how long does it need for the wallet to get synced ? , its kind of difficult to deduce that even if its doing anything ? , (no progress bar / indicator)
Do you mean Armory or Bitcoin Core? Bitcoin Core can take hours/days to sync up from scratch...
Armory will take a lot less time to sync, but it can only sync up to what Bitcoin Core has actually received... so make sure you run Bitcoin Core first and get it fully synced before attempting to start Armory.
