Hi Coin-coin,
Could you be more specific about this? What does “crashes” mean here exactly?
To start the Discourse app on Ubuntu, there is a CLI tool, “/discourse/bin/ember-cli -u”. This will allow you to access the Discourse interface using http://localhost:4200. When I use Admin → Backup → Restore option, there is no error on the screen but there is a spinner on the screen, but the CLI windows closed.
Is there any error message on the screen/browser?
There is no error message on the screen/browser.
Which logs did you look for (there are many)?
There is no error log when I checked Admin → Logs → Error log interface.
