Error: Unable to write to temp_path ('/tmp')

[cavu]

I have a new install of Nagios Core 4.4.3 running on Ubuntu 18.04 lts , when i run the preflight check, I am getting the error Error: Unable to write to temp_path ('/tmp') - Permission denied.

I tried to sudo chmod 775 /tmp, but did not clear the issue. Any ideas how to fix error?

What is the output of these commands:

Code: Select all

ls -ld /tmp
mount | grep acl
