How to Mount and Unmount ISO Files on Ubuntu Linux Using the Terminal

Downloading an Ubuntu Server ISO

• 🌐 First, navigate to the Ubuntu website to download an example ISO file.
• ⬇️ The video demonstrates downloading the Ubuntu Server version due to its smaller file size (around 3 GB) compared to the desktop version.

Creating a Mount Point

• 📁 To mount the ISO, a mount point directory needs to be created.
• 🛠️ This is achieved using the command sudo mkdir /mount/iso, where /mount/iso is the chosen directory name.

Mounting the ISO File

• 💻 The ISO file is mounted using the terminal command sudo mount -o loop /path/to/your.iso /mount/iso.
• 🔗 The -o loop option treats the ISO file as a virtual disk.
• ⚠️ A read-only warning is expected and normal for ISO files, indicating successful mounting.

Verifying and Unmounting

• 📄 The contents of the mounted ISO can be verified using the ls command in the mount point directory.
• 📤 To unmount the ISO, use the command sudo umount /mount/iso.
• ✅ After unmounting, the mount point directory will appear empty again.
