Check Update wont work

currently installed 2.129 on x86

the is a newer version avaible

but when i hit Check Updates, nothing happens?

can i do a mannually update?

apt-get update
apt-get upgrade
apt-get update

restart and try to use WebGui

This is at best the worst thing to do. Volumio definetely allows you to upgrade, but you will most likely break your system

If I am so wrong I would like to apologize for this statement, so please what would you suggest!?
