Did you configure mutual trust with the root user? I see your user is tidb, but the key points to the root directory.

Do you want to deploy using the tidb user or the root user? If you want to use root, replace “user” in the command with “root”. If you want to use tidb, configure mutual trust for tidb, and then point the command key to the mutual trust directory of tidb.

I encountered a situation where mutual trust was configured but not recognized. Later, I upgraded tiup and tiup cluster, and it was resolved.

I remember TIUP will automatically configure SSH mutual trust, right?
