Show configuration when connection fails
When a backup fails - especially after the first try - this is usually due to a misconfiguration, e. g. a typo in the network address.
Currently, when a backup fails after the first try after using the wizard that helps you creating your first backup, the error message is shown, but after that, Deja Dup pretends like you now successfully configured your backup target. This leaves the user a little bit clueless, having to figure out where to change the setting in order to correct it and try again.
I suggest two things:
- Going back to the last step of the wizard after showing the error message when the connection to the backup target fails when the backup has been initiated by the "create first backup" wizard
- Always offer an easy way to open the configuration after the connection fails - e. g. a button "Reconfigure backup target" under the error message - because even if it's not your first backup, you might be able to fix it by changing the configuration (e. g. because the IP address changed, etc.)
