I have created nu.conf and ppcoin.conf in nu and ppcoin folders, However when i try to export the keys this Error appears every time:
Error: You must set rpcpassword=< password> in the Peercoin configuration file:
/home/xxxxx/.ppcoin/ppcoin.conf
If the file does not exist, create it with owner-readable-only file permissions.
I have to admit that i don’t know what is the rpcuser or the rpcpassword so i just used my ubuntu username and password since the wallets have no usernames, i even tried to write them with and without curly brackets, rpcuser=xxxxx or rpcuser={xxxx} , nothing worked!
