Software-center -> Edit -> Software source: change of server. Else perhaps the lock on your software database is still active.

Can you give the output of:

uname -a; lsb_release -a

Thanks

Can you also run:

sudo apt-get update; sudo apt-get -y upgrade && sudo apt-get --reinstall install nano

Thanks
