Comment 9 for bug 2002949

Thank you for your trial.
Apologies, I forgot that I also installed the setproctitle python module,
as recommended by the WARNING message.
Here is the updated bug reproduction procedure.

[Test Case]
1. Install the package owning the file samba-tool
$ sudo apt install samba-common-bin

2. Install the setproctitle python module
$ sudo apt install python3-setproctitle

3. Run the following command
$ samba-tool user password --username=Michal --password='123&!(' --newpassword=1234bdt7q6q7wq

4. If you cannot reproduce the issue, install the following versions of above packages,
   and retry 3.
