Deltachat-desktop: Import backup not working

[ralphtheninja]

• export backup from android (old app)
• login on desktop
• import backup
• Cannot import backups to accounts in use. error in console

How is importing a backup supposed to work? Since you need to be logged in in order to select Import Backup... how can this have worked ever?

Managed to get it work, but I had to manually close desktop, enter the correct folder and rename the .bak file to db.sqlite. Something must have changed, either we have broken something in desktop or core is doing things a bit differently.

@r10s Are we doing something wrong from desktop or is this a bug in core?

Nevermind, it seems that this error is by design:

    if (dc_is_configured(context)) {
        dc_log_error(context, 0, "Cannot import backups to accounts in use.");
        goto cleanup;
        }

So this means this has never worked. This is more than just a bug. We have to rethink how an import should be made. At the moment you have to be logged in in order to even do the import, but being logged in (configured) means you can't do it...

Just checked android-ii and it has the import functionality on the first screen, so it makes sense to have this in desktop as well.

I would really like if the rule to prevent loading a backup file whenever I will do would be disabled. Currently it is blocking me from using desktop (I have 2 mobile devices which I try to have in sync and without an import I would destroy my keys !)
In mobile ui the import is offered, but fails (on my tablet) :-(
And later on the import backup option is not any longer offered (in mobile).
Maybe there are dummies who will destroy there database by importing an old backup unwanted (after selecting it, entering the key and accepting a question ...), but for experienced users it is a nightmare that the import is blocked (either by that message in desktop or the missing option in mobile ..)

I solved it moving DeltaChat.bak to /home/user/.config/DeltaChat/*/db.sqlite, but you need implement the import backup option to the first screen when user is logged out to work fine
