Getting strange error when updating on Linux

I am programming on a Raspberry Pi3B with the latest Pi-OS Linux.
I have installed subversion via apt two days ago and got version
1.10.4 (r1850624).

When I want to update a project on this machine I get the following
output, which makes no sense to me (I have obfuscated the svn server
name)....

$ svn up
Updating '.':
Authentication realm: <https://svnserver:443> VisualSVN Server
Password for 'bosse': *********

** Message: 14:45:45.612: Remote error from secret service:
org.freedesktop.DBus.Error.ServiceUnknown: The name
org.freedesktop.secrets was not provided by any .service files
U source/class_SSRemoteServer.pas
U Readme.md
Updated to revision 4379.

If I do the same on an Rpi4 with a current Raspbian Linux using the
same client subversion version I do not get this message, it just
works...

So what could be the problem here? It seems to work, yet it outputs
this message...

What is this freedesktop thing?

And another thing:
On other RPi units I use the svn password is cached so I don't have to
enter it again and again, but not on this box, why?
