I run Discourse on Debian 11 with Docker as a single container. I tried to update it using ./launcher rebuild app It fails with this message I, [2023-01-04T20:53:09.920876 #1] INFO -- : > cd /var/www/discourse && su discourse -c 'bundle exec rake db:migrate' rake aborted! I do not find a way to get it up and running again. Any ideas?

I was able to set the version to 2.9.0.beta2 (commit id: 88a8584348ed93a28286839bfc1c32b06bd50b3f) by setting the commit id as “version” in app.yml. This time the upgrade worked. After that I was able to upgrade to 3.0.0.beta16. Thanks to all.

I see that the owner is wrong drwxr-xr-x 15 sshd netdev 4096 Jan 4 21:43 . drwxr-xr-x 3 root root 4096 Jan 3 2018 .. drwxr-xr-x 3 1000 www-data 4096 Jan 3 2018 backups drwxr-xr-x 8 sshd netdev 4096 Feb 2 2021 letsencrypt drwxr-xr-x 4 sshd netdev 4096 Jan 3 2018 log drwxr-xr-x 2 systemd-timesync systemd-resolve 4096 Jan 3 2018 postgres_backup drwx------ 19 systemd-timesync systemd-resolve 4096 Jan 4 21:53 postgres_data drwx------ 19 sshd netdev 4096 Jan 4 20:49 postgres_data_new drwxrwsr-x 6 systemd-timesync systemd-resolve 4096 Jan 4 21:53 postgres_run drwxr-xr-x 2 systemd-resolve kvm 4096 Jan 4 21:53 redis_data drwxr-xr-x 2 sshd netdev 4096 Jan 22 2021 ssl drwxr-xr-x 2 sshd netdev 4096 Jan 21 2021 ssl_old drwxr-xr-x 4 sshd netdev 4096 Jan 3 2018 state drwxr-xr-x 4 1000 www-data 4096 Jan 4 21:28 tmp drwxr-xr-x 4 1000 www-data 4096 Jan 5 2018 uploads I start the container using ./launcher start app. Than enter the container: ./launcher enter app. I reset the ownership chown -R postgres:postgres /shared/ Afterwards it’s corrected. But when I rebuild the app again the owner is wrong again…

This isn’t the error, it’s going to be higher up, we’re going to need to see more of the log.

If you have changed owners of the files inside the shared folder you will break the install. One option is reinstalling and restoring a backup, while the other is manually fixing those owners.

@Falco: thank you! I changed the owners after the upgrade failed. I found the chown hint somewhere in a post. How can I create a backup in the current state? How can I fix the owners manually? Thanks again!

inside the container I tried discourse backup. It reports that Redis is not running. In the “current” Redis log I found the following lines at the end… 10316:M 05 Jan 2023 08:05:27.314 # Server initialized 10316:M 05 Jan 2023 08:05:27.314 # WARNING overcommit_memory is set to 0!

I fixed the permissions like this (inside the container): [grafik] Afterwards I restarted the container with ./launcher restart app Now I can access Discourse. But it’s the old version 2.8.3 that I tried to upgrade to 3.0.0.beta16 yesterday. I’m not sure how to proceed to upgrade Discourse.

I think my problem is related to this thread: Problem upgrading multi-site/multi-containers Discourse instance - #5 by jtraulle I remember that I had upgrade problems before but never investigated them.
