Hey @sweetpotatoz

I have the same problem (probably), Parrot OS (Debian based) here. Maybe little bit different. I haven’t added /snap/bin to the PATH. But when I added my output not it’s showing this. So when I do export in new session:

export PATH=$PATH:/snap/bin

I can work with microk8s. $ microk8s (…)

My question is: Do you have in new sessions /snap/bin in your PATH? If not this is the problem.

I’ve faced the same error and figured out that python uses user defined site-packages:

$ /snap/microk8s/current/usr/bin/python3 -m site
sys.path = [
    '/home/user',
    '/snap/microk8s/current/usr/lib/python35.zip',
    '/snap/microk8s/current/usr/lib/python3.5',
    '/snap/microk8s/current/usr/lib/python3.5/plat-x86_64-linux-gnu',
    '/snap/microk8s/current/usr/lib/python3.5/lib-dynload',
    '/home/user/.local/lib/python3.5/site-packages',
    '/snap/microk8s/current/usr/lib/python3/dist-packages',
]
USER_BASE: '/home/user/.local' (exists)
USER_SITE: '/home/user/.local/lib/python3.5/site-packages' (exists)
ENABLE_USER_SITE: True

In my case PyYAML package in /home/user/.local/lib/python3.5/site-packages has version 3.11 and an output of python says the same:

$ /snap/microk8s/current/usr/bin/python3
Python 3.5.2 (default, Oct  8 2019, 13:06:37) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import yaml
>>> yaml.__version__
'3.11'

After deleting a directory /home/user/.local/lib/python3.5/site-packages (I have no python 3.5 anymore) I have next site-packages:

$ /snap/microk8s/current/usr/bin/python3 -m site
sys.path = [
    '/home/user',
    '/snap/microk8s/current/usr/lib/python35.zip',
    '/snap/microk8s/current/usr/lib/python3.5',
    '/snap/microk8s/current/usr/lib/python3.5/plat-x86_64-linux-gnu',
    '/snap/microk8s/current/usr/lib/python3.5/lib-dynload',
    '/snap/microk8s/current/usr/lib/python3/dist-packages',
]
USER_BASE: '/home/user/.local' (exists)
USER_SITE: '/home/user/.local/lib/python3.5/site-packages' (doesn't exist)
ENABLE_USER_SITE: True

After that microk8s starts to work:

$ microk8s status
microk8s is running

Is it possible to disable ENABLE_USER_SITE for snap microk8s (environment variable PYTHONNOUSERSITE=false)?

thanks @realmfoo snap has its own python 😕 i went in here /home/user/.local/lib/python3.5/site-packages and delete rm -rf yaml and the yaml error has gone.
