During upgrade, I did cd /var/discourse; git pull; ./launcher rebuild app. I get “Upgrade Complete” and “UPGRADE OF POSTGRES COMPLETE”. The latter says to “rebuild again”, though it seems to make no difference. Despite upgrade being complete, I can’t start the app. Doing ./launcher start app give…

What is Your docker version? Did You try solutions suggested in this FAQ? [图片] PostgreSQL 12 update announcements warning WARNING! If your database is very large, you will need a lot of extra disk space (2x database size) and should be very careful with this upgrade! …

Thanks! Docker version 17.12.0-ce I am in a space-constrained environment (I’m constantly being asked attempt to clean up images), so that sounds like a plausible reason for this failure. Will try steps listed and report back.

Your discourse docker version is too old. I’d suggest updating that before proceeding.

Not sure how to do that without the web interface (or curl to the API), given that it’s down. But will look into it. I’m just going to upgrade my droplet disk size first and see if that helps. (unless you meant that my docker version is old?)

Ohh. I’m sorry. I meant to say docker is too old. Try upgrading that first. Extremely sorry for the typo and confusion.

No worries, I figured that’s what you meant, since you asked for docker version. I’m also on 14.04, so I’m going to upgrade that first, to 16.04. Thanks again for the input. Will post back any updates.

Working hard just to stand still… story of my life! Software moves too fast for me! :stuck_out_tongue_closed_eyes:

I wish you all the best with this new adventure of software upgrades. :confetti_ball:

[图片] AdrianoFerrari: I’m also on 14.04, so I’m going to upgrade that first, to 16.04. If that is a VPS it isn’t necessary to upgrade the current server. Spinnning a new one running 20.04 and moving your site to that new server is way faster and easier.
