[Neon] Tracebacks in pkg.installed

[max-arnold]

The state succeeds, but there are a couple of tracebacks in the debug log triggered by the loader (this probably means that these unrelated modules should be fixed):

sudo salt-call state.single pkg.installed nginx -l debug

im replicating the boto and docker tracebacks but not the psutil one and i ensured i did not have it installed. When i looked at the code it looks like its intentionally not catching the importerror because of this comment https://github.com/saltstack/salt/blame/master/salt/utils/psutil_compat.py#L19 but i did not think we required psutil. Can you confirm @s0undt3ch that we do not indeed require psutil? if so we can just catch that importerror exception

[s0undt3ch]

psutils is not a hard requirement. I guess we started having this when we started supporting __utils__, and in this context, we start catching the exception.

[max-arnold]

I wonder what might be different in your setup in regard to psutil. I just tried to reproduce it on a clean Vagrant box (bento/ubuntu-18.04) and it happens reliably. Below is the bootstrap command I used:

bootstrap-salt.sh -P -x python3 -f -g https://github.com/saltstack/salt.git -F -c /tmp git master

The swarm module traceback looks to be fixed in https://github.com/saltstack/salt/pull/57489.

I've opened #58554 for the boto3_elasticsearch traceback.

@max-arnold I can still reproduce the psutil utils problem using your instructions in https://github.com/saltstack/salt/issues/55848#issuecomment-574546524 with the latest master (931580afdc).

[lnxslck]

I have this issue too. Is there a fix for this?
