Ubuntu 20.04

gsloop

So, yeah, I know Ubuntu 20.04 just dropped, and there’s not a lot of experience with it yet.
However, if anyone has data, I’d appreciate any feedback you can offer.

I did an install of MC, and used the stock Ubuntu 20.04 docker package.
The distro version of Docker is 19.03.8 and compose is 1.25.0
These all seem pretty current.
Is there any reason not to use the distro version now that it’s pretty current? [There’s all the advantages of using the distro version, in terms of security updates/patches/stability etc - and I’d like to keep those, unless there’s some huge issue with using the distro version.]

MC seemed to install fine - and while I haven’t’ done a ton of testing, I can get into the Control panel and manipulate things, so it seems like all is good.

Glad for any thoughts.

Well for now the docker.io has the same version than the current docker-ce package but that will change sooner or later when docker pushes a new docker-ce version in the next weeks
The best is to use the docker-ce version, which is not available for focal yet, but will change when theres a new update.

Just compare the 18.04 Ubuntu package with the current docker-ce one: https://packages.ubuntu.com/search?suite=bionic&searchon=names&keywords=docker.io

We suggest to use the latest docker-ce version at all time to avoid security flaws which may not be updated on the orginal Ubuntu repositories.

I can see a recommendation to use the CE version instead of distro for compatibility [with MC as future development happens] reasons, but not for security ones. Security issues should be patched and back-ported by Ubuntu during the distros supported life-cycle.

Perhaps docker is somehow different on security patches for Ubuntu, but if so, it’s the first I’ve heard of it.

Not tested yet. Waiting for official Docker packages (which are the only support versions for many reasons). Check https://download.docker.com/linux/ubuntu/dists/

While I doubt it, networking can be dangerously broken.

Currently running Mailcow on Ubuntu 20.04 with Docker CE packages (not Ubuntu). Everything seems to work fine.

Did you just install with packages for another distro? That’s exactly what’s dangerous. In CentOS 8 it is dangerous.

Did you check all NATing? If it starts and mails, it does not indicate it is working properly.

Just don’t do stuff, that’s not supported…

Nvm there seem to be stable packages now: https://download.docker.com/linux/ubuntu/dists/focal/
