NOTE: Original post updated 11/25/21 PM EST with new information Notified of critical security updates to my Discourse installation I attempted to update my installation using the Web UI (/admin/upgrade) as I have done in the past. There were two pieces of software that needed to be upgraded—Docker Manager and Discourse. The Docker Manager had to be upgraded first (the Discourse upgrade button was disabled). I started the Docker Manager upgrade using the Web UI and it completed successfully. I then started the Discourse upgrade but it failed midway through. When I refreshed the Web UI I saw the following message: [image] So, following the onscreen instructions, I SSH’d into the server, did a git pull and then ran sudo ./launcher rebuild app from the command line. The process finished but failed with a FAILED TO BOOTSTRAP error message. Here is the output of two runs of sudo ./launcher rebuild app at different times: launcher-rebuild-app-output-0.txt - Lines 88-95 launcher-rebuild-app-output-1.txt - Lines 100-107 The line numbers after each file are where the only ERRORs appear. Both appear to be database and role related (the difference between both ranges is because the second attempted a git pull from the discourse/base repository). 2021-11-25 21:21:38.451 UTC [64] postgres@postgres ERROR: database "discourse" already exists 2021-11-25 21:21:38.451 UTC [64] postgres@postgres STATEMENT: CREATE DATABASE discourse; createdb: error: database creation failed: ERROR: database "discourse" already exists I, [2021-11-25T21:21:38.454429 #1] INFO -- : I, [2021-11-25T21:21:38.454908 #1] INFO -- : > su postgres -c 'psql discourse -c "create user discourse;"' || true 2021-11-25 21:21:38.531 UTC [68] postgres@discourse ERROR: role "discourse" already exists 2021-11-25 21:21:38.531 UTC [68] postgres@discourse STATEMENT: create user discourse; ERROR: role "discourse" already exists This appears to dovetail with the FAILED error message displayed at the bottom of each Launcher Rebuild attempt.

Note: These ERRORS are not the root problem. See “Solution” below. Some people below have said that there is an issue with redis that is preventing a successful rebuild. I ran `sudo ./discourse-doctor at various times during the day. Here is the output from two of the runs: discourse-doctor-output-0.txt - could not find ‘app’ container running; attempted rebuild but failed to restart the container discourse-doctor-output-1.txt - ‘app’ started manually with sudo usr/bin/docker start app before running discourse-doctor I verified that my Docker installation was running correctly by running sudo docker run -it --rm hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world 2db29710123e: Pull complete Digest: sha256:cc15c5b292d8525effc0f89cb299f1804f3a725c8d05e158653a563f15e4f685 Status: Downloaded newer image for hello-world:latest Hello from Docker! This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (amd64) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. I ran sudo ./launcher cleanup to make sure I had enough disk space. WARNING! This will remove all images without at least one container associated to them. Are you sure you want to continue?

The Docker app container is running after a reboot. $ sudo docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 6449ec0061a0 local_discourse/app "/sbin/boot" 7 weeks ago Up 25 seconds 0.0.0.0:80->80/tcp, :::80->80/tcp, 0.0.0.0:443->443/tcp, :::443->443/tcp app But when I go to the site I get a “502 Bad Gateway” error. [image] When I stop the app container and go to the site I get a “Unable To Connect” error (which seems right since the container isn’t running). [image] But this puzzles me since I don’t have Nginx installed on this server. I can see in the Rebuild output where the process is copying Nginx files from one location to another but I cannot find the corresponding directories or files, specifically nginx.conf on my server anywhere. Ubuntu, Docker, and Discourse are not my primary skills but I am assuming that these files are being copied “within” the Docker app container. Thanks in advance; appreciate any additional help or direction with this issue, which seems to surface from time to time during Discourse upgrades. UPDATE: It turns out my assumption regarding the Docker app container having its own internal filesystem is correct. You can create a snapshot of the container filesystem and explore this filesystem using bash. # create image (snapshot) from container filesystem $ sudo docker commit mysnapshot $ sudo docker run -t -i mysnapshot /bin/bash In the app filesystem there is an nginx directory that contains a Discourse configuration file. root@f91826d986eb:/etc/nginx/conf.d# ls -l total 12 -rw-r--r-- 1 root root 10568 Oct 3 21:33 discourse.conf

Following Michael’s advice in the above post, I commented out a plug-in in the app.yml file that was from an initial attempt at SSO authentication using the VK plug-in (we never went with this implementation but obviously forgot to remove the plug-in from the app.yml file). ## Plugins go here ## see https://meta.discourse.org/t/19157 for details hooks: after_code: - exec: cd: $home/plugins cmd: - git clone https://github.com/discourse/docker_manager.git ## - git clone https://github.com/discourse/discourse-vk-auth.git After commenting out the line above I ran sudo ./launcher rebuild app again. After the rebuild the forum site appears to be up and running (testing now). Thanks again for everyone who took the time to review my posts and comment. Your help was very much appreciated (what better way to spend a the Thanksgiving holiday here in US :wink:). Stay safe.

How about restart? From here [image] The launcher command in the /var/discourse folder are not self-explaining Self-hosting I had to change and reload the configuration a couple of times for troubleshooting Siteground mail service. There are multiple bits of advice on how to do it most quickly. Summarizing all of them leaves confusion. So, could you tell me the differences between the commands listed below in more detail? The information in install guide and posts in this forum are somehow inconsistent. It isn’t fully clear what e.g. is the difference between initializing and building a container. There should be…

This update requires the docker to be restarted. So, yes your discourse is gonna be offline while you run ‘./launcher rebuild app’ in then command line. All will be 100% once the rebuild is completed.

@IAmGav Docker appears to be running. [image] @rmccown ZSm8WzJ7gLigPd08D4tiwt.png) I will try some of the other launcher commands to see if I can get things up and running.

@IAmGav Ran ./discourse-doctor and it also confirmed that Docker container is running. ==================== DOCKER INFO ==================== DOCKER VERSION: Docker version 20.10.11, build dea9396 DOCKER PROCESSES (docker ps -a) CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 6449ec0061a0 local_discourse/app "/sbin/boot" 7 weeks ago Up About an hour 0.0.0.0:80->80/tcp, :::80->80/tcp, 0.0.0.0:443->443/tcp, :::443->443/tcp app Discourse container app is running

@rmccown Tried both start and restart without luck. [image] Still get this at the URL. [image] Running sudo ./launcher rebuild app again fails with these messages (currently looking through the file for earlier error messages). [image]

When all else fails - have you tried unplugging it and plugging back in? :wink: Reboot the instance: reboot now Bring the instance up to latest: apt-get update and apt-get dist-upgrade Then run the Discourse upgrade.

@omarfilip That’s the first thing I tried :wink: I just tried a reboot again (no Ubuntu 18.04.6 components to upgrade from earlier upgrade). [image] Same results - 502 Bad Gateway error at URL. But thanks for the suggestion.

Also just found this from November 2020 - Upgrade ends with FAILED TO BOOTSTRAP. But I have to admit I don’t know exactly what it means to “follow our default release channel.” I assume that upgrading via the Web UI is the “default release channel.”

That would be “tests-passed.” If you have not modified this line in your app.yaml file, then you are on the default release channel: ## Which Git revision should this container use? (default: tests-passed) #version: tests-passed
