This suggests you are not running a standard install. Can you describe your exact setup?

4

Hmm, default install…
Also I set disable_emails=t and rebuilt
What can be different for such behavior?

5

Where was the backup created? If it was another system, you should upgrade it and then try the restore.

I still see this when the database versions don’t match, I think.

It’s on the same version, just after ./launcher rebuild app => create backup => restore.

7

And by “default install” you mean https://github.com/discourse/discourse/blob/master/docs/INSTALL-cloud.md?

DId you initiate the backup/restore from the command line or the web interface?

8

Yes, default instructions.

From web interface

9

You can try rebuilding again.

Why are you doing a backup and restore?

10

I tried (with rm -rf shared), but with no success.
I’m migrating from another forum system, so I do it step=>backup=>step=>backup (and if something fails => restore)

11

My guess is that the old system is not on the same version of postgres as the new system.

What does

./launcher enter app
psql --version

return on each system?

I’d rebuild the old system from the command line and then rebuild the new system from the command line.

Oh, and you might see what

./discourse-doctor

says about both systems. (I tihnk that discourse-doctor does not check for postgres version and that it should).

12

psql (PostgreSQL) 10.4 (Ubuntu 10.4-2.pgdg16.04+1)

13

And it is the exact same on BOTH systems?

14

What do you mean - on each system? I have only 1 system

15

Where are you doing this migration?

And this is inside a docker container?

16

On my machine, similar to this https://github.com/Haulmont/useresponse-to-discourse

17

I think, it’s not important, because I backuped fresh version of discourse and tried to restore. So I have fresh discourse and admin account (rake admin:create) and then backup=>restore ==> failure

18

Discourse version v2.1.0.beta2 +478

I’ve tried to install discourse on another computer (fresh discourse without modifications) and I have the same error. bug @sam
varsion:stable is ok

20

So you did a new install. And then immediately made a backup and tried to restore it?

21

Actually I have the same issue. I have created a backup and then reinstalled Discourse with the same Ansible script, and now I cannot import the backup.

It looks like I’ve been able to upload an older backup, but not the last one.

There may be a problem with the last Discourse version not creating a good backup file.
