cannot upgrade packages on server [SOLVED]

[Martijn van Es]

Hey all,

I have an Ubuntu server connected like it should be: only a power and network cable. It is a system without X (gnome / kde or wharever) only text.
I login to this system using ssh, i also upgrade using ssh.
first i run sudo apt-get update
then sudo apt-get upgrade (duh...)

whatever package is available for upgrade gets installed.

I get the following message after upgrade:
The following packages have been kept back:
bind9-host dnsutils libbind9-30 libisccfg30 linux-image-server linux-server
openssh-client openssh-server ssl-cert
0 upgraded, 0 newly installed, 0 to remove and 9 not upgraded.

Is there a way to upgrade these too without having to walk around with keyboard and monitor?
Thanks for your thoughts.

The following packages have been kept back:
bind9-host dnsutils libbind9-30 libisccfg30 linux-image-server linux-server
openssh-client openssh-server ssl-cert
0 upgraded, 0 newly installed, 0 to remove and 9 not upgraded.

Adept is telling you that these packages won't be upgraded at this time because doing so would cause breakage. This simply means that the upgrades to these listed packages have not yet been placed into the repositories. Just retry daily. When the held back packages get into the repositories, they will be upgraded as well.

Re: cannot upgrade packages on server

I have been getting these messages for over a month now. Are you still sure the reason is they are not in repositories?
I can imagine adept will not try to upgrade openssh-server when i am connected to the server through ssh. Is my imagination right or wrong?

Re: cannot upgrade packages on server

And if you try to install ?:

sudo apt-get install bind9-host dnsutils libbind9-30 libisccfg30 linux-image-server linux-server openssh-client openssh-server ssl-cert

or simulate

sudo apt-get install -s bind9-host dnsutils libbind9-30 libisccfg30 linux-image-server linux-server openssh-client openssh-server ssl-cert

"apt-get install" will install a package or upgrade a package if there is a new version available.

Any errors ?


To get a bit more information:

Simulation

sudo apt-get install -s <package>

man apt-get

-s, --simulate, --just-print, --dry-run, --recon, --no-act
No action; perform a simulation of events that would occur but do not actually change the system

Why

aptitude why <package>

or/and

aptitude why-not <package>

man aptitude

why, why-not
Explains the reason that a particular package can or cannot be installed on the system.
