ceph-fuse 14.2.5-3ubuntu2 (amd64 binary) in ubuntu focal

 Ceph is a distributed network file system designed to provide
 excellent performance, reliability, and scalability. This is a
 FUSE-based client that allows one to mount a Ceph file system without
 root privileges.
 .
 Because the FUSE-based client has certain inherent performance
 limitations, it is recommended that the native Linux kernel client
 be used if possible. If it is not practical to load a kernel module
 (insufficient privileges, older kernel, etc.), then the FUSE client will
 do.
