** Description changed: **1) Ubuntu Version** - Kubuntu 25.10 (development/testing release) - + Kubuntu 25.10 **2) What I expected to happen** - The Sensors page in KDE Info Center should automatically load hardware sensor information such as CPU temperature, fan speeds, and voltages. + The Sensors page in KDE Info Center should automatically load hardware sensor information such as CPU temperature, fan speeds, and voltages. If the required backend tool (`sensors` from lm-sensors) is missing, KInfoCenter should either: - - install it automatically, or + - install it automatically, or - show a helpful message explaining what package to install. **3) What happened instead** The Sensors page fails to load and shows the error: "Could not load page content. The sensors tool is required to display this page, but could not be found." No guidance is provided, and the module is unusable. **4) Cause** - The Sensors module in KInfoCenter depends on the `sensors` binary from the `lm-sensors` package. + The Sensors module in KInfoCenter depends on the `sensors` binary from the `lm-sensors` package. However, the Ubuntu/Kubuntu packaging for `kinfocenter` does not install or recommend this dependency. After manually installing: - sudo apt install lm-sensors - sudo sensors-detect + sudo apt install lm-sensors + sudo sensors-detect the Sensors page loads and works correctly. This confirms the issue is caused by missing dependency handling in the package. **5) Steps to reproduce** 1. Install a clean Kubuntu 25.10 system. 2. Open Info Center. 3. Go to Devices → Sensors. 4. Observe the error shown instead of sensor data. **6) Why this is a bug** - The KInfoCenter Sensors module is non-functional out of the box on Kubuntu. + The KInfoCenter Sensors module is non-functional out of the box on Kubuntu. Because it requires a tool that is not installed by default, the page always fails unless the user manually installs lm-sensors. This is a packaging oversight affecting all Kubuntu 25.10 installs using KDE Plasma 6.4.x. **7) Suggested fix** One of: - - Add `lm-sensors` as a Recommends/Depends for the `kinfocenter` package, OR - - Modify the module to prompt the user to install lm-sensors, OR + - Add `lm-sensors` as a Recommends/Depends for the `kinfocenter` package, OR + - Modify the module to prompt the user to install lm-sensors, OR - Improve the error message with install instructions. **8) System Information** - Operating System: Kubuntu 25.10 - KDE Plasma Version: 6.4.5 - KDE Frameworks Version: 6.17.0 - Qt Version: 6.9.2 - Kernel Version: 6.17.0-7-generic (64-bit) - Graphics Platform: Wayland - CPU: 12th Gen Intel® Core™ i7-12700H (20 threads) - RAM: 16 GiB - GPU 1: Intel Iris Xe - GPU 2: NVIDIA GeForce RTX 3070 Laptop GPU + Operating System: Kubuntu 25.10 + KDE Plasma Version: 6.4.5 + KDE Frameworks Version: 6.17.0 + Qt Version: 6.9.2 + Kernel Version: 6.17.0-7-generic (64-bit) + Graphics Platform: Wayland + CPU: 12th Gen Intel® Core™ i7-12700H (20 threads) + RAM: 16 GiB + GPU 1: Intel Iris Xe + GPU 2: NVIDIA GeForce RTX 3070 Laptop GPU Laptop Model: HP OMEN by HP Laptop 16-b1xxx **9) Additional info** A screenshot of the error is attached.
