Not able to Upload/download files from blob through Ubuntu VM command line

Hi,

I have written a code in java to upload/download files from blob storage using REST API. I have created the jar file including external libraries from win azure. It runs successfully when I run it through windows command prompt. I want to run the jar file on my Ubuntu VM and access my blob storage from there.

For some reason, I am getting problem while uploading/downloading files through VM.

Earlier I thought that there could be problem with the path that I am giving. But I have verified that the path that I am passing through console is correct. (/dev/shm/testfiles/filename.jpg)

I am able to access my storage but there is a problem while uploading/downloading files from blob.

I also tried giving the path in the code itself but it is not working. Here is the code for upload-

public static void MyUploadBlob(String containername, String containerSAS, CloudBlobClient blobClient, String[] fileList, int iter)
               throws URISyntaxException, StorageException, FileNotFoundException, IOException
          {
              String blobName = fileList[iter];  // contains file name to be uploaded in the blob
              String localFileName = "/dev/shm/testfiles/" + fileList[iter];  // Path and name of the local file.

              // Append the container name, blob name, and
              // shared access signature to the URI.
              URI uri = new URI(blobClient.getEndpoint().toString() + "/" +
                                containername + "/" +
                                blobName +"?" +
                                containerSAS);

              // Create a blob using the URI that contains the shared access signature.
              CloudBlockBlob sasBlob = new CloudBlockBlob(uri, blobClient);

              // Get a file reference to the local file.
              File fileReference = new File (localFileName);
              
              // Upload the file to the blob.
              sasBlob.upload(new FileInputStream(fileReference), fileReference.length());
              
          }

Any help will be greatly appreciated.

Thanks
