Re: No such file or directory when try to execute gsettings
Hi Sebastien, hi all :) Sorry for not answering before, but I don't have too much spare time and I spent the whole last week trying different things with my snap package. Sebastien, you pointed to me in the right direction, THANK YOU VERY MUCH! :) I have tryied snapcraft-desktop-helpers with gsettings interface and they did the trick! (with some problems that I think I'll described in another thread in order to not mess this one which i think is solved). So again, thank you very much for the help :) Best, Eloy 2016-09-08 15:38 GMT+02:00 Sebastien Bacher : > Le 07/09/2016 à 12:04, Eloy García (PC Actual) a écrit : > > > > > > I get your point and I think this is the real problem.

No, it's the other way around. Writting to dconf goes through a proxy service and the client talks to the server using dbus, so with the gsettings interface your snap can contact the desktop service and the write is done in the real-session's dconf database. Reading is done by opening a file in the user directory though and that doesn't work "out of the box" from inside the snaps because your code is going to see the private-snap-dir and not the real system one. If you use the desktop common part it has a hack for that though https://github.com/ubuntu/snapcraft-desktop-helpers/blob/master/gtk/launcher-specific#L79 > I have tried to search dconf database within snap confinement, but I > couldn't find it.

You should rather look on your desktop using e.g dconf-editor Cheers, Sebastien Bacher -- Snapcraft mailing list Snapcraft@lists.snapcraft.io Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/snapcraft
Re: No such file or directory when try to execute gsettings
Hi Sebastien! First of all, thank you very much for your suggestions :) I get your point and I think this is the real problem. I guess gsettings command line tool from the snap is storing the correct key/value inside the snap, but the "native" dconf database is not getting the new value, because the change wasn't made using "native" gsettings command line tool. I have tried to search dconf database within snap confinement, but I couldn't find it. Where should I search for it to see if the new value for the wallpaper was set there? P.S.: I've been searching within the tree which is in /snap/wallpaperdownloader/current with no luck.

Hey again, Did you figure it out? The gsettings command talk over dbus to the service which is in the user session, so the key should be written in your user db, the confined code in the snap doesn't get back the value since dconf does that by mapping a file from the user directory so it might mean your frontend might not get the new value of the key. Can you check from the outside the value of the key? If you use the shared desktop launcher it includes an hack to symlink the snap dconf db to the real one which should make reading work as well Cheers, Sebastien Bacher -- Snapcraft mailing list Snapcraft@lists.snapcraft.io Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/snapcraft
Re: No such file or directory when try to execute gsettings
Hi Sebastien! Thanks for your answer, but I forgot to say I tried gsettings and unity7 interfaces with no success. Nevertheless, I only put those interfaces in snapcraft.yml, but I didn't do anyting else (configurations, tweaks...). Adding more information, this is the script executed when wallpaperdownloader is launched. Maybe it is here where I should add some mappings to the "native" environment? #!/bin/sh # Only for packaging! # Script for snap packaging wallpaperdownloader application. It is not related to the code itself # Not good, needed for fontconfig export XDG_DATA_HOME=$SNAP/usr/share # Font Config export FONTCONFIG_PATH=$SNAP/etc/fonts/config.d export FONTCONFIG_FILE=$SNAP/etc/fonts/fonts.conf export HOME=$SNAP_USER_DATA java -jar -Duser.home=$SNAP_USER_DATA $SNAP/jar/wallpaperdownloader.jar Thanks again :) Eloy 2016-08-30 10:05 GMT+02:00 Sebastien Bacher : > Le 30/08/2016 à 09:20, Eloy García (PC Actual) a écrit : > > Any ideas or suggestions?

Re: No such file or directory when try to execute gsettings
Hi all again. As Sebastian Bacher suggested, I included gsettings binary within my snap package. This is the snapcraft.yaml file: name: wallpaperdownloader version: "2.2" summary: Download and manage your favorite wallpapers from the Internet description: WallpaperDownloader is a simple GUI Java based application for downloading and managing wallpapers from the Internet confinement: strict apps: wallpaperdownloader: command: wallpaperdownloader.sh plugs: [x11, network-bind, home] parts: # Pulls the code from the original source (master branch) wallpaperdownloader: plugin: maven source: . stage-packages: - libglib2.0-bin # It will copy wallpaperdownloader script into /bin/ # This script contains all the commands needed (sets env variables, launches the jar file...) to # execute the application exec: plugin: copy files: wallpaperdownloader.sh: bin/wallpaperdownloader.sh - Including libglib2.0-bin as stage-package, the application doesn't complain anymore about "No such file or directoy" because it finds gsettings binary on stage/usr/bin. Nevertheless, nothing happens when command line "gsettings set org.gnome.desktop.background picture-uri file://blablabla.jpg" is executed within the java code. I don't know how to "link" this command inside the snap with the native "command" and configuration files outside. The execution of this command should affect to the native environment and not the snap confinement created I guess, in order to change the current wallpaper in GNOME 3 or Unity. Any ideas or suggestions?

Re: No such file or directory when try to execute gsettings
Thank you very much for your quick answer. I want to implement this for other desktop environments, so I guess I have to include every binary I want to invoke, right? I'll give it a try.
