Clearing your system cache in Ubuntu is a simple process that can help improve the performance of your system. When you browse the internet, your web browser saves a cache of the websites you visit to load them faster next time. Similarly, Linux systems like Ubuntu also keep a cache of various things such as applications and package archives to speed up their loading times.
While caches are helpful for quick loading, they can also consume your system’s memory over time. It’s important to clear out unnecessary cache data, also known as junk files, to keep your system fresh and running smoothly.
If you’re using Ubuntu version 14.04 or 16.04 and want to clear your system cache easily, follow these steps:
Install Ubuntu Cleaner:
Open the Terminal and run the following commands:
sudo add-apt-repository ppa:gerardpuig/ppa
sudo apt update
sudo apt install ubuntu-cleaner
Once the installation is complete, launch Ubuntu Cleaner from the Unity Dash by searching for its name and clicking on its icon.
In the Ubuntu Cleaner interface, you’ll see options to delete various caches, including browsers, Software Center caches, apt-cache (which stores downloaded package archives), and thumbnail cache for quick directory loading.
You can also use the utility to delete old kernels, unwanted packages, and package configurations. To check the space occupied by a specific cache, simply click on its entry in the tool’s interface.
To delete a cache, select the entry and click on the “Clean” button at the bottom-right corner of the interface.
It’s important to note that caches serve a purpose and deleting them indiscriminately can affect the performance of your system. Before deleting any data, consider your options carefully. For example, deleting the cache of an unused app can free up space, but deleting the cache of a frequently used app may affect its speed and responsiveness.
Ubuntu Cleaner is a useful tool for managing system caches and maintaining system performance. It’s a branch of the Janitor module of the now-deprecated Ubuntu Tweak tool, aimed at providing similar functionality to the Ubuntu community.
In conclusion, maintaining a balance between clearing caches and preserving system performance is essential for computer users. While it’s important to manage cache sizes, deleting every cache may not always be necessary. Use tools like Ubuntu Cleaner wisely to optimize both speed and storage on your Ubuntu system.
