Backblaze activation failed

Related packages backblaze-b2 Running latest 1.3.8-4

Package of backblaze-b2 installed on the system, but when I put API credentials I got error

Failed to save cloud storage provider : Login to Backblaze failed : Backblaze command b2 or b2-linux is not installed

Nothing found in the system logs, or may be I’m looking in wrong place…

This has come up before and solved.
