Factorio - Permissions Not Allowing Mods to be Initiated

Technical Support
1

OS Name/Version: Ubuntu 20.04.4 LTS x86_64

Product Name/Version: AMP Release “Triton” v2.3.2.8, built 28/03/2022 15:21

Problem Description: Factorio instance is not recognizing mods due to an permissions error during initilization:

Error ModManager.cpp:163: writeModlist threw an exception: filesystem error: create_directories "/mods" failed: Permission denied [/mods]

Steps to reproduce:

Error is reproduced whenever default.zip save is deleted and server performs first-time setup for a new save. The permission error is not thrown when loading a previously established save, but the mods are not being recognized either.

Actions taken to resolve so far:

Double checked file tree to ensure mods are in correct location.
Double checked a proper mod-list.json is present, with desired mods, and in correct location.

How did you add the mod files?

3

Downloaded from mods.factorio.com and uploaded through SFTP.

4

Using AMPs built in SFTP? Or your system SFTP? If the latter - what user did you log in as?

5

Same user as I logged into panel with, used the SFTP address provided by AMP.

I think you’ve got something wrong in a configuration somewhere, it looks like it’s trying to write to /mods which would be in the root of your file system. It should probably ./mods or mods/.

I figured it out, had a mod dependency I didn’t know about.

After I figured that out, I created a fresh instance and the mods worked completely normally.

Thank you for the prompt replies earlier.
