Hi, first-time Discourse user with not much tech knowledge.
I have installed Discourse on Lightsail Ubuntu 18.04.2 using the official instructions. Forum up and running no problem.
Now tried to install a plugin: Install Plugins in Discourse
./launcher rebuild app gives this error
“Your Docker installation is not using a supported storage driver. If we were to proceed you may have a broken install. aufs is the recommended storage driver, although zfs/btrfs/overlay and overlay2 may work as well. Other storage drivers are known to be problematic. You can tell what filesystem you are using by running “docker info” and looking at the ‘Storage Driver’ line. If you wish to continue anyway using your existing unsupported storage driver, read the source code of launcher and figure out how to bypass this check.”
Have searched for the same message in this forum and I am not clear exactly what to do from the replies.
Docker info on my set-up gives overlay2.
Not sure how Discourse can install ok, then the plugin install/rebuild not work.
Between installation and the plugin install/rebuild attempt, I have only updated Discourse and docker manager as per a notification, and performed apt-get update and apt-get upgrade.
Can someone clarify whether overlay2 can work? Or whether aufs is needed? What exactly are the instructions I need to follow to get the plugin install working?
