s3ql 3.7.0+dfsg-1 (arm64 binary) in ubuntu hirsute

 S3QL is a file system that stores all its data online using storage
 services like Google Storage, Amazon S3 or OpenStack. S3QL
 effectively provides a hard disk of dynamic, infinite capacity that
 can be accessed from any computer with internet access.
 .
 S3QL is a standard conforming, full featured UNIX file system that is
 conceptually indistinguishable from any local file
 system. Furthermore, S3QL has additional features like compression,
 encryption, data de-duplication, immutable trees and snapshotting
 which make it especially suitable for online backup and archival.
 .
 In addition to accessing online storage services directoly, S3QL can
 also store its data underneath a regular mount point. This enables
 the use of S3QL with e.g. NFS, CIFS or sftp servers.
