To fix the key error you have to import it with this command as root while on the internet:
rpm --import http://freshrpms.net/RPM-GPG-KEY-freshrpms
For the livna key:
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-livna
1. In installed f7 which has also inclided oo22. The problem is that his variant of oo22 has not anymore the possibilty (or I did not found it) to automatically install dictionaries. I have not found anymore the tag
"wizard - install new dictionary"
in this version !
In the fc6 I have installed manually oo22 and it was there ! It was moved in another place ????
Not sure what you are after here, maybe a little more information is required. If you want to change the default language go to main menu/administration/language (in KDE). To install more languages support, go to main menu/system/add/remove_software (in KDE) click on "languages" on the left side.
To edit grub, the file is /boot/grub/menu.lst
To access a local network, go to main menu/administration/network_configuration (in KDE).
