I fixed my problem with apt key be following this article -> signatures couldn't be verified, public key is not available NO_PUBKEY 88807D4B2221338C
And that's all good!
People that have problem with apt key should read that artice first !!!

But, I have now other problem.
After the update, i notice a problem to login to panel with the URL
https://xxx.com:8083/?myname
Shows: 502 Bad Gateway
nginx
Also, i receive an email from server:
Cron <admin@mysitel> sudo /usr/local/vesta/bin/v-update-sys-vesta-all
Error: vesta update failed
Error: vesta-nginx update failed
Error: vesta-php update failed
Does it change something on the session profile?
