How do you downgrade to xtrabackup 2.0 from 2.1

is there an apt-get package for xtrabackup 2.0… i’m getting the following error with 2.1

Error: Support for mysql 5.1 with builtin innodb (not the plugin) was removed in percona xtrabackup 2.1


There is blog post about similar case:

It says that upgrading to latest Percona Xtrabackup should help.
Can yo please try that?

Getting a new error… please attached

Can you please try again?
