Oh, thx for the pointer, "status" was added by mistake.

I was in the "belief" (*sigh*, sorry!), that the service can not be
stopped, once the service file / package has been removed. I took the
error message as is.

FTR, this it how it looks like after the packages is removed (and after
the user service was started before):

  ❯ sudo apt remove xdg-desktop-portal

  ❯ ps -ax | grep xdg-desktop-portal

Ok. After all, the user one *can* manually stop the service after the
package has been removed.

And: "Failed connect to PipeWire: Couldn't connect to PipeWire" was
also not shown anymore, after I started "xdg-desktop-portal".

All is good. Please close the bug (and mark it as obsolete/invalid, if possible.
I could not find how to do it).

Thx for your support!
