Are you running low on disk space on your Ubuntu system or having trouble with software installations? Clearing the apt Cache might just be the solution you’re looking for. In this guide, I’ll show you how to free up space and fix conflicts by getting rid of cached package files.
We’ll go through simple steps using both terminal commands and a graphical method to clear apt cache in Ubuntu. Plus, I’ll help you tackle some common errors that might pop up while you’re clearing the cache. Let’s get your system clean and running smoothly by managing the apt Cache efficiently!
What is APT Cache and Why is It Important to Clear?
The APT cache is a part of your computer where it keeps information about the software packages available for installation and the software packages that you have already downloaded. This helps your computer know what software it can install and makes future installations faster because some files are already downloaded.
Why Should You Clear the APT Cache?
- Free Up Space: The APT cache can take up a lot of space on your computer because it stores many software files. Clearing the cache removes these files and gives you more space for other things.
- Remove Old Software: Sometimes, the cache holds onto old versions of software that you don’t need anymore. Clearing the cache gets rid of these old files and keeps your computer tidy.
- Fix Installation Problems: If a software installation didn’t complete properly, there might be broken files in the cache. Clearing the cache can help fix this problem because it removes the broken files and lets your computer try downloading them again.
How to Clear apt Cache in Ubuntu
To clear the APT cache in Ubuntu, you have two options: using the terminal or a GUI tool. In the Terminal, type sudo apt-get clean
to remove all cached files, or sudo apt-get autoclean
to delete only obsolete packages. For a GUI method, open the Disk Usage Analyzer, navigate to /var/cache/aptcache
, and manually delete the files. This approach lets you visually manage the space used by the cache.
Now, here are the detailed steps for these three methods and two more methods to clear apt cache:
1. apt-get Clean Command

2. apt-get Autoclean Command
The apt-get autoclean
command is similar to apt-get clean

- Open the Terminal application on your Ubuntu system and type the following command:
sudo apt-get autoclean
- The command’s output indicates the removal of obsolete package files, while necessary ones remain in the cache.

4. Manually Clear the Apt Cache
If you want to clear the Apt Cache manually, follow these simple steps to ensure the proper removal of unnecessary package files from your system:
- Head to the Terminal app on your Linux system and run the command below to go to the Apt Cache directory:
cd /var/cache/apt/archives
- Next, execute this command to list all files in the Apt Cache directory:
ls

option. From there click on Move to trash option.
3 Common Errors When Clearing apt Cache in Ubuntu
Clearing the apt Cache in Ubuntu is a routine maintenance task, but it’s not without its challenges. Understanding these errors can help you troubleshoot and resolve any issues that may arise during the process. Here are three common errors that you may encounter:
- 🚫 “Could not get lock /var/lib/apt/lists/lock” error: This error occurs when another process, such as an ongoing update or package installation, is using the apt system. It indicates that the apt Cache cannot be cleared until the conflicting process is completed or terminated. Ensure all package installations or updates have finished and close any package management tools running in the background.
- ⛔️ “Unable to lock directory /var/cache/apt/archives/” error: This error suggests that another instance of the package management system is currently using the apt Cache directory. It typically occurs when multiple package management tools or update managers are running simultaneously. To overcome this error, close any other package management applications and ensure that no updates or installations are currently in progress.
- 🔐 “Could not open file /var/lib/dpkg/status” error: This error indicates that the status file
dpkg package manager
is either missing or inaccessible. The status file is essential for managing package installations and updates, including clearing the apt Cache. To resolve this error, ensure that the file exists and has the appropriate permissions.
