Apt-get upgrade "kept back" question

[OBnascar]

obnascar@ubuntu:~$ sudo apt-get upgrade
Reading package lists... Done
Building dependency tree... Done
The following packages have been kept back:
gnome-cups-manager python-netcdf
0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded

Can someone please tell me why these packages would be held back ?

thay depend on another package that isn't being installed. use sudo apt-get dist-upgrade instead, it automatically installs nessecary dependencies.

dist-upgrade tells me the same thing

I have the same issue -- except mine's with a fresh Breezy-to-Dapper telling me 73 packages have been kept back.

Any ideas?

u need to update the package which apt-get tells u is being kept back. use update manager or synaptic instead

You are correct dolby, I used synaptic to update those two packages and now I do not get a "kept back" message.

thanks,

Well in my case the inconsistancy prevented X from installing -- so synaptic wasn't an option (And why would synaptic solve what apt-get and aptitude did not?). I just reinstalled.

For those who wish to avoid my situation in the future, I think it had something to do with installing automatix before the upgrade. Don't remember exactly what I did, but the only thing I'd touched between Breezy install and Dapper upgrade was Automatix.

This problem typically crops up every time I do an Ubuntu version upgrade. Sometimes, dist-upgrade works. In other cases, I've found that telling apt to remove the offending packages and then telling apt to install them again convinces it to find the required dependencies and resolves the problem.
