How to resolve a full disk issue in Ubuntu system?

When the disk space on the Ubuntu system is running low, you can use the following methods to address the issue:

1. Clean up temporary files and cache: Use the command sudo apt-get clean to clear the apt cache, utilize sudo apt-get autoremove to delete unnecessary software packages, check the size of the apt cache using sudo du -sh /var/cache/apt/archives, and clean up temporary files by using sudo rm -rf /tmp/*.
2. Remove unnecessary log files: Use sudo du -sh /var/log to check the size of log files, and delete any unnecessary ones.
3. Clean up junk files: Use “sudo du -sh /var” and “sudo du -sh /home” to check disk space usage, and delete unnecessary files.
4. Compress or remove large files: Use sudo find / -type f -size +100M to search for large files, then you can choose to delete or compress these files.
5. Utilize the Disk Usage Analyzer tool: Install and use the Disk Usage Analyzer tool to view the disk space usage, identify large files or folders taking up space, and proceed with cleaning or moving them.
6. Expand disk space: If the above methods do not solve the problem, consider expanding disk space by either adding more hard drive capacity or expanding existing hard drive partitions to address insufficient disk space.
