The error message "umount target is busy" in Linux means that the filesystem or device you are trying to unmount is currently in use by some process, and cannot be unmounted until that process releases it.
To fix this, you will need to identify the process that is using the target and terminate it or release the resource it is using. You can use the `fuser` command to find out which process is using the target:
```
sudo fuser -m /mount/point
```
Replace "/mount/point" with the actual mount point of the filesystem or device you are trying to unmount. This will show you the process ID (PID) of the process that is using the target.
You can then use the `kill` command to terminate the process, or try to gracefully shut it down by sending a termination signal:
```
sudo kill -TERM <PID>
```
Replace "<PID>" with the actual process ID you obtained from the `fuser` command.
Once the process is terminated or the resource is released, you should be able to unmount the target without getting the "umount target is busy" error.
