Gnucash cannot be installed

Is there an estimation when gnucash will be available? It is the only program which was not installable in the last weeks since I got my librem5. But not being able to work with my accounting data is a problem to switch completely to librem.

But anyway: Thanks a lot for your great work.

I solved my problem using flatpak

$ sudo apt-get install flatpak
$ sudo flatpak install --from https://flathub.org/repo/appstream/org.gnucash.GnuCash.flatpakref
The remote ‘flathub’, at location https://flathub.org/repo/ contains additional applications.

Then I allowed GnuCash access to the place where I store my files
$ flatpak override org.gnucash.GnuCash --filesystem=/mnt/qnap/home/partner
$ flatpak run org.gnucash.GnuCash /mnt/qnap/home/partner/Gemeinsame-Dokumente/Buchhaltung/aktuell/BH_2017.gnucash

The first time I started the app I got the error ldconfig: /app/lib/libguile-2.0.so.22.8.1-gdb.scm is not an ELF file - it has the wrong magic bytes at the start.
