Now that Ubuntu 7.04 runs smoothly on my machine, I gave online banking via HCBI PIN/TAN (a popular German standard) another try, because the according aqbanking libs have been updated. I tried the command line aqhbci-tool and received some useful feedback, but couldn't get it to work. Then I started the graphical frontend qbankmanager and found a built-in wizard that supported my every step in creating a new account, connecting to the banking server, and retrieving my account information. Perfect! I will try some more sophisticated apps like KMyMoney, GnuCash, or Hibiscus later, but for now I'm happy.
For the sake of keeping my installation as clean as possible: aqhbci-tool listmedia returns two old entries that do not funtion. Can anyone please tell me how to remove them? There seem to be only parameters for adding new users/accounts, but not for removing them.
