Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I'm using this munin plugin : http://exchange.munin-monitoring.org/plugins/apt_ubuntu/details

The server is an ubuntu 10.04 up to date.

So..

This is my munin server, which on its own munin graph shows me a red alert on System, its an alert of "3 Security Upgradable Packages".

But does packages are kept back.

What Should I do to make the alarm disapear?

root@fbmmu01:/home/admmarc# **apt-get update**
Hit http://ppa.launchpad.net lucid Release.gpg
.......[some repos which show no error]
Reading package lists... Done
root@fbmmu01:/home/admmarc# **apt-get upgrade**
Reading package lists... Done
Building dependency tree       
Reading state information... Done
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.
root@fbmmu01:/home/admmarc#

Thanks.

Ok, from the munin-exchange plugin page itself, on the comments I found this:

Written by C. Alex Roeber on 'Oct. 25, 2010, 18:54.

Remember that apt-update will not do the kernel or a few other security packages. run apt-get upgrade and it will tell you which are not being upgrade. Then run apt-get install on them.

goodluck

So I've done as it says:

apt-get install linux-generic linux-headers-generic linux-image-generic

And after this:

root@fbmmu01:/home/admmarc# /etc/munin/plugins/apt-ubuntu 
security.value 0
updates.value 0
proposed.value 0
backports.value 0
other.value 0
total.value 0

So, its just becouse kernel packages don't care about upgrade, they need to be installed.

its untrue that "apt-get update" will not do the kernel. The reality is that it won't install packages that aren't already installed and won't delete pacakges which are installed. If upgrading a package requires changing the list of installed pacakges, you can use "apt-get dist-upgrade" –  stew Jan 13 '11 at 4:21
