Comment 2 for bug 1958009

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Bug reporting is about finding & fixing problems thus preventing future users from hitting the same bug.

I suspect a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu. You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community-support/709

You appear to have listed boot messages; but have tagged your issue is with python3-defaults? I don't see the connection between what appear to be linux kernel messages and the python3-defaults. Clarification of what your python3 issue maybe required, so converting this to a question maybe helpful.
