Original GitHub issue: https://github.com/AppFlowy-IO/AppFlowy/issues/3662

Bug Description

Since the update that just dropped for the flatpak version (0.3.4), AppFlowy won't launch anymore. Nothing happens, just the wobbling icon to say it's loading and nothing appears. If I launch it from the command line (flatpak run io.appflowy.AppFlowy), all I get is this error:

AppFlowy: error while loading shared libraries: libnotify.so.4: cannot open shared object file: No such file or directory

If I rollback to the previous version it works again.

How to Reproduce

Update AppFlowy flatpak to 0.3.4.
Launch it, it should fail to launch.

Expected Behavior

AppFlowy should successfully launch.

Operating System

Fedora-KDE 38

AppFlowy Version(s)

0.3.4 (Flatpak)

Screenshots

No response

Additional Context

No response

I have the same issue, when attempting to launch the software from the terminal, I get the same error. Fedora 38 Workstation Edition.

Please try to install the libnotify manually.

sudo apt-get install libnotify4

sudo dnf install libnotify

And I have updated the version to 0.3.5. It should be available on Flathub tomorrow.

This shouldn't be required to run a flatpak. The whole point of this packaging format is to resolve dependencies separately from the system.

I checked and libnotify was already installed on my system.

Agreed. So I added libnotify4 as a dependency in flatpak.yml.
