Problem importing data from a previous ghost blog



I had a blog running 0.11 and I am trying to migrate to 1.22.8. So as told in doc, I started by exporting my old blog, install a brand new with Cli, and then import back my data… but I got an error “Import failed due to an unknown error. Check the Web Inspector console and network tabs for errors.”

What is the web inspector console ? Is there somewhere I could get a log or something ?

Previously I was running sqlite3, but as I haven’t manage to install it with CLI, I went to mariaDB, could this be the problem ? Or do I have to recreate all previous user before importing ? Or is there another way to import ? I run ghost on a raspberry pi 2.
