The following packages have been kept back:
linux-generic linux-headers-generic linux-image-generic
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded

I found the answer to this so I'm posting the solution for anyone else with the same issue.
You need to use apt-get dist-upgrade It will not upgrade to a new Ubuntu release. It will just install available updates for the Ubuntu release you already have installed.
http://askubuntu.com/questions/215267/will-apt-get-dist-upgrade-upgrade-my-system-to-newer-version
Further:
" dist-upgrade in addition to performing the function of upgrade,
also intelligently handles changing dependencies with new versions
of packages; apt-get has a "smart" conflict resolution system, and
it will attempt to upgrade the most important packages at the
expense of less important ones if necessary. So, dist-upgrade
command may remove some packages. The /etc/apt/sources.list file
contains a list of locations from which to retrieve desired package
files. See also apt_preferences(5) for a mechanism for overriding
the general settings for individual packages. "http://askubuntu.com/questions/194651/why-use-apt-get-upgrade-instead-of-apt-get-dist-upgrade

# apt update
# apt full-upgrade
# reboot
An "apt upgrade" will install most package upgrades. In my experience, the last few stragglers tend to be kernel related; "apt full-upgrade" handles those guys.
Have another answer? Share your knowledge.
try with: sudo apt-get update
I'm having the same problem.
When logging in, I see
138 packages can be updated.
68 updates are security updates.
I do sudo apt-get update
I am prompted for and provide the password.
Then, a bunch of stuff scrolls by and some is downloaded.
I logout, and then again login.
And, alas, I see the very same
138 packages can be updated.
68 updates are security updates.
Is this normal? This seems a serious issue, since apparently all those security
updates are not being installed.
sudo apt-get updateonly updates the information about what packages/versions are available. You need to follow it withsudo apt-get upgrade. Then restart your droplet:sudo shutdown -r now. Hope that helps!Update won't do it, you need to Upgrade, then reboot the server. Shutdown with a time delay is polite if others may be logged in doing things, otherwise save time (and keystrokes) by just using reboot.
sudo apt-get upgrade
sudo reboot
