...................... and im not using 202.62.73.208 ip so help me out from this

If it worked before, it'll work again. Just give it time. These things usually resolve themselves. If impatient, however, try selecting a different server in software sources.

BTW, do you still have Dapper installed? If not you should remove those entries.
