Describe the bug
Starting on Zorin Linux (Ubuntu 20.04 derivative), with new environment and get this error from the archiver_plugin.py file:

Since I'm trying to test the new PYDMAbsoluteGeometry widget, I've been experimenting with pyqt and qt versions, looking for something that works (internal widgets scale with window resize event) with the new feature in both designer and the pydm application.

Expected behavior
Widget scaling should work (it does not work now but it did work in designer before I started experimenting with the environment).

Steps to Reproduce

Create a custom conda environment: mamba env create --force -f ./environment.yml

# file: environment.yml
# create conda environment for developing pydm and adl2pydm

# hint: use mamba instead of conda, its solver is faster

# command:    mamba env create --force -f ./environment.yml

name: dev22

channels:
  - defaults
  - conda-forge

dependencies:
  - python =3
  - black
  - flake8
  - ipython
  - mamba
  - pip

  # This gets Qt 5.9.7
  - qt
  - pyqt5

  - pip:
    # - pyqt5 >=5.15
    # get Qt designer application
    # --- no success !
    # dead-ends
    # - pyqt5-tools
    # - pyqt5-plugins
    # - pyqt5designer
    # - qt5-applications
    # - pyqt5-sip

    # requirements.txt
    - numpy>=1.11.0
    - pyepics>=3.2.7
    - pyqtgraph>=0.12.0
    - qtpy
    - requests>=1.1.0
    - scipy>=0.12.0
    - six

    # dev-requirements.txt
    - codecov
    - pytest>=3.6
    - pytest-qt
    - pytest-cov
    - pytest-timeout

Then

conda activate dev22
cd slaclab/pydm
pip install -e .

Finally, test with this motorX.ui screen file:
motorxU.ui.txt

Possible Solution

This problem looks like a conflict created upstream and we may not need the krb5 feature that is missing. Others have encountered this problem and come to this conclusion.
