did you install it using community-scripts? If so reboot the container, otherwise ignore this 🙂

Can you post what CPU / host hardware you run?

i am running ubuntu server its on an amd x86_64 model is AMD Athlon(tm) II P340 Dual-Core Processor
Manicraft1001
Manicraft10012mo ago
I'm sorry, but that CPU is very old. It probably misses some instruction sets that are required for Nodejs 22, Nextjs and Homarr. Please run Homarr on a device with newer hardware.

oh i forgot i uninstall nodejs yesterday so i need to reinstall it again it works w/ the latest nodejs

Ok, that's good to know. Latest node probably implemented some workarounds or support for your platform

See https://github.com/homarr-labs/homarr/issues/2260#issuecomment-2642260748, that CPU likely has too old instruction sets. The error is from underlying libraries and we cannot do anything about it. Your CPU is also EOL: https://www.intel.com/content/www/us/en/products/sku/49490/intel-atom-processor-d525-1m-cache-1-80-ghz/specifications.html . Upgrade to a newer system to run Homarr
