We’re releasing our first beta build of Insync for Flatpak! 
This is an early test release, so you may encounter bugs or desktop-integration issues. We’d appreciate your feedback, including your Linux distribution, desktop environment, and any relevant logs.
https://cdn.insynchq.com/test/Insync-beta-1.flatpak
flatpak install --user /path/to/Insync-beta-1.flatpak
flatpak run com.insynchq.Insync start
This is very welcome news
Mine is failing to start with the error message:
matkeith@bazzite:/var/home/matkeith/Downloads$ flatpak run com.insynchq.Insync start
F: Not sharing “/dev” with sandbox: Path “/dev” is reserved by Flatpak
I am using bazzite 44 with KDE
Correction: it was working but there is no system tray icon so I couldn’t see it. The error is just a notification that /dev can’t be passed and is being ignored. I provided Mia the details.
Finally! just one question…not sure if it’s going to be in conflict with my actual install…so to test it, it would be better in a distrobox I suppose? or what do you recommend?
Good question! Let me check with our engineers 
Very sorry for the long wait, @SolidCapo! Distrobox would be the recommendation
Hi y’all. TYSM for this! Coming from CachyOS the install instructions worked perfectly and Insync is fully functioning right now. 
I’ve just installed this on Fedora Kinoite 44 / KDE Wayland / NVIDIA 610.57.04 and I encountered a small problem: the flatpak beta exits with:
libnvidia-egl-wayland2.so.1: undefined symbol: wl_proxy_marshal_flags
From some poking around, /app/lib/insync/libwayland-client.so.0 does not export wl_proxy_marshal_flags. The Freedesktop 25.08 runtime copy does. My workaround:
flatpak override --user --env=LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libwayland-client.so.0 com.insynchq.Insync
That forces it to use host’s libwaylandclient.so.0 and InSync starts as expected. So basically the problem is a stale library.
I can put this in the bug reports channel if you like.
I’m extremely surprised (in a good way) to see a Flatpak beta.
For the moment, my Insync installation on Fedora 44 Silverblue is working just fine as a layered package.
As long as Insync Flatpak is in beta and my installation just works I don’t wanna change the flatpak installation.
If there is a migration plan for a later stable Flatpak version or I do have to install the OS from scratch.
Insync Flatpak will be the first applications to install!
Totally understandable, @Jonas! We greatly appreciate feedback from our users
Let me check in with our Linux Team where the stable Flatpak version is in our timeline 
And? Did you check? Got any answer? Or do we have to wait more than a year like for the update for the dolphin plugin?
The flatpak version is pretty useless ATM. It uses an outdated runtime and does not include the file manager plugins. So I would rather update the deb/rpm versions if I were you.
Hey @edisso10018, we do need to do a better job updating our users, thank you for this feedback!
I’m following up on the Flatpak release and we are also working on updating our deb/rpm versions.
Very sorry for the wait! The exact timeline to release Insync for Flatpak hasn’t been confirmed yet, but I have just followed up with our engineers once again. As for the other questions:
