The upload page told me: Updates via the web UI are disabled until you run the latest image. To do so log in to your server using SSH and run: cd /var/discourse git pull ./launcher rebuild app The first time it ran for a while and then ended with the error. If I try again I get: ./launcher rebuild app x86_64 arch detected. ERROR: containers/app.yml does not exist or is not readable. Available configs ( data, mail-receiver, web_only ) The file does not exist: ls -al containers total 28 drwxr-xr-x 3 root root 4096 Jan 15 18:12 . drwxr-xr-x 12 root root 4096 Jun 19 17:34 .. -rw-r--r-- 1 root root 0 Jun 11 2023 .gitkeep -rw------- 1 root root 1175 Jun 27 2023 data.yml drwxr-xr-x 2 root root 4096 Jun 27 2023 delete -rw-r--r-- 1 root root 2306 Jan 15 18:12 mail-receiver.yml -rw------- 1 root root 6304 Jan 2 20:39 web_only.yml Running in a Digital Ocean droplet.

It looks like you have a two-container setup rather than the usual one container called app. For a two-container setup I believe you would need to run: ./launcher bootstrap web_only && ./launcher destroy web_only && ./launcher start web_only Though usually people with a two-container setup are aware of the difference. Is this the first time you’ve updated since you installed?

I’ve used the automatic update in the web UI but never got the message about ./launcher rebuild app before. @pfaffman did the installation.

Seems like that command worked, thanks.

Glad you got it figured out! You can also sign up for my rebuilds program and do it with a click from dashboard.literatecomputing.com. You can also join the free trial group and use the dashboard for free, though without my support (except when I give it for free here!)

Ah, yes. I think he has some instructions with some extra detail in - Managing a Two-Container Installation - Documentation - Literate Computing Support
