Problem upgrade 11.5 to 12

[FabrizioG]

Hi,
if i try to upgrade from the pannel I recive this error:

found inter-component dependencies conflict between 'msmtp' (will be installed: 1, request = REQ_INSTALL) and 'courier' (will be installed: 1, request = REQ_INSTALL) while trying to resolve REQ_INSTALL of component 'mod_fcgid' and 18 more change(s)
Error: Unable to resolve components request mode changeset due to inter-component dependencies. You possibly need to remove some of the conflicting components. Check '/var/log/plesk/install/autoinstaller3.log' for more details.


Tnx
Fabrizio
