Everything worked fine until today. I Upgrade the docker via the admin page, after it finished, the forum loads fine. I went to upgrade the discourse version but I then get to a page that tell me this:
<html><head></head><body> <h2>You are running an old version of the Discourse image.</h2> <p> Upgrades via the web UI are disabled until you run the latest image. </p> <p> To do so log in to your server using SSH and run: </p> <pre> cd /var/discourse git pull ./launcher rebuild app </pre>
I never had this page before. I logged in to the server via SSH and try to run those commands and I get:
Error: Docker version 1.11.2 not supported, please upgrade to at least 17.03.1, or recommended 17.06.2.
What to do? Thanks.
