Everything was working but suddenly I'm getting an error every time I run a docker container.


docker run -it debian

Resulting Error:

docker: Error response from daemon: failed to create endpoint dazzling_ptolemy on network bridge: failed to add the host (veth1e8eb9b) <=> sandbox (veth73c911f) pair interfaces: operation not supported

I have restarted docker using

systemctl docker restart

I also did a network prune

docker network prune

Nothing seemed to work, thank you for any help.


I haven't taken the time to figure out why, but you should just need to reboot your machine; it worked for me.

A search for the error on github came up with this, which links to this github issue from a while ago: https://github.com/moby/moby/issues/15341#issuecomment-218930712

    Yea, I forgot to update this but I restarted and it worked like a charm. Not sure why this happens. – Machiavelli Apr 29 '17 at 7:30

    For me this is caused by updating my kernel. I use an operating system that has a rolling release, in which kernel updates happen somewhat frequently. There's always a chance when i update my system that the kernel is updated and a reboot will be necessary in order for docker networking to work again. I hope this helps those who may wonder what causes this. I would love to find a way to avoid the restart. – Patrick Motard Apr 27 '18 at 16:06

    This is not a solution, but a workaround. – Nils Magnus Jul 26 '18 at 14:14

    Things like this make me want to leave computers behind and look into woodcutting – domenukk Apr 28 '19 at 4:28

    In my experience, this happens because I updated my system but I forgot to restart to load the new kernel and reinitialize the networking system. I think it's trying to load something that's for the new, non-running kernel. Just a thought. – Nathan Sep 30 '19 at 17:23
