Error installing Dokploy on Ubuntu 26.04 #4349
Description
To Reproduce
Hello,
I wanted to install Dokploy automatically using the official install command:
curl -sSL https://dokploy.com/install.sh | shbut on a fresh Ubuntu 26.04 server the installation failed with the following error:
INFO: Searching repository for VERSION '28.5.0'
ERROR: '28.5.0' not found amongst apt-cache madison results
sh: 214: docker: not found
Error: Failed to initialize Docker Swarm
Current vs. Expected behavior
It seems Docker was not installed correctly during the automatic installation process, so Dokploy could not continue.

Hi @Mrahmani71! I'm Dosu and I’m helping the dokploy team.
This is a duplicate of #4327 — the root cause is that Docker's official repository doesn't support Ubuntu 26.04 (
resolute) yet. Dokploy's install script delegates Docker installation to Docker'sget.docker.comscript [1], which fails because there are no packages available for theresolutecodename.As a workaround, install Docker manually using the Ubuntu 24.04 (
noble) codename before running the Dokploy installer:Then re-run
curl -sSL https://dokploy.com/install.sh | sh— it should detect Docker is already installed and skip that step.To reply, just mention @dosu.

fix(setup): use Docker 29.4.2 on Ubuntu 26.04 to fix install failure
chore(release): 0.42.0 [skip ci]
