"wget: command not found" when executing CurseForge start script.

[CursedDog19]

Describe the problem

Does the container have wget installed? The modpack I downloaded must use wget to fetch the forge server jar. Here is the modpack's included ServerStart.sh:

#!/usr/bin/env bash
# Start script generated by ServerPackCreator.
# This script checks for the Minecraft and Forge JAR-files, and if they are not found, they are downloaded and installed.
# If everything is in order, the server is started.

No, wget has long since been removed since people generally want the image to be as small as possible and there's already curl and mc-image-helper.

With that said, I can adjust the latter to the command line compatible but this is a low priority for me since supporting all these custom modpack scripts is a daunting amount of effort.

In case someone stumbles over this question in some distant future.

Here a small workaround by simply installing wget on startup (yes that increases startup time, but the other option is building your own image, which might be to bothersome)

entrypoint: > sh -c "microdnf install wget -y && /start" replace the package manager with whatever the selected distro provides
