Update Ubuntu 10.04

  • 772

I keep getting this message when I logged into my server in AWS EC2 via ssh

I think this is called MOTD

43 packages can be updated.
22 updates are security updates.

but I have already done 

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

I have also restarted my instance.

Please advise.

  1. This is coming from the MOTD (Message Of The Day). The MOTD is pieced together from the commands in /etc/update-motd.d. The specific message comes from running /etc/update-motd.d/90-updates-available.

    I have seen this happen on systems where after running sudo apt-get update and packages are kept back

    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.

    The message can mean several things e.g. there may be dependency issues etc. there is more on this in the APT HowTo.

    I have managed to stop the messages with 

    sudo aptitude update
sudo aptitude safe-upgrade

    If that doesn't work then the link above does give advice on how to track down the problem packages.

    Another one of these "fine" Ubuntu-bugs... Check Ubuntu Bug #634387: https://bugs.launchpad.net/ubuntu/+source/sysvinit/+bug/634387

    I deleted the files "/etc/motd.tail" and "/etc/motd.tail.old" and did a logout / login to re-genereate a propper /etc/motd.

  3. I was seeing this same issue on Ubuntu 14.04

    I edited /etc/pam.d/sshd

    and changed this line
    session optional pam_motd.so motd=/run/motd.dynamic noupdate

    by removing the noupdate

    now the banner displays correctly.

  4. Run the following command:

    sudo /usr/lib/update-notifier/update-motd-updates-available --force

  5. After numerous failed attempts, the recipe that works for me is based on Kimi and Lex Miller:

    $ sudo aptitude safe-upgrade
$ sudo /usr/lib/update-notifier/update-motd-updates-available --force

  6. Try this: 

    sudo apt-get install unattended-upgrades

sudo dpkg-reconfigure --priority=low unattended-upgrades

sudo dpkg-reconfigure -plow unattended-upgrades -f noninteractive -p critical
