I tried to upgrade my recovery partition today and it failed with “No such device”/OS error 19.

I found this discussion on Reddit in which @mmstick suggested restarting, but with no explanation as to why that was needed or would work. It worked for me.

I’d like to know why it worked and why it was needed, mostly for two reasons: to generally understand the situation better and to imagine what I might have been able to do that didn’t require restarting.

Thanks.

    Did you check if the recovery partition was recognised and mounted? Maybe some voodoo made it fail to mount, but it worked after a reboot.

      Yes, it was. I checked by unmounting it, then running the upgrade command, which resulted in a clear error message about the partition not being mounted. I don’t remember the specific message, but I remember it was different than the one I got when it was mounted. This leads me to believe that the OS error 19 message is some kind of red herring.

      Thanks.
