I can confirm this, I needed to delete the IPv6 ULA-Prefix in my openwrt wlan router to disable IPv6 autoconfig of LAN devices.

Wah, Thank you @mrmarkuz and @stephdl for tremendous Job.
How come i did not see this announcement before. the way i was stressing with Docker things. this is crazy.
Also, just curios, can i install and Run mailcow inside the docker container?
I suppose yes but a mail server is quite complicated and made from several pieces
Why is NEthserver docker not appearing in My software Center?
you have not upgraded to 7.8 ?
it is 7.8
It makes use of docker compose and port redirection that wants to use ports already in use by Nethserver. It installs 18 (!) containers and you need to change from port redirection to aeria bridge so it’s not easy to install.
https://mailcow.github.io/mailcow-dockerized-docs/i_u_m_install/
I can confirm it’s not listed, maybe with next update, please use cli (yum install nethserver-docker) as workaround.
Thank you for saving me the trouble.
I was about to begin installation. it would have givene me lots of headaches and wastade time, for not knowing what moving parts are required

Why would you want to? What does it do that Neth’s built-in mail server doesn’t?
Multi tenancy Email.
I have multiple small businesses that require email.
I am trying to figure out the best solution to use to offer them Email. As well as Nextcloud.
Mailcow because it can be used to authenticate nextcloud instances.
The businesses are too small, and deploying a single nethserver instance for each does not make sense, both for my management, and they dont have IT guys to manage that
Ontop of That i am also trying to figure out, if i can have multiple nextcloud instances running inside the portainer
Yep, a definite hole in Neth’s feature set.
No problem. It’s just that I’m really a noob using docker. I have to do my homework too

It’s been two times in a row that my docker installation breaks seemingly after an update :
The following updates will be applied on [myserver]
================================================================================
Package Arch Version Repository Size
================================================================================
Updating:
[containerd.io](http://containerd.io/) x86_64 1.2.13-3.2.el7 docker-ce-stable 25 M
docker-ce x86_64 3:19.03.10-3.el7 docker-ce-stable 24 M
docker-ce-cli x86_64 1:19.03.10-3.el7 docker-ce-stable 38 M
Transaction Summary
================================================================================
Upgrade 3 Packages
The updates were successfully applied
After that the docker service can’t restart. After a reboot it worked again but not the machines connected to the Aeria network : Portainer reports failed to add endpoint: plugin devplayer0/net-dhcp:latest found but disabled
syslog extract at (automatic) update time : https://pastebin.com/362H6rXr
Last time I ended up completely removing docker packages and all remaining files on the disk to get it working again.
What do you think ? Anybody else having that problem ?
Congratulations and thanks for that release. This is excellent and looking forward to trying to deploy Nethserver under docker!
It seems the dhcp plugin gets disabled after docker-ce update.
As a workaround you may reenable it with
docker plugin enable devplayer0/net-dhcp
or by running the plugin update
signal-event nethserver-docker-plugin-update
Thanks for pointing out.
I think we could enable the plugin with signal-event nethserver-docker-update. But one still needs to run it manually.

Indeed, it’s working.
The segmentation errors are weird.
This may prove being a major problem in production however.
Thanks.
