App does not start after TimeMachine restore

[hoegertn]

When launching Leapp on a new MacMini M1 I get the following error.

Any hints?

Desktop (please complete the following information):

• OS: macOS BigSur on Apple Silicon
• Leapp Version: 0.4.5

This problem is not related to the M1 silicon, this is caused because the encryption of the configuration file on Leapp is based on the Machine ID.

By changing your Mac and using Time Machine, the App is unable to decrypt the config file.

To solve it, delete the file under ~/.Leapp and the app will work.

Sorry for the inconvenience

Thanks, it worked. Maybe an error message would be great.

Does that mean the config cannot be restored from a backup?

[andreacavagna01]

exactly, for security concern of someone trying to steal the configuration encrypted file, this file can only be decrypted with the machine ID of the first system in which Leapp is installed

[hoegertn]

I think this needs to be made clear with a warning sign. People might rely on backups made by TM to store their credentials.

Good point, absolutely a crash of the App is not the best idea, I'll add it in the next release

We're going to add a warning statement in the security section of the docs
