Error: Loading needed libs in elf

[sandertan]

Hi! Awesome project! I'm currently running into an issue with the server not starting up correctly. I upgraded my OS libaries (because I thought it might be good to get some security updates), is that the cause? Should I destroy my infrastructure and redeploy it, or is there an other way to fix this? I'm still on Ubuntu 22.04 LTS; i only did apt-get update; apt-get upgrade.

This is the error:

Sep 19 20:41:40 instance-20250317-1639 systemd[700]: valheim_server.service: Scheduled restart job, restart counter is at 6.

Hi, thank you for raising the issue and the kind words.
With the Call to Arms update this started happening, and we found the issue only happened using Box86/64.
I'm in the process of changing out Box with FEX (will be the standard for the project very soon).
You can however already switch to using it by running the following command:
USE_FEX=true bash ./setup_valheim_server.sh

Edit: I forgot to add, this only replaces the x86/64 emulator while leaving the server data and saves untouched.
Also, in case you're started using the install script before the 9th of September, you might need to update it prior to running the command above (see Self-upgrade not working (14th Jan 2025 - 9th Sept 2025) for more information)

That solved it! Thanks for the clear instructions.
