I have installed android-sdk then sdkmanager both using sudo apt install ... command and the result for sdkmanager --version is as following:

25.2.0

But when I try sdkmanager --update I get:

Traceback (most recent call last):
  File "/usr/bin/sdkmanager", line 33, in <module>
    sys.exit(load_entry_point('sdkmanager==0.5.1', 'console_scripts', 'sdkmanager')())
  File "/usr/lib/python3/dist-packages/sdkmanager.py", line 1074, in main
    raise NotImplementedError('Command "--%s" not implemented' % command)
NotImplementedError: Command "--update" not implemented

Also similar results for other commands like --install. What is the problem?
