5.10 networks don't work anymore

Hello one and all.

After upgrading to 5.10 (from 5.8.5) my networks do not work anymore. I get:

Ubuntu 18.04.

Any ideas how to fix this?

cheers, t.

Hi @himbeere,

It looks like you missed to sync the hosts after the upgrade?

Try with the following command to delete any leftover files too…

su - oneadmin -c 'onehost sync --force --rsync'

Hope this helps,

Thanks @atodorov_storpool
