How do I enter YES??

[Profezor]

Trying to fix cache.

It asks to enter y.

 

How?

I believe it's a known issue, you'd need to run it manually, but note the warning, btrfs check --repair should only be run as a last resort, or it could makes thing worse, if the filesystem is unmountable some safe things you can try first here.

Thanks.

I reformatted and reinstalled from backup.

Back working now.

Thanks
