Sometimes stray daemons left over from previously running processes will cause strange bugs or errors when upgrading to a new version.

Make sure all daemons and chia processes are killed before installing or upgrading.

This is normally done by executing chia stop -d all from the upgrade example above.

But it does not hurt to double check using ps -Af | grep chia to make sure there are no chia processes left running.

You may have to manually kill the chia daemon if an install and chia start was performed without first running chia stop -d all.

If all else fails, rebooting the machine and restarting the chia daemon/processes usually does the trick.
