As for libreoffice, what is the output of "ls -l /home"? I will check the wbar issue once I import it again.
Did you re-import the wireless stuff, by making a file with a name of your choice, here it will be /home/tc/wireless?
Its contents:
wireless-tools
wireless-3.8.10-tinycore
firmware-iwlwifi
wpasupplicant
And importing it with the command:
import -f /home/tc/wireless
