Public bug reported:
After openvpn has been upgraded automatically today, client VPN
connections are broken, getting no response from the server anymore.
After a restart of the openvpn service on the server, the issue is
fixed. Seen on multiple servers by me and others in #ubuntu-server. From
/var/log/apt/history.log:
Start-Date: 2017-06-23 13:57:41
Commandline: /usr/bin/unattended-upgrade
Upgrade: openvpn:amd64 (2.3.10-1ubuntu2, 2.3.10-1ubuntu2.1)
End-Date: 2017-06-23 13:57:42
Tried downgrade and manual "unattended-upgrade" again, could not
reproduce. In the syslog I can see that after the initial upgrade
openvpn got stopped again 4 seconds later:
