How to Install Ubuntu 25.10

---

Ubuntu is one of the most popular Linux distributions based on Debian, composed mostly of free and open-source software.
This guide will help you install Ubuntu 25.10 on your server via CrownPanel.

Login to CrownPanel

---

Login to your CrownPanel account.

To start the installation, first, mount the Ubuntu 25.10 ISO.

To mount the ISO, click on the CD-ROM tab and then select the "Ubuntu 25.10" ISO from the drop-down menu and click on the Mount button (It will take 2–3 minutes).

Once the ISO has mounted (the Task Log tab will show the status of the task), navigate to the Power Control tab and perform a Reboot task on the server.

Next, switch to the VNC tab, and launch VNC to start the installation.

If VNC doesn't show the Ubuntu 25.10 installer, please click on CTRL + ALT + DEL from the VNC console to send a reboot.

Start the Installation

---

When the server boots from the mounted Ubuntu ISO, you'll see the Ubuntu installer.
Choose the Try or Install Ubuntu Server option to start the installation process.

Select your preferred language and click on Continue.

If prompted, allow the installer to update (recommended).
Next, select your keyboard layout and click Done.

Select the installation type (e.g., "Ubuntu Server") and click Done.

Configure the network connection (DHCP or static) and click Done.

You can go ahead with DHCP (press ENTER) unless you need a static IP setup.

If required, you can configure a proxy here — otherwise, leave it blank and proceed.

Next, keep the default mirror address that Ubuntu detects for your location.

Disk Setup

---

For simplicity, we will go with automatic partitioning.
Select Use an entire disk and click Done.

Review the partition summary and proceed.

Confirm to erase the selected disk (this will remove existing data).

Profile Setup

---

Enter your user information — this will be the login credentials used after installation.

Select to install the OpenSSH server, which allows remote login after installation.

You may choose additional server snaps/packages here — we’ll keep it minimal for this guide.

Installation Process

---

The installer will now begin installing Ubuntu 25.10 on your disk.

Once the installation is complete, click Reboot.

Unmount the ISO

---

After reboot, Ubuntu will prompt you to remove the installation medium.

To unmount the ISO:

• Go back to CrownPanel,
• Select the CD-ROM tab,
• Click on Unmount.

Then, return to the VNC console and press ENTER to continue the reboot.

Your VPS will now boot into your new Ubuntu 25.10 installation.

Login to Ubuntu

---

Once the system has rebooted, you can log in using the credentials you set earlier.

✅ Done! You have successfully installed Ubuntu 25.10 on your VPS.
You can now configure and use your Ubuntu 25.10 server as needed.
