Linux Operating System UBUNTU 25 _ INTEL DZ68DB Motherboard _ OPPO Reno 5G smartphone _ Why Linux UBUNTU 25                 PC/Desktop  cannot recognize or detect the the OPPO Reno 5G    smartphone when they are both physically connected  to each other via a  "USB to Type-C"   cable ?

 

 

Question 

Hi Copilot , when I connect my OPPO RENO 5G smartphone to a PC/Desktop which is running UBUNTU 25 Operating System via a "USB to Type-C" , meaning one end of the cable which is a Type-C is connected to the OPPO RENO 5G smartphone and the other end of the cable which is a USB 2.0 is connected to the USB port of the PC/Desktop which is running UBUNTU 25 Operating System . Copilot , with all these connections in place , and with the help of the Nautilus File Manager , which is the default File Manager for the UBUNTU 25 Operating System , I should be able to see all the contents and all the files and all the folders inside my OPPO RENO 5G smartphone ......... BUT THE PROBLEM IS .......... THIS IS NOT HAPPENING ??? Copilot , what do you think could go wrong ? This is not happening when my PC/Desktop is running the Windows 8 Operating System ? Copilot , could you please help me with this problem ? THANKS.

Got it — thanks for laying out the details so clearly. Let’s troubleshoot this step by step. The fact that your OPPO RENO 5G connects fine on Windows 8 but not on Ubuntu 25 points to differences in how Android phones communicate with operating systems.

Here are the most common causes and fixes:

🔍 What could be going wrong

  • USB mode not set to File Transfer: By default, many Android phones connect in "Charging only" mode. On Windows, a pop‑up often prompts you to switch, but Ubuntu won’t. You need to manually select "File Transfer (MTP)" on your phone after plugging it in.
  • Missing MTP support on Ubuntu: Ubuntu requires the mtp libraries and GVFS (GNOME Virtual File System) to talk to Android devices. If these packages aren’t installed or configured, Nautilus won’t show your phone.
  • Permission issues: Sometimes the phone is detected but not mounted due to user permissions. Running lsusb in Terminal can confirm if Ubuntu sees the device at all.
  • Cable compatibility: Some USB‑C to USB‑A cables only support charging, not data transfer. Windows may tolerate flaky cables better, but Ubuntu is stricter.
  • Nautilus/GVFS bug: Occasionally, Nautilus doesn’t refresh or mount the phone correctly. Restarting Nautilus or using an alternative file manager (like Thunar or KDE Dolphin) can help.

🛠️ Steps to fix

  1. Check phone USB mode
    • Connect your OPPO RENO 5G → swipe down notifications → tap USB options → select File Transfer (MTP).
  2. Install MTP support on Ubuntu
    Open Terminal and run: 
    sudo apt update
sudo apt install mtp-tools gvfs-backends gvfs-fuse
    Then reconnect your phone.
  3. Test detection
    Run: 
    lsusb
    If you see your OPPO device listed, Ubuntu recognizes it.
  4. Try another file manager
    If Nautilus still doesn’t show it, try sudo apt install dolphin and check if it mounts there.
  5. Try another cable/port
    Swap cables or use a different USB port to rule out hardware issues.

⚡ Why it works on Windows but not Ubuntu

Windows has built‑in MTP drivers, so Android phones usually "just work." Ubuntu relies on open‑source MTP libraries, which sometimes need manual installation or configuration. That’s why you see the difference.

Would you like me to walk you through installing the MTP packages on Ubuntu step by step or focus more on checking the phone’s USB mode settings first?

Here’s how you can set your OPPO Reno 5G to File Transfer (MTP) mode so Ubuntu can see your files:

📱 Steps on your OPPO Reno 5G

  1. Connect the phone
    Plug in your USB‑C cable to the phone and the USB port on your PC.

  2. Unlock the phone
    Make sure the screen is unlocked — otherwise USB options may not appear.

  3. Open the notification shade
    Swipe down from the top of the screen. You should see a notification like “Charging this device via USB” or “USB for charging”.

  4. Tap the USB notification
    This opens the USB preferences menu.

  5. Select “File Transfer” (MTP)
    You’ll see options such as:

    • Charging only
    • File Transfer / Android Auto
    • Photo Transfer (PTP)
    • MIDI

    Choose File Transfer / Android Auto. This enables MTP mode.

  6. Confirm connection
    Once selected, Ubuntu should detect the phone. In Nautilus, your OPPO Reno should appear in the sidebar as a device. Clicking it should show your internal storage and SD card (if present).

📝 Notes

  • If you don’t see the USB options, try another cable — some only support charging.
  • On some OPPO phones, the wording may be slightly different (e.g., “Transfer files” instead of “File Transfer”).
  • You may need to enable Developer Options → USB debugging if Ubuntu still doesn’t recognize the device, though usually MTP alone is enough.

Would you like me to also walk you through installing the MTP support packages on Ubuntu so you’re covered on both the phone and PC sides?

Copilot , could you please help me to install the MTP support packages for my                  PC/DESKTOP which is running UBUNTU 25 so that it can detect my OPPO Reno 5G smartphone ? THANKS.

Perfect — let’s get your Ubuntu 25 system ready to talk to your OPPO Reno 5G. You’ll need to install the MTP (Media Transfer Protocol) support packages. Here’s the step‑by‑step:

🛠️ Install MTP support on Ubuntu 25

  1. Update your package list
    Open a Terminal and run:

    sudo apt update

  2. Install the required packages
    These packages allow Nautilus (your file manager) to mount Android devices:

    sudo apt install mtp-tools gvfs-backends gvfs-fuse jmtpfs
    • mtp-tools → basic MTP utilities
    • gvfs-backends → lets GNOME/Nautilus access MTP devices
    • gvfs-fuse → mounts the phone’s storage into the filesystem
    • jmtpfs → optional, but useful if Nautilus doesn’t detect the phone

  3. Reconnect your phone

    • Unplug and replug the USB cable.
    • On your OPPO Reno, set USB mode to File Transfer (MTP).

  4. Check detection
    Run:

    lsusb

    If you see your OPPO device listed, Ubuntu recognizes it.

  5. Access via Nautilus
    Open Nautilus → look in the sidebar for your OPPO Reno. Clicking it should show Internal Storage and SD card (if present).

⚡ If it still doesn’t work

  • Try another USB cable (some only support charging).
  • Restart Nautilus: 
    nautilus -q
nautilus &
  • As a fallback, mount manually with jmtpfs: 
    mkdir ~/Phone
jmtpfs ~/Phone
    Then browse files in the ~/Phone folder.

Would you like me to also show you how to automatically mount your OPPO Reno every time you plug it in, so you don’t have to run commands manually?
