I'm not a server expert and so I'm experiencing some upgrade issues with Ubuntu. A little history: my Digital Ocean droplet was running Ubuntu 12.04 LTS, then a few months ago I upgraded to a newer HWE to continue to receive security updates for the 12.04. Recently I upgraded Ubuntu to the 14.04 LTS. Everything seems to be working fine except I'm not receiving any notifications that there are packages to be updated. Upon logging into my server the Message of the Day continues to display:

0 packages can be updated.
0 updates are security updates.

which just can't be right for 3 weeks now...?

running sudo apt-get update runs without error and sudo apt-get upgrade says 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

I have a feeling that my /etc/apt/sources.list was corrupted somehow after upgrading to the new HWE kernal and then the new LTS. Below are the sources listed currently. Does anyone see any issues with this list? any advice would be appreciated.

$ cat /etc/apt/sources.list

    • Yeah maybe...maybe not. Who knows? Maybe you could actually check and compare versions of packages which are installed on your machine with the available ones. Get your facts straight, so there is anything to work with.. By the way: "Maybe" (again: nobody knows) automatic updates are enabled on your machine.

    • My LTS systems haven't seen any updates in a few weeks either. This is normal. Don't worry. On the remote chance that DigitalOcean's mirrors are outdated or out of sync, just use the official us.archive.ubuntu.com mirrors.
    • Thanks Will, it's good to know I'm not the only one not seeing any updates lately. The timing of my upgrade over the holidays may have been the coincidence here.

Ubuntu LTS versions don't get many updates. In fact, the only updates you see in a LTS version are

  1. security updates
  2. bugfixes for major bugs (file loss bugs etc)

See https://wiki.ubuntu.com/StableReleaseUpdates#When for when exactly an LTS version gets updates.

    • Thanks Dominik. I think I've just been used to my older 12.04 server having what seemed like updates everyday. I'll just be satisfied all is good now ;-) Also appreciate the link, I'll keep tabs on that if I continue to see no changes.

Warm tip !!!
