Hi ! NixOS newbie here 
Anyone know how to install and use seafile-client ?
nix-shell -p seafile-client
error:
… while calling the 'derivationStrict' builtin

Not building at the moment on unstable, switch to stable branch 25.05 for installing seafile. i think @heuzef is right with the linked issue.

There is a way to deploy only one package on stable branch ? Maybe with nix-shell ?
you can use an overlay and make it work again on unstable
nixpkgs.overlays = [
(final: prev: {
# Force override of the future derivation from any interpreter
future = prev.pythonPackages.future.overrideAttrs (old: {
meta = old.meta // {
broken = false;
unsupportedInterpreters = [ ];
};
});
# Optional safety net: override python313Packages.future too
python313Packages = prev.python313Packages.overrideScope (pyFinal: pyPrev: {
future = pyPrev.future.overrideAttrs (old: {
meta = old.meta // {
broken = false;
unsupportedInterpreters = [ ];
};
});
});
})
];
the other option would be to use the docker version of seafile
Thanks guy.
There is an another way waiting for the fix :
- Deploy the package
appimage-run
- Download the official AppImage
- Give it executable permission :
chmod +x Seafile-*.AppImage
- Run with
appimage-run Seafile-*.AppImage
Integration into the application menu (optional) :
~/.local/share/applications/seafile.desktop
[Desktop Entry]
Name=Seafile
Exec=appimage-run /path/to/your/Seafile-*.AppImage
Icon=/path/to/your/seafile.png
Type=Application
Categories=Utility;
Work well, effective way
