How to Fix the “Transport Endpoint is Not Connected” Error [5 Best Ways]

The “Transport Endpoint is Not Connected” message is a file system error that prevents you from accessing files and can cause system instability or unexpected crashes. This might happen due to sudden system shutdown, power loss, file system corruption, Kernel module issue, or hardware malfunction. To resolve this error, try the five effective solutions and four helpful prevention tips outlined in this article.

How to Fix the “Transport Endpoint is Not Connected” Error

To fix the “Transport Endpoint is Not Connected” error on Ubuntu, try unmounting and remounting the file system, checking for file system errors, restarting the system, updating packages, or checking for hardware issues. Let’s have a closer look at each of these five methods here:

1. Unmount and Remount the File System

The first solution is to unmount and remount the file system. This method works if a temporary disconnection between the file system and the mount point causes the error. Here’s how to do it:

1. Launch the Terminal and execute the command below:

lsblk

2. Now, note down the device node or transport endpoint that you want to disconnect.

3. Enter the following command to unmount the file system:

sudo umount -l /path/to/file-system

Replace /path/to/file-system with the actual path to your file system.

4. Once the file system is unmounted, execute the following command to check if the device is unmounted:

lsblk

5. You’ll see the following output:

6. Run the following command to remount it:

sudo mount -a

7. Now, you’ll see the following output:

2. Check and Repair File System Errors

If file system errors cause the error, you can try to fix them using the fsck command. This command checks and repairs file system errors. Here’s how to do it:

1. Run the following command to check only the mounted devices on your Linux machine:

df -h

2. Now, unmount it with the command below to avoid potential loss during the error-checking process:

sudo umount /dev/sdb1

3. Enter the following command to check the file system:

sudo fsck /dev/sdb1

4. This command will check for file system errors. It will display a list of errors, if any, and prompt you to confirm whether you want to repair them. You can type 1 for the first option or 2 for the second option. If you choose to repair the errors, it will attempt to fix them.

5. Once fsck has completed, you can remount the file system using the following command:

sudo mount /dev/sdb1

6. If this doesn’t work, you can simply reconnect your file system and check whether the error is resolved.

3. Restart the System

Simply restarting the system can sometimes fix the Transport Endpoint filesystem error on Ubuntu. It basically refreshes the system and resolves simple conflicts on its own. You can do this by following either of the steps below:

1. Enter the following command in the Terminal app or command prompt:

sudo reboot

2. Alternatively, you can click the Restart option located within the dropdown menu at the top-right corner.

3. Wait for the system to restart and check if the error is resolved.

4. Update and Upgrade Packages

If the error is caused by outdated packages, updating and upgrading them can fix the Transport Endpoint filesystem error. To do this, follow the steps below:

1. In the Terminal app, enter the following command to update and upgrade the package list:

sudo apt-get update && sudo apt-get upgrade

2. Wait for the upgrade process to complete.

3. If there are any updates to install, it will prompt and ask you to type either y or n. Here, you have to type y and press Enter.

4. Once done, check whether the endpoint error for the file system is resolved or not.

5. Check and Repair Hardware Issues

If the “Transport Endpoint is Not Connected” error persists after trying the above solutions, it might be caused by hardware issues. You can check for errors using the dmesg command. Follow these steps to use this command in the Linux command prompt:

1. In the Terminal app, execute the following command:

sudo dmesg | grep sdb1

Replace sdb1 with the name of your hard disk.

2. This command will display messages related to the hard disk in the kernel ring buffer.

3. If you do not see your file system here, it means that your system has some hardware component problem. This can happen due to a damaged hard drive, malfunctioning motherboard, or faulty cables. In these cases, you’ll have to consult the manufacturer’s documentation or support resources for guidance on how to fix the hardware component problem. Or you might even have to obtain a replacement component if necessary.
