Hi, Erwan and Gilles. Thanks for your replyes. It seems that my problem had to do with the network configuration. In this notebook where I am trying to install Docker I had at that time an active OpenVPN connection. It seems that this issue was mentioned in #779 for libnetwork. A workaround was: stop OpenVPN, install Docker, start OpenVPN (*) Curiously, may think that if I uninstall Docker while the VPN is active and then I install it again, I should have the same problem; but it was not the case. It seems that once having performed the procedure referred in (*), it was sufficient. Do you know why can this be? On the other hand, I rechecked the syslog: ---------------------------------------------------------------------- # grep docker /var/log/syslog Jul 9 09:06:55 orion systemd[1]: [/lib/systemd/system/docker.service:19] Unknown lvalue 'Delegate' in section 'Service' Jul 9 09:06:55 orion systemd[1]: [/lib/systemd/system/docker.service:19] Unknown lvalue 'Delegate' in section 'Service' Jul 9 09:06:55 orion systemd[1]: [/lib/systemd/system/docker.service:19] Unknown lvalue 'Delegate' in section 'Service' Jul 9 09:06:55 orion systemd[1]: [/lib/systemd/system/docker.service:19] Unknown lvalue 'Delegate' in section 'Service' Jul 9 09:06:55 orion docker[18248]: time="2016-07-09T09:06:55.898384570-03:00" level=info msg="New containerd process, pid: 18253\n" Jul 9 09:06:56 orion docker[18248]: time="2016-07-09T09:06:56.906426875-03:00" level=info msg="[graphdriver] using prior storage driver \"aufs\"" Jul 9 09:06:56 orion docker[18248]: time="2016-07-09T09:06:56.963054171-03:00" level=info msg="Graph migration to content-addressability took 0.00 seconds" Jul 9 09:06:56 orion docker[18248]: time="2016-07-09T09:06:56.973795286-03:00" level=info msg="Firewalld running: false" Jul 9 09:06:57 orion docker[18248]: time="2016-07-09T09:06:57.199871766-03:00" level=info msg="Default bridge (docker0) is assigned with an IP address 172.17.0.0/16.
