I followed the manual steps in the link due to my network issue.

ldd not showing any output is strange. What's the result of these commands:

If I was you, I will try below steps.

download binary and check sha256sum

  1. go to ollama release page, download latest ollama-linux-amd64 and sha256sum.txt
  2. run sha256sum ollama-linux-amd64 and compare output with value in sha256sum.txt

some reasons I guess

  1. check if ubuntu 22.04 should install/update pkgs such as build-essential
sudo apt install build-essential
  1. check cpu and memory
    From the output of your shell root@i-2y1kobn5, It seems you are using a Cloud Computing Instance. Maybe a VM or a docker container. You'd better check if cpu and memory resource is enough to run ollama.
