This question already has an answer here:
I decided to try out Ethereum and installed Ethereum Wallet for Linux. I created an account and sent some ETH from my Coinbase account. I can see the balance in Etherchain, but my Ethereum Wallet account has a balance of 0.
Ethereum Wallet shows: 2 peers ~1.6mil blocks left 6%
Is this typical of an Ethereum application? Are there better alternatives for Linux?
