¶ 6. What is the difference between LTS and non-LTS versions of Ubuntu?
- Answer: LTS (Long-Term Support) versions of Ubuntu are supported for five years and are more stable. Non-LTS versions are supported for nine months and include newer features, but may be less stable for production environments. The LTS versions are ideal for servers and users seeking stability.
- Answer: To upgrade between versions (e.g., from 20.04 LTS to 22.04 LTS), use the following command:
sudo do-release-upgrade
Ensure that your current system is fully up to date (sudo apt update && sudo apt upgrade) before performing the upgrade.

sudo apt --fix-broken install
sudo dpkg --configure -a
These commands try to resolve dependency issues and reconfigure partially installed packages.
¶ 9. What is a PPA, and how do I add/remove one?
- Answer: Ubuntu comes with a firewall tool called ufw (Uncomplicated Firewall). To enable it:
sudo ufw enable
To check the status:
sudo ufw status

sudo mount /dev/sdX1 /mnt
Replace /dev/sdX1 with the appropriate drive identifier and /mnt with the desired mount point.
- Answer: You can dual-boot Ubuntu alongside Windows by:
