For some time after the reboot , I get "kubectle get node " reply, later after do not get reply

Dear All,
Good morning
I have this doubt, is it because of my repository mismatch this issues is happenining
my repo for kubernetees is

cat /etc/apt/sources.list.d/archive_uri-http_apt_kubernetes_io_-jammy.list
deb http://apt.kubernetes.io/ kubernetes-xenial main

my host is Ubuntu 22.04 ( jammy ) and in my repo it is pointing towarrds xenial (Ubuntu 16.04) , would this be the reason for the crashing of my services
Thanks
Joseph John
