# Troubleshooting ## Avalonia project does not run - Ensure `.NET 9 SDK` is installed. - Run `dotnet restore` and check NuGet feed access. ## Linux package build fails - Install `nfpm` via GoReleaser apt repo: ```bash echo 'deb [trusted=yes] https://repo.goreleaser.com/apt/ /' | sudo tee /etc/apt/sources.list.d/goreleaser.list sudo apt update sudo apt install nfpm ``` - Verify `nfpm --version` works and `nfpm` is in `PATH`. - Ensure publish output exists before packaging. ## Steam upload blocked unexpectedly - Check cooldown message and wait until retry window expires. - Ensure Steam client is running and user is logged in. ## Duplicate title bars - Confirm window settings in `MainWindow.axaml`: - `SystemDecorations="None"` - `ExtendClientAreaToDecorationsHint="True"` - `ExtendClientAreaChromeHints="NoChrome"` ## UI appears too large - Validate compact style values in `Styles/TerminalCore.axaml`. - Reduce headline and panel padding for high-DPI scenarios.
