AppImage and .deb doesn't word. Can't build on linux for linux

Bug: AppImage and .deb crash on startup (missing Rust symbol)

Description

The application fails to start both as an AppImage and when installed via .deb.
When launched from terminal, it throws a runtime error related to a missing Rust symbol:

Failed to lookup symbol 'frb_get_rust_content_hash'

When launched via GUI, the app exits immediately without any visible error.

---

Steps to Reproduce

1. AppImage

chmod +x OxiCloud-linux-x86_64.AppImage # set executable
./OxiCloud-linux-x86_64.AppImage # start app

2. .deb package

sudo apt install ./OxiCloud-linux-amd64.deb # install
oxicloud # start app

---

Expected Behavior

Application should start normally.

Actual Behavior

• Terminal: crash with Rust symbol lookup error
• GUI: silent crash (instant exit)

---

Error Logs

AppImage and .deb install

Unhandled Exception: Invalid argument(s): Failed to lookup symbol 'frb_get_rust_content_hash':
/tmp/.mount_.../liboxicloud_core.so: undefined symbol: frb_get_rust_content_hash

---

Additional Context

Error suggests a mismatch between:

• Flutter bindings (flutter_rust_bridge)
• Compiled Rust library (liboxicloud_core.so)

The symbol frb_get_rust_content_hash is expected but not present in the shared library.

Attempted Fix: Manual Build

Rust build

cd rust
cargo build --release

Build succeeds.

Flutter setup

flutter pub get
flutter_rust_bridge_codegen generate

Flutter build

flutter build linux --release

Fails with:

error: 'app_indicator_new' is deprecated [-Werror]

• Manual build currently blocked by unrelated Flutter plugin warning treated as error
