Flatpak

From GnuCash
Jump to: navigation, search
Languages Deutsch

Flatpaks are bundles which besides the program also contain all required libraries. Use cases:

  • If your Linux distribution is too old to offer all required libraries but has Flatpak support, you can install a recent released version of GnuCash from the FlatHub repository.
  • If a developer asks you to test a patch, you can use a nightly version from our Flatpak repository.

Known Issues

  • We do not ship the Python Bindings,
  • no direct report printing, but printing them to file and direct printing of checks works and
  • an only on Ubuntu derivates watched bug that causes guile to attempt to recompile all scm sources:
    ldconfig: /app/lib/libguile-2.2.so.1.3.0-gdb.scm is not an ELF file - it has the wrong magic bytes at the start.
    
    ;;; note: source file /app/share/guile//2.2/ice-9/eval.scm
    ;;;       newer than compiled /app/lib/guile/2.2/ccache/ice-9/eval.go
    :
    
Workaround:
cd /var/lib/flatpak/app/org.gnucash.GnuCash/
sudo find . -name '*.go' -exec touch '{}' ';'
  • To use smart cards, at least Flatpak 1.3.2 needs to be installed on your system. Complain against your distribution if they do not offer it.

Installation

You can configure many package managers like Gnome Software or KDE's Discover to at least install or update Flatpaks from Flathub, but on this page we will use the more powerful flatpak command line tool. The examples to install flatpak itself are written for Debian (in Buster Flatpak is already included, for Stretch and Jessie backports exist) and its derivates like Ubuntu.

Hint
For other distributions replace apt* <command> by your preferred commandline software managment tool and its command, i.e. for many rpm based distributions
zypper install flatpak
FlatPak.org offers Instructions for several distributions.

Regular releases from flathub.org

You can have both the regular, currently GnuCash 4.2, and beta branches installed at the same time.

Betas (GnuCash 4.9xx) are previews and only released in the last months before the next main version, see Release Schedule.

For Stable Releases
# Install FlatPak (on debian based distributions, others have to replace 'apt-get install'):
sudo apt-get install flatpak
# Register FlatHub repository:
sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
# Install GnuCash ...
## for all users:
sudo flatpak install flathub org.gnucash.GnuCash
## or only you:
flatpak install flathub org.gnucash.GnuCash
# Run GnuCash:
flatpak run org.gnucash.GnuCash
Tip
To get the most recent version, run each quarter year (see Release Schedule):
flatpak update
For Unstable (i.e., beta) Releases
Do the process for stable releases, but register, install, and run as follows.
# Register:
sudo flatpak remote-add --if-not-exists flathub https://flathub.org/beta-repo/flathub-beta.flatpakrepo
# Install
flatpak install --user flathub-beta org.gnucash.GnuCash
# Run
flatpak run --branch=beta org.gnucash.GnuCash
Downgrading
It can't be done from the average package manager, but it can be done from the command line. It's a two-step command:
flatpak remote-info --log flathub org.gnucash.GnuCash # list all commits in the repo
flatpak update --commit=HASH org.gnucash.GnuCash # checkout commit HASH in the repo
The only gotcha is that if you have more than one repo that has org.gnucash.GnuCash I haven't found a way to tell the command which repo you want to manipulate. It looks flatpak will to update all installed versions. If you have one app installed from our nightlies and one from flathub, the above command will fail as only the flathub repo will have the proper commit hash.

Test version from gnucash.org

Warning
Save your data before using test versions!

Often you can find test versions on the build-server. They come in two flavours:

Maint
Version 4.2 plus all recent bug fixes, but no new features: code.gnucash.org/builds/flatpak/maint/
Master
Version 4.2 plus new features, but bug fixes can be delayed a few days: code.gnucash.org/builds/flatpak/master/
Tip
The file names in these directories can be used in the example below after trimming the „gnucash-“ prefix and „.flatpakref“ suffix.

The current version contains Aqbanking 6.1.0 (PSD2 capable of online banking via FinTS/HBCI (german) protocol; date of this information: 2020-02-20).

sudo apt install flatpak  #install Flatpak
# register repositories:
sudo flatpak remote-add --if-not-exists gnucash https://code.gnucash.org/builds/flatpak/gnucash-nightlies.flatpakrepo
sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
flatpak --arch=x86_64 remote-ls gnucash  # show all packages
# output should be:
# org.gnucash.GnuCash
# org.gnucash.GnuCash.Debug
# org.gnucash.GnuCash.Locale
sudo flatpak --arch=x86_64 install gnucash org.gnucash.GnuCash//maint-C3.8b-163-g0e6c9e219-D3.8b-15-g0479ece  # <-- change version here!
flatpak run org.gnucash.GnuCash  # start program
Note
flatpak --arch=x86_64 is only required, if you have a 64-bit processor with a 32-bit OS.

Tips

Maintenance

You should — also if no new GnuCash version was announced — sometimes run
sudo flatpak update  # sudo is only required for systemwide installations
to look for updated components of your Flatpak environment. That might look like:
        ID                                    Zweig  Op  Remote   Download
 1.     org.freedesktop.Platform.GL.default   19.08  u   flathub   < 85,1 MB
 2.     org.freedesktop.Platform.VAAPI.Intel  19.08  u   flathub    < 8,7 MB
 3.     org.gnome.Platform.Locale             3.34   u   flathub  < 322,2 MB (partial)
 4.     org.gnome.Platform                    3.34   u   flathub  < 320,4 MB
 5.     org.gnome.Sdk.Locale                  3.34   u   flathub  < 325,8 MB (partial)
 6.     org.gnome.Sdk                         3.34   u   flathub  < 663,9 MB

Proceed with these changes to the user installation? [Y/n]:
It is primarly important, if you reported a problem about which the Gnucash-Developers said, its cause lies not in Gnucash but one of the by Flatpak installed Gnome libraries. But also for security reasons you should keep your environment up to date.

Getting Console Output

In case of trouble get the console output:
flatpak run org.gnucash.GnuCash
or even better
flatpak run org.gnucash.GnuCash --logto stdout

The latter will print all logs to the console rather than to an inaccessible trace file.

Using Command Line Tools

To call command line tools like aqbanking-cli, the following opens a command shell inside the sandbox of GnuCash.
flatpak run --command=sh org.gnucash.GnuCash

Inside you can call related shell commands for Online Banking like aqbanking-cli… or Online Quotes gnc-fq-* etc.

The following enters the GnuCash sandbox and runs a gnucash-cli command in a single line (using the example of getting price quotes). This can be useful for automation, i.e. creating a modern systemd timer or a classical cron job to get price quotes on a regular basis.
flatpak run --command=gnucash-cli org.gnucash.GnuCash --quotes get /path/to/file.gnucash

Notice the order of the arguments!

SQL Connection

Use 127.0.0.1 instead of localhost. The latter will tell the mysql client to use unix file sockets. These are not permitted by default by the flatpak sandbox. You can enable permissions for this on your gnucash flatpak, though I don't know offhand where the unix socket is located. You'll have to figure that out first (it will look like a file on your system somewhere) and then use the flatpak override commmand to tell it to allow access to that file for the org.gnucash.GnuCash package.

Using 127.0.0.1 on the other hand will force mysql to use a real network connection. Those are not restricted in the GnuCash flatpak.

More details: FlatHub GnuCash issue 17

Granting Access to Other Resources

Each flatpak is a sandbox. To allow it e.g. access to your USB drive, execute
sudo flatpak override org.gnucash.GnuCash --filesystem=<path-to-your-usb>
