Traceback (most recent call last):
  File "ossync.py", line 27, in <module>
    from sync_thread import SyncThread
  File "/opt/ossync/sync_thread.py", line 56
    file_size =  os.path.getsize(filename)
                                         ^
IndentationError: unindent does not match any outer indentation level

how to solve it ?

相同的问题，解决方法：
文件用notepad++之类的编辑器打开，显示所有符号，56开始的几行缩进全部用tab制表符重写，之前错误的是因为使用了空格缩进。
