I don't know what to do with this. E: /var/cache/apt/archives/libreoffice-common_1%3a4.0.2~rc1-0ubuntu1~lucid3_all.deb: trying to overwrite '/usr/lib/libreoffice/program/officehelper.py', which is also in package libreoffice-emailmerge 1
It is hardly a problem with libreoffice.org website. Please ask for help on Ubuntu forums. For me it seems that the Python Mail Merge was a separate package in the past, and now it is installed with core. Remove libreoffice-emailmerge package first, then try again.
The reason I posted here is that the updater said it wasn't an ubuntu package. Thanks for the tip
