i managed to update systeme via console / terminal

sudo apt-get update && sudo apt-get dist-upgrade

root@vps:~# yunohost -v
yunohost: 2.7.2
yunohost-admin: 2.7.2
moulinette: 2.7.2
ssowat: 2.7.2

maybe this commands shall be added as a tip for people who don’t manage just to make update via online web interface

great, i fixed with update of system and yunohost

apt-get update
apt-get dist-upgrade

thank you !
