Alfredo:

From the log message I think you have an older SchoolTool version installed in your second (target) VM. Could you double check that and let us know?

Hi Douglas,
thanks for your answer.
I check it, you're right, the versions are different but I've installed them in the same mode.
On the first machine I've SchoolTool 2.2.4
On the second I've SchoolTool 2.1.1
In which mode can I upgrade the second vm?
Thank you

You could try updating your second VM this way:

$ sudo apt-get update
$ sudo apt-get upgrade

That should get you the most recent software, including SchoolTool.

I've done it, but it doesn't upgrade it

If I understand correctly 2.1.1 is in the SchoolTool Owners "flourish" PPA.

Ubuntu 12.04 comes with SchoolTool 2.1 from the "universe" repository. In order to get 2.2 or 2.3 (the latest) you need the SchoolTool Owners "dev" PPA (http://book.schooltool.org/install-2_0.html)

Compare the /etc/apt/sources.list.d/ directories in both VMs. You should have some "schooltool-owners-..." files. I think the one in your first VM is pointing to "schooltool-owners/dev" while the second VM is pointing to "schooltool-owners/ppa".

Let us know.

Yes, this is the problem. I've veryfing it just now. Maybe I've solved.
The problem was on repository.
ppa:schooltool-owners/dev is it ok for Ubuntu 12.04 server?

Yes, ppa:schooltool-owners/dev will work on 12.04 although I think you'll get SchoolTool 2.3 now (https://lists.launchpad.net/schooltoolers/msg00206.html)

2.3 should fix your original problem though (related to evolution). Make a backup copy of your original database, just in case ;)

Ok perfect, I upgraded them.
Thanks a lot for your support and for the excellent project.
Now I'm looking for a backup manager for Data.fs
