bitcoin-qt-0.8.1-beta installed on a computer. I also have another computer in which I'd like to share the same wallet.
First, for backup purposes, I have exported the wallet into a backup file and saved it on cloud (the wallet is encrypted!!!). Now I can retrieve this new wallet wherever I want. Given that the new workstation is secure enough to handle Bitcoins, I'd like to import the existing wallet file into the second computer.
I see options for exporting the wallet in bitcoin-qt, not vice versa.
I understand this question is very similar to How to import my wallet? but in my case I'm going to show my try-and-fail.
Copying wallet.dat wasn't successful onto a computer running
bitcoin-qt-0.8.1 for Linux (notice that it's not the beta)
bitcoin-qt -debug ************************ EXCEPTION: St13runtime_error CDB() : can't open database file wallet.dat, error 22 bitcoin in Runaway exception
The error is always the same. Even salvaging the wallet doesn't help, because my old addresses don't appear. I repeat, I transferred wallet.dat across different versions of bitcoin-qt.
I could think about dumping the private keys in the old client (which is still available and running, but not at my hand's reach), but I want to ask if there is a smart way to transfer an entire encrypted wallet from a computer to another.
In fact, the backup wallet option should be there for a reason, shouldn't it????
