@VANHUSSEN
Did you try to restore from the command line in the container?

Yes, I have upload the backup file to `/var/www/discourse/public/backups/default/` directory on the new server.
Go to the /var/www/discourse/ directory on the new server.
> cd /var/www/discourse/
Install dependencies.
> sudo gem install thor
Go to Discourse **Admin dashboard** → **Settings** → **Backups** , tick on **allow restore**.
Next, run the following command to restore the site from backup.
> RAILS\_ENV=production script/discourse restore file-name-of-the-backup-file.tar.gz
Once the restore is finished, restart Discourse.
> sudo systemctl restart discourse discourse-sidekiq
And refresh the Discourse web page.
But on step:
> sudo gem install thor
I got the error. Why?

Hi @VANHUSSEN
From what little error messages you have posted, it looks like you have an issue with the version of Ruby you are running.
That is, at least, what your error message posted in your first post indicates.
Have to tried to rebuild your container and then run the restore process?

I have try this command:
Remove `ruby2.5-dev` .
> sudo apt remove ruby2.5-dev
Install `ruby2.6-dev` from a PPA.
> sudo apt install software-properties-common
> sudo apt-add-repository ppa:brightbox/ruby-ng
> sudo apt install ruby2.6-dev
But still get the error. Please help

Hi @VANHUSSEN
Perhaps it will be better if you simply rebuild the default, supported container versus using.
```plaintext
./launcher rebuild app
```
Assuming of course, your Discourse container is specified in `app.yml`

I kindly suggest you install with Docker if you are running a production Discourse application and requesting support on #Support .
If you are a developer and the installation is not production, that is another story 🙂 and you might consider posting over at #Development

If this isn’t a development install then docker is mandatory.
You need to be following the [standard install guide](https://github.com/discourse/discourse/blob/master/docs/INSTALL-cloud.md) for us to be able to offer any support.
