2.4.0.beta8 update gave me the white page of death

I updated my Discourse at gradientdescent.co the same way I always do. There was an error during the 2.4.0.beta8 update.

Was this via /admin/upgrade or ssh? You don’t tell us which upgrade route you always use.

@ravenzachary

cd /var/discourse
git pull
./launcher rebuild app

Did you attempt this prior to reverting to b7, restoring a backup and using admin/upgrade? It’s all that should have been necessary here:

After updating Docker with one-click update, no Versions are showing

I just fixed the root cause that made that screen go white. We had an upgrade to our docker manager plugin which was not compatible with older versions of discourse, I added some code to restore compatibility. Unfortunately once that screen goes white your only recourse is: cd /var/discourse ./launcher rebuild app
