Can anybody help me please. I´ve no more idea at the moment
You've got a package conflict.
It looks like the version of zoneminder you've already got on your system is "1.28.0+nmu1" and the version you are trying to install is "1.28.1-6~bpo8".
Because the suffixes are different, your system sees two completely different, unrelated packages, rather than a newer version of the same package.
Consequently, the package manager is (correctly) refusing to install the new version because it would overwrite files you've already got on your filesystem.
The most straightforward approach here would be to be to uninstall zoneminder 1.28.0 completely, and then install zoneminder 1.28.1.
Make sure and backup anything you don't want to get deleted during this process.
very similar thing happened to me when i used apt-get and manually edited sources.list from a su console on the desktop....i got the extra backports boot option
in the same enviorment i used synaptic instead and it flew thru from a fresh install...
