System is not getting upgraded to 12.10

[vichor]

Hi all,

I have tried several times to upgrade from my 12.04 to 12.10 and each time I get an error and the upgrade aborts.

I have run do-release-upgrade from the terminal with this result:

Upgrade could not be calculated

An unrecoverable error was detected while calculating the upgrade:
E:Unable to correct problems, you have held broken packages.

This may be due to:
* You are upgrading to a not yet released Ubuntu version
* You are using a not yet release Ubuntu version
* Non official software packages, not supplied by Ubuntu

If none of the above points apply, inform about this problem typing the command «ubuntu-bug ubuntu-release-upgrader-core» on a terminal.

Note: the above messages were partially in spanish and I have translated them. It's a free translation, though, and most probably will be different from the english ones, but I hope they will do anyway.

I have been updating my 12.04 installation with the new updates using the update-manager tool with no issues. Besides, apt-get install -f does not seem to detect any problem to be fixed. So I have no idea what could be preventing to upgrade to 12.10.

Any ideas anyone?

Thanks!

sudo gedit /etc/apt/sources.list

change each "precise" by "quantal", and deactivate extra archives( like ppa) untill upgrade is made (to avoid conflicts)

A possible reason to non upgraded might be that the system is set to only use LTS (watch synaptic tabs)

I am giving it a try... changed to quantal in sources.list and now running dist-upgrade. Let's see what happens ;)

It tool a while but finally it's updated. Now writing from quantal and no problem in sight (not counting the annoying blank screen stuff which I know more or less how to handle).

Thanks!!
