Error during upgrading from Beta 3.1.x to latest

Doing an upgrade approx. every 2 to 3 days the last updated succeeded.

Today’s update via the /admin/upgrade URL first failed.

Then I did the usual:

cd /var/discourse
sudo git pull
sudo ./launcher rebuild app

This also resulted in an error:

Scrolling more up, I see an entry:

PG::UniqueViolation: ERROR:  duplicate key value violates unique constraint "index_tags_on_name"
DETAIL:  Key (name)=(net) already exists.

I’m really clueless on how to fix/resolve.

My forum is now offline. I’ve ran sudo ./launcher rebuild app again. It failed, too.

Could someone please help me with some suggestions on how to resolve?

Please run ./launcher start app to reboot the old image. That may bring your forum back online.

Thanks a lot.

The container is now running again, still the error persists.

Most likely I have the same Issue as here:

I’ll not try to resolve it the same way as described there.

Update 1 - Solution

OK, it seems I was able to resolve with these steps:

  1. Edited the app.yaml and did:
  2. Rebuilt the image.
  3. Activated and started Data Explorer plugin and used this query to identify the duplicate tags.
  4. Used the regular admin GUI to identify the tags. Then renamed one tag to be unique again.
  5. Removed the pinned version again.
  6. Rebuilt Discourse sudo ./launcher rebuild app. This succeeded now.
  7. After starting Discourse, I went to the tags admin area and further worked on the duplicated (deleted one of the formerly duplicate tags after assigning the other tag).
