Error installing cmdeploy run [:80 bind: address already in use - acmetool]

lex2117 · November 28, 2025, 1:38pm

Good afternoon. When I run cmdeploy run, the process runs fine until the certificate request. It fails with an error (failed to listen on :80: listen tcp :80: bind: address already in use).
The port is busy. Has anyone encountered this?
Debian 12

Is there any other service running on the remote machine? It looks like there is a default web server running on port 80.

lex2117 · November 30, 2025, 3:09pm

Acmetool is running on port 80.

steko · November 30, 2025, 4:13pm

Then I think you should try to stop it (or even disable it):

sudo systemctl stop acmetool

And try again with the cmdeploy run command.

lex2117 · November 30, 2025, 4:28pm

acmetool runs during installation.
acmetool is not installed before running the script.

can you post the full log output of cmdeploy run? the acmetool output is pretty messy and has a lot of irrelevant error lines, the address already in use, while typically a red flag, is often not the significant one with acmetool.

The same issue.
