Hello, I reinstalled my Raspberry Pi 4 today with the latest DietPi firmware because I was having problems with Portainer after the last updates. Now I’ve discovered that a clean installation produces the same error. When I enter IPaddress.local:9002/, I see the dashboard (after login) and my envoirement, which shows “Up.” But when I try to access it, the icon changes from “Up” to “Down,” and I see an error in the upper right corner: “Failed loading environment. The environment named local is unreachable.” Several users on GitHub are also reporting this problem. Is there already a solution, or what can I do?
Reference?
Solution found here in the forum
This is unrelated to DietPi. It’s Portainer using an old Docker API

just did a fresh install of Portainer v29.0.4 in a docker running on Rocky Linux 10 (AKA RHEL)
Same issue
This is an issue of portainer itself and not related to the operating system
You mean Portainer in Docker v29.0.4.
Btw, Portainer 2.33.5 was just released, which fixes the issue:
They did not fix it as elegantly as Traefik, which did it with automatic client-server API version negotiation. Portainer just raised the static API version:
Hence everyone can now update their Portainer image and remove the workaround.

Shouldn’t
dietpi-software reinstall 185
also update Portainer to 2.33.5?
For me it doesn’t.
It stays on 2.33.2.
Yes it should. Can you paste the output of the dietpi-software run? Maybe we need to define @latest tag explicitly.

This command does not work anymore, hence the image is never removed:
docker image ls -a | mawk '/portainer\/portainer(-ce)?( |$)/{print $3;exit}'
Looks like this commit which was meant as enhancement to support Portainer BE upgrades, turned now into a bug fix at the same time: dietpi-software: Portainer: handle BE correctly by MichaIng · Pull Request #7832 · MichaIng/DietPi · GitHub
When I implemented this, the previous command still worked. What changed it:
- The image name is now suffixed with the version/tag.
- The image ID is now 2nd field instead of 3rd
Funnily I implemented exactly what they suggest now, before this warning was even emitted: using the --format option, as well as the --filter/-f one, instead of using mawk 
.
@Pi-Rate try this, the code a reinstall will run next DietPi version:
# Remove existing container and image, including CE, BE, and old v1, and store image repo in variable to preserve BE instances
container=$(docker container ls -aqf 'ancestor=portainer/portainer' -f 'ancestor=portainer/portainer-ce' -f 'ancestor=portainer/portainer-ee')
[[ $container ]] && G_EXEC docker container rm -f "$container"
read -r image repo < <(docker image ls -af 'reference=portainer/portainer' -f 'reference=portainer/portainer-ce' -f 'reference=portainer/portainer-ee' --format '{{.ID}} {{.Repository}}')
[[ $image ]] && G_EXEC docker image rm "$image"
# Create volume if it does not exist yet
[[ $(docker volume ls -qf 'name=^portainer_data$') ]] || G_EXEC docker volume create portainer_data
# Deploy new Portainer container, migrate v1 to CE and preserve BE
[[ $repo == 'portainer/portainer-ee' ]] || repo='portainer/portainer-ce'
G_EXEC_OUTPUT=1 G_EXEC docker run -d -p '9002:9000' -p '9442:9443' --name=portainer --restart=always -v '/run/docker.sock:/var/run/docker.sock' -v '/etc/ssl/certs/ca-certificates.crt:/etc/ssl/certs/ca-certificates.crt:ro' -v 'portainer_data:/data' "$repo"
