Re: [ovirt-users] ovirt-guest-agent.service has broken in Debian 8 virtual machines after updates hosts to 4.2

Hello Ed. I found another way to solve the problem. But I do not know if it's the right way :( So I decided to ask a question here. But none of the gurus answered. # mkdir ~/packages # cd ~/packages # wget http://ftp.us.debian.org/debian/pool/main/o/ovirt-guest-agent/ovirt-guest... # apt-get install gir1.2-glib-2.0 libdbus-glib-1-2 libgirepository-1.0-1 libpango1.0-0 libuser1 python-dbus python-dbus-dev python-ethtool python-gi qemu-guest-agent usermode # dpkg -i ~/packages/ovirt-guest-agent_1.0.13.dfsg-2_all.deb # systemctl restart ovirt-guest-agent.service # systemctl status ovirt-guest-agent.service * ovirt-guest-agent.service - oVirt Guest Agent    Loaded: loaded (/lib/systemd/system/ovirt-guest-agent.service; enabled)    Active: failed (Result: exit-code) since Wed 2018-01-03 22:52:14 MSK; 1s ago   Process: 23206 ExecStart=/usr/bin/python /usr/share/ovirt-guest-agent/ovirt-guest-agent.py (code=exited, status=1/FAILURE)   Process: 23203 ExecStartPre=/bin/chown ovirtagent:ovirtagent /run/ovirt-guest-agent.pid (code=exited, status=0/SUCCESS)   Process: 23200 ExecStartPre=/bin/touch /run/ovirt-guest-agent.pid (code=exited, status=0/SUCCESS)   Process: 23197 ExecStartPre=/sbin/modprobe virtio_console (code=exited, status=0/SUCCESS)  Main PID: 23206 (code=exited, status=1/FAILURE) As we can see, the service does not start. In this case, the error in the log (/var/log/ovirt-guest-agent/ovirt-guest-agent.log) will be different: MainThread::INFO::2018-01-03 22:52:14,771::ovirt-guest-agent::59::root::Starting oVirt guest agent MainThread::ERROR::2018-01-03 22:52:14,773::ovirt-guest-agent::141::root::Unhandled exception in oVirt guest agent!
