Your Docker installation is not using a supported storage driver. If we were to proceed you may have a broken install.
overlay2 is the recommended storage driver, although zfs and aufs may work as well.
Other storage drivers are known to be problematic.
You can tell what filesystem you are using by running “docker info” and looking at the ‘Storage Driver’ line.

If you wish to continue anyway using your existing unsupported storage driver,
read the source code of launcher and figure out how to bypass this check.

Can Not Instal Docker

I have try change my vps providers into digitalocean, and two other vps provider but still failed.

I thought it was my vps provider problem but after I try fresh installation in digital ocean with some fresh droplet and official/standard installation, still failed. Then I change into another two different vps providers, same. :face_with_raised_eyebrow:

I thought it was my Ubuntu version, but after I try Ubuntu version 24, 22, 20, and 18 still failed.

Anyone can help?

I can confirm this behavior on at least two sites I’ve set up recently. Something is wrong with git.docker.com and it fails to load overlay2 by default like it has for years.

Create /etc/docker/daemon.json with this content:

{
  "storage-driver": "overlay2"
}

then

sudo systemctl restart docker

It should work after that. You can check that it’s installed with

docker info --format '{{.Driver}}'

Me too…

I mean, currently, something wrong in official discourse installation process.

I have try digitalocean with official installation but this error message appear. Then I move to another vps provider, same.

I hope, anyone who struggle on discourse fresh installation in this November 2025 :sweat_smile:, will find above solution :index_pointing_up:

This is my third day struggling :tired_face: and done.

Thank you very much Mr. Jay :folded_hands:

Well, it’s docker’s fault. I keep thinking that they’ll fix it, but until I notice that they do, all of my installs create that file so I don’t have to worry about it.

I complained about it here:

Docker uses a new default storage driver for v29.0+

Docker Engine 29.0 and later uses the containerd image store by default for fresh installations. The containerd image store uses snapshotters instead of the classic storage drivers described on this page. If you’re running a fresh installation of Docker Engine 29.0 or later, or if you’ve migrated to the containerd image store, this page provides background on how image layers work but the implementation details differ. For information about the containerd image store, see containerd image store.

so then from what I’m understanding, we just need to also look for and include overlayfs?

PR for that here:

I don’t know. I didn’t test whether overlay would work. At some point, it didn’t, and that’s why it’s a requirement. It didn’t occur to me that it’s no longer a requirement.

Oh.

containerd image store seems to report as overlayfs, so we should allow for this string as well.
