• Linux on Lightsail instance is asking for a password and it's not working

  I'm trying to restart mariaDB on Ubuntu but it's not letting me.

  I enter:

  systemctl restart mariadb
  

  and get:

  ==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units ===
  
  Authentication is required to restart 'mariadb.service'.
  
  Authenticating as: Ubuntu (ubuntu)
  
  Password: 
  
  polkit-agent-helper-1: pam_authenticate failed: Authentication failure
  
  ==== AUTHENTICATION FAILED ===
  

  I have the same password for all functions so I do not understand why it is not working. What can I do?
• How to tag and store files, by metadata, in Python?

  I want to build a manual file tagging system like this. Given that a folder contains these files:

  data/
      budget.xls
      world_building_budget.txt
  a.txt
  b.exe
  hello_world.dat
  world_builder.spec
  

  I want to write a tagging system where executing

  py -3 tag_tool.py -filter=world -tag="World-Building Tool"

  will output

  These files were tagged with "World-Building Tool":
      data/world_building_budget.txt
      hello_world.dat
      world_builder.spec
  

  Another example. If I execute:

  py -3 tag_tool.py -filter="\.txt" -add_tag="Human Readable"

  It will output

  These files were tagged with "Human Readable":
      data/world_building_budget.txt
      a.txt
  

  I am not asking "Do my homework for me". I want to know what approach I can take to build something this? What data structure should I use? How should I tag contents in a directory?

• Getting mongo authorization errors with userAdminAnyDatabase role

  I am trying to get authorization working on a mongo database on a new Ubuntu machine. I have created an admin user with the role userAdminAnyDatabase:

  admin> show users
  [
    {
      _id: 'admin.mongoAdmin',
      userId: UUID("590a4465-625a-4fa0-af2e-0f2c75777ac5"),
      user: 'mongoAdmin',
      db: 'admin',
      roles: [ { role: 'userAdminAnyDatabase', db: 'admin' } ],
      mechanisms: [ 'SCRAM-SHA-1', 'SCRAM-SHA-256' ]
    }
  ]
  

  but I get authorization errors when I try to do anything:

  admin> use test
  switched to db test
  test> db.users.find({})
  MongoServerError: not authorized on test to execute command { find: "users", filter: {}, lsid: { id: UUID("f3cf2fbc-bbea-4ceb-83a1-b842b5047e74") }, $db: "test" }
  

  I know I am using the correct id/password, as when I try to run the mongo shell with a different password it fails to start with a password error.

  Ubuntu version is 20.04.4 (Focal); Mongo version is 5.0.8:

  % mongod --version
