I upgraded from 16.04 to 18.04 and now when I visit the site, it says “ERR_CONNECTION_REFUSED”.
I thought it was maybe certbot, and tried renewing certs which gives the error
The apache plugin is not working; there may be problems with your existing configuration. The error was: NoInstallationError('Cannot find Apache executable apache2ctl')
I tried visiting via IP address and it also says “ERR_CONNECTION_REFUSED”
Your help would be appreciated.
