sdcard not mounted Ubuntu 14.04 LTS Desktop

Recently, I found that SDCard was not able to mount on my Ubuntu 14.04 LTS Desktop. This last Saturday, I decided to end up this issue. And yes, after working on laptop for marathon 5 hours, finally it is fixed.

NOTE: Before going to start, highly recommend to take your data backup. And save it in safe drive.

Details Of Operating System/Android/Phone

1. Ubuntu 14.04 LTS (Before Upgrade)
2. Arch: x86_64
3. Android 4 and Android 5
4. HTC,Lava [Android Phones]

Roadmap For The Solution

1. Install all dependency packages {MTP and GVFS}: We will install mtp and gvfs related packages.
2. Ubuntu 14.04 LTS Upgrade: We will OS upgrade. My system was by default upgraded to Ubuntu 14.04.3 LTS (It may differ case to case)
3. Test and confirmation: Plugin Android Phone with the help of USB cable.

While troubleshooting, I got to know 2 requirements are very important, that is –

  • 1. MTP Packages

    In current generation Android (version 4+), USB device class MTP(Media Transfer Protocol) have been used. MTP allows media files to be transferred to portable device. To know more about MTP, best suggestion is to read in Wikipedia.

  • 2. GVFS Packages

    You should also know about GVFS. GVfs (abbreviation for GNOME Virtual file system). To view the contents of your Android device’s storage via MTP in your file manager, gvfs helps you. Read more about GVFS from Wikipedia.

Steps To Follow – sdcard not mounted on Ubuntu 14.04 LTS

During this troubleshooting, I have not edited or modified any files like udev rules and fuse.conf.

Step 1. Install mtp and gvfs packages

sudo apt-get update

sudo apt-get install gvfs gvfs-fuse gvfs-backends mtpfs jmtpfs libmtp-common mtp-tools libmtp-dev libmtp-runtime libmtp9

NOTE: To solve the given below error which I found while troubleshooting, we are installing libmtp9. The error was found when I connected the SDCard to my laptop via USB cable.

Device 0 (VID=XXXX and PID=XXXX) is UNKNOWN.
Please report this VID/PID and the device model to the libmtp development team

Step 2. Now we will upgrade Ubuntu 14.04 LTS to available latest stable version.

sudo apt-get upgrade

Please note that OS upgrade will take lots of time, depending upon your internet bandwidth.

Step 3. After OS is upgraded successfully , restart the system.
Command to restart the Ubuntu.

sudo init 6

Step 4. Hope the system is booted properly and ready to work. Now, attach the SDCard to laptop via USB cable. It should work now. Given below is screenshot from my laptop.

sdcard not mounted

In case if it is not mounted. Check your mobile settings for USB. The MTP option should be selected, just as we have selected in given below screenshot.

sdcard mtp

In case you are still getting mtp and gfvs packages related confusion or need more details. I have taken output from my laptop about what are the packages I have installed.
