state: check-failed when running canonical-livepatch - Ask Ubuntu

i have installed canonical livepatch snap package:

sudo snap install canonical-livepatch sudo canonical-livepatch enable (and code) 

i setup unattended upgrades:

sudo apt install unattended-upgrades sudo dpkg-reconfigure unattended-upgrades 

however, when want check on livepatch status doing:

canonical-livepatch status --verbose 

i this:

client-version: "5" machine-id: a144ba7b92ec478495cc5918743fe0e7 machine-token: 46a92999127246328b5091f493ee7be0 architecture: x86_64 cpu-model: intel(r) core(tm) i5 cpu       m 430  @ 2.27ghz last-check: 2016-11-02t11:38:33.551353308+02:00 boot-time: 2016-11-02t11:40:22+02:00 uptime: 12m0s status: - kernel: 4.4.0-45.66-generic   running: true   livepatch:     state: check-failed     version: ""     fixes: "" 

should concerned state: check-failed message? if so, causing it, , how can fix it?

yes, should concerned. have problem too. best disable , re-enable livepatching every day (it works few hours, stops).

you can @ log:

# systemctl status snap.canonical-livepatch.canonical-livepatchd.service 

for reason, stops authenticate service after while:
