Rsync Over Multiplexed SSH with Multiple Jumphosts

bashlinuxrsyncssh

I need to rsync a file from remote hosts to my local machine over multiple jumphosts. I'd like to use shared SSH connections so that I don't have to submit 2FA multiple times at some jumphosts.

The idea is I create a master connection

ssh user@jumphost01

then other connections

ssh -J user@jumphost01,user@jumphost02 root@target01
...

Shared connections control files in ~/.ssh/ look as follows

control:target01:22:root
control:jumphost01:22:user
control:jumphost02:22:user

Now I would expect I can rsync a remote file using

rsync -azv -e 'ssh -o ControlMaster=auto' root@target:/somePath/someFile someFile
or
rsync -azv root@target:/somePath/someFile someFile
or    
rsync -azv -e 'ssh -F /root/.ssh/config' root@target:/somePath/someFile someFile

but I'm getting rsync error

receiving incremental file list
someFile
WARNING: someFile failed verification -- update discarded (will try again).
someFile
ERROR: someFile failed verification -- update discarded.

sent 68 bytes  received 317 bytes  770.00 bytes/sec
total size is 305  speedup is 0.79
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1819) [generator=3.2.3]

Rsync is able to connect to the target but the file transfer is unsuccessful.

rsync versions

local machine - rsync  version 3.2.3  protocol version 31
target machine - rsync  version 3.2.3  protocol version 31

TLDR;

I tested the rsync command without SSH master connection as

rsync -azv -e 'ssh -J user@jumphost01,user@jumphost02' root@target01:someFile .
One-time password (OATH) for `user':

And still getting the same errors.

There were some issues with dynamically linked libraries.

# apt update && apt upgrade

on remote machine solved the issue.
