Hi Micha, thank you very much!
I tested your packages on my plain buster installation. The sources list needs some tweaking: deb https://people.debian.org/~micha/PSD2/ experimental-buster-backports/ Did an: aptitude -t experimental-buster-backports install gnucash And additionally (wasn't sure which packages are needed): aptitude -t experimental-buster-backports install libchipcard6 libchipcard-data libchipcard-libgwenhywfar78-plugins libchipcard-tools With the new packages installed (incl. coping of aqbanking settings) I was able to fetch accounting data from my "Sparkasse" via HBCI with chipcard and ReinerSCT chipcard reader. One problem remains on my environment: The assignment of online (bank) account to gnucash account isn't stored correctly. In aqbanking management (via gnucash) the assignment can be done but next time I fetch accounting info I have to select (gnucash) account again. In the past, this assignment was only done/needed one-time. Thanks! Achim
