this bug is about a transition in the libaqbanking package, and has nothing to do with gnucash. gnucash in ubuntu/debian lacks HBCI support because of bug #5973. See the linked debian bugs as well.
short: you'll have to recompile your gnucash package for now. -- HBCI banking doesn't work due to dependency problems (aqbanking problem) https://launchpad.net/bugs/31789 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
