Why does pip3 want to create a kdewallet after installing/updating packages on Ubuntu 20.04?

I recently updated my system from Ubuntu 18.04 to 20.04. Afterwards I tried to update all of my pip3 packages using the shell command mentioned here (I changed "pip" to "pip3").

After it updated a couple of packages, this prompt came up: KDE Wallet Service

Since I never saw it while updating/installing a package, I cancelled it which resulted in an instant reopening of the same prompt and the terminal showed following warning:

WARNING: Keyring is skipped due to an exception: Failed to unlock the keyring!

I pressed CTRL+C after the same happend with the next package it tried to install. Ever since when I try to install a package the same happens.

Example:

pip3 install numpy
WARNING: Keyring is skipped due to an exception: Failed to unlock the keyring!
WARNING: Keyring is skipped due to an exception: Failed to unlock the keyring!
Collecting numpy
  WARNING: Keyring is skipped due to an exception: Failed to unlock the keyring!
  Using cached numpy-1.19.2-cp38-cp38-manylinux2010_x86_64.whl (14.5 MB)
Installing collected packages: numpy
  WARNING: The scripts f2py, f2py3 and f2py3.8 are installed in '/home/gesuchter/.local/bin' which is not on PATH.
  Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
Successfully installed numpy-1.19.2

I already tried to fix my issue with reinstalling python3-pip.

Here are hopefully some helpful information:

pip3 --version
pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)

ls ~/.local/share/keyrings
default  login.keyring  user.keystore

find ~/.config/kwalletrc
find: ‘/home/gesuchter/.config/kwalletrc’: No such file or directory
Solution

  • This solved it for me:

    python3 -m keyring --disable

    Running it adds:

    [backend]
default-keyring=keyring.backends.null.Keyring

    to the file ~/.config/python_keyring/keyringrc.cfg.

    Presumably PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring mentioned at https://stackoverflow.com/a/68504137/895245 offers an environment variable way to achieve the same result.

    Without this, it would show the annoying KDE keyring popup every time I try to install a package:

    Google, index this:

    The KDE Wallet System

    The application '/usr/lib/python3/dist-packages/pip/__main__.py' has requested to create a new wallet named 'kdewallet'. This is used to store sensitive data in a secure fashion. Please choose the new wallet's type below or click cancel to deny the application's request.

    • Classic, blowfish encrypted file
    • Use GPG encryption, for better protection

    TODO: poetry install from Poetry 1.8.2 is still opening up the popup several times. How to fix that one?

    Tested on Ubuntu 21.04, Python 3.9.5, pip3 20.3.4, keyring==22.2.0.
