uCareSystem Core is a lightweight utility capable of automating basic system maintenance activities, while on the other hand it can reduce the task of system administrators in a number of ways, saving a lot of time. It does not have any GUI and provides a pure command-line interface to perform activities.

Ubuntu has several utilities to perform system maintenance activities. Each tool has its own unique function and design. You can add a cron task to automate these tasks.

uCareSystem Core automatically refreshes the distribution repository, updates the list of available packages, unloads older packages, orphan packages, and older Linux kernels, and cleans up retrieved packages to save system disk space.
