LINUX Mint gvfs-set-attribute does not work although installed

Question

gvfs-set-attribute: Befehl nicht gefunden.

The last text means: command not found. Why? gvfs seems to be installed. ('installiert' means 'installed')

oliver@oliversNotebook:~/Projekte/BBB$ sudo apt list -a --installed gvfs
Auflistung… Fertig
gvfs/jammy-updates,now 1.48.2-0ubuntu1 amd64  [installiert]
gvfs/jammy 1.48.1-4 amd64

Also 4 more gvfs packages like gvfs-fuse and so are there.

These script already worked like a charm in UBUNTU 18.xx. In Mint it doesn't.
