The new software moved the keystore to the liked
command, and provided new option for using the OS keystore instead of in file. If you are operating on Linux, then it may not be an issue as the OS keystore is not supported on Linux, so the software will simply fallback to file keystore. However, some validators using Ledger may operate their key on local machine, and for macOS users, the default keystore is the one from the OS. Therefore when migrating the key onto Linux server, users may find that they are not able to find the key from the .liked
folder. In this case, the --keyring-backend file
option may help.
