Update Factorio mods on a server: one or all at once

Update one Factorio mod with Update to version, or every mod with Update all, from the Mods page. The server restarts to apply them, so plan for players.

Updated , checked on Factorio 2.1.24

Open Mods and look at the Installed tab. When a mod has a newer release, the page says “(count) mods have a newer release” with an Update all button. To update one mod, open its row menu and choose Update to (version). Both stop the server, put the new files in place and start it again.

Before you update

  • Players must have exactly the same mods as the server to join. After an update, each player needs the new version of the mod too.
  • The server only takes releases made for its own Factorio version (major and minor, for example 2.1). If a mod has no release for that version, it is not offered.
  • Downloads come from the mod portal, so the server needs its own factorio.com account. See mod download refused.
  • A mod you uploaded yourself is not updated here. Upload the newer file instead. See upload a mod.

Update one mod

  1. Open Mods, then Installed.
  2. A mod with a newer release shows a chip such as “(version) out”.
  3. Open More for (name) on its row.
  4. Choose Update to (version).
  5. A box titled “Install (name)?” lists what it will download. Choose Install.

Update every mod

  1. In the banner “(count) mods have a newer release”, choose Update all.
  2. Read the box, then choose Install.

If every mod is already on its newest release, the panel says “every mod is on its newest release for this game version” and does nothing.

What happens next

The server stops, the new files are checked against the portal’s checksums and put in place, and the server starts again if it was running. The panel shows “Installing. The server stops, takes the mods and starts again.”

If it does not work

  • There is no Update to choice. The mod is up to date, was uploaded by you, or its newer release is not for this Factorio version.
  • The panel says “(name) (version) is not made for Factorio (version)”. The newest release does not fit the server’s game version. Keep the old one for now.
  • The server will not start after an update. The game says why at the start: a mod for another game version, or one that needs a mod the server does not have. See a mod could not load.
  • Update all is missing. Your role may not allow installing.
  • The page says the portal’s list is still loading. Wait a minute and try again.
