Help! Upgrade led to complete fail

installation
1

Hi,

When running most recent upgrade (something 6 to 7), rake db:migrate failed because of a supposed duplicate username. As I’m not really comfortable with the Linux commandline, I then tried to enter the rails console in order to fix this but the console won’t load because it couldn’t connect to the database. I then googled and tried /etc/init.d/postgresql restart but that failed with:

[....] Restarting PostgreSQL 12 database server: main[....] 
Error: /usr/lib/postgresql/12/bin/pg_ctl /usr/lib/postgresql/12/bin/pg_ctl start -D /shared/postgres_data -l /var/log/postgresql/postgresql-12-main.log -s -o -c config_file="/etc/postgresql/12/main/postgresql.conf" exited with status 1: 2021-03-08 20:19:10.354 UTC [763] 
FATAL: database files are incompatible with server 2021-03-08 20:19:10.354 UTC [763] 
DETAIL: The data directory was initialized by PostgreSQL version 13, which is not compatible with this version 12.3 (Debian 12.3-1.pgdg100+1). p[FAIL: could not start server Examine the log output. ... failed!
 failed!

I then tried /etc/init.d/postgresql restart version 12.3, that didn’t give an error but also no other message. And it’s still impossible to log into psql (at least using sudo -u postgres psql discourse which I found on this forum).

Can anyone advise how to restore the server? And why did the latest upgrade cause such a huge error anyway? I used the 30-minute installation, everything is as standard as can be. I’m also ready to pay someone to fix this.

@pfaffman specializes in this kind of support, perhaps contact him.

Do you have the exact failure? you may need a bit of scrolling, but I am curious about

  1. The name of the migration that failed
  2. The statement that caused it to fail

There was a bug somewhere along the way that allowed usernames with different capitalization. And then it got fixed so that it doesn’t.

You might be able to crank up the old container and fix it with the ux.

But if you haven’t done a command line upgrade for a while, then there’s also a database upgrade,which further complicates things.

If it’s not much worse than that, I’ll fix it tomorrow morning pacific time Automatic Rebuilds when They Are Needed — Literate Computing, LLC

Is you want to pay more to get it done tonight, email Jay@literatecomputing.com soon and I might be able to at least get it back up.

Spinning up 3 Unicorn worker(s) that were stopped initially

I then ran the update via SSH, hoping that that would be more robust (in 2020 there were a few months when the web interface refused to update anything and I always had to go via SSH). When I typed the update command on the commandline, it downloaded a bunch of stuff and eventually told me to run the rebuild app command. When I did that, the same error occurred. I cannot attest whether the surrounding lines were the same and I didn’t copy them, but it definitely had this index_username_on_users issue in the middle of the database migrations.

TL;DR: If I interpret the output correctly, the problem occurred in the RenameEnglishLocale migration on the execute("UPDATE users SET locale = 'en' WHERE locale = 'en_US'") command.

I have seen this error before, it happens when there is an internal corruption in the users table.

Somehow you have a duplicate “user” record in the table, it snuck in during an earlier version or during an upgrade or during a rude shutdown. I still do not know exactly why it happens, but I have seen it happen.

You have 2 alternatives:

  1. If you are lucky ./launcher start app then rails c then DB.query('select * from users where username='Martina_S') then rename the last Martina_S to something like Martina_S1

  2. If you are not lucky you will not be able to start the app, then you are going to need to boot a data container and run the above from psql

Thank you for your quick replies! How do I boot a data container? I tried ./launcher start app and then rails c, but Rails won’t start because the database is not running. I tried /etc/init.d/postgresql restart but got the error you see in the initial post, something about the Postgresql version being incompatible (Debian LTS only supports 12.x, while the latest Discourse upgrade appears to have migrated my data to 13.0??). I’d be fine fixing this in SQL, I’m a Rails developer after all, but I have no idea how to fix what looks like a botched Postgresql update on a Linux commandline.

Look in the sample dir for an example data container

You just need to point it at the right location, then you should be able to enter the container and run psql

Yeah you are already upgraded to 13
