Hi,
thank about the response :-)

but this not resolve my problem,
when I run the command
dpkg -r calendar
I get the following error:

dpkg: dependency problems prevent removal of calendar:
mp-fremantle-002-pr depends on calendar (= 0.8-3+0m5).
dpkg: error processing calendar (--remove):
dependency problems - not removing
Errors were encountered while processing:
