Change password error

[R D]

Hi all, 

when i try to change the password i get this error:

# stack set password
current system password:
new system password:
retype new system password:
  File "/opt/stack/bin/stack", line 155, in run_command
    rc = command.runWrapper(name, args[i:])
  File "/opt/stack/lib/python3.6/site-packages/stack/commands/__init__.py", line 2254, in runWrapper
    rc = self.run(self._params, self._args)
  File "/opt/stack/lib/python3.6/site-packages/stack/commands/set/password/__init__.py", line 54, in run
    self.runPlugins( [ old_password, new_password ] )
  File "/opt/stack/lib/python3.6/site-packages/stack/commands/__init__.py", line 1748, in runPlugins
    retval = plugin.run(args)
  File "/opt/stack/lib/python3.6/site-packages/stack/commands/set/password/plugin_unix.py", line 38, in run
    o, e = p.communicate('root:%s' % new_password)

    stdout, stderr = self._communicate(input, endtime, timeout)
  File "/opt/stack/lib/python3.6/subprocess.py", line 1481, in _communicate
    input_view = memoryview(self._input)
stack.commands.set.password: TypeError -- memoryview: a bytes-like object is required, not 'str'

Any idea?

What version of Stacki? This sounds like a missing decode() left over from the move to python3.

Hi R D,

@Mason this is actually in head of tree!

Sorry, I meant to reply to this yesterday.  We had a bit of a firedrill here in the office.

@R D, Mason is exactly right.  You can fix this yourself quite trivially, depending on how comfortable you are editing Python files.

What you need to do is open up

/opt/stack/lib/python3.6/site-packages/stack/commands/set/password/plugin_unix.py

And in the "subprocess.Popen()" call add an encoding parameter.

Basically, find the line in that file that looks like this (line 34 or so):

        p = subprocess.Popen(['/usr/sbin/chpasswd'],

and make it look like this.

        p = subprocess.Popen(['/usr/sbin/chpasswd'], encoding='utf-8',

Be sure the leading whitespace is still tabs, and don't forget the trailing comma.

I'll make the change in our codebase today and it will be in the next release of Stacki after rc7.

Bill
