Chrome OS and Crostini: error restore tini file

[COPINE Patrick]

Hello,

After changing my Acer CB5 312T Chromebook to an Acer 513 Chromebook, I am trying to restore the Linux part of the CB5 to the 513. When the restore is complete, I have the error below. Do you have any idea of ​​the reason for this and a workaround for restoration?

Thank you.
