How to access hassio files with SD card reader

Bad Config file prevented hassio from loading, ssh not working.
Tried to access the SD card with a Unix desktop and I don’t have permission to edit files. How do I remove those restrictions so I don’t have to start from scratch again.

Did you figure this out? I’m having the same issue.

Did you guys work this out? I have the exact same problem.
Of course, I can reinstall Hassio via Etcher but then I loose my config :frowning:
