The program /usr/local/bin/ollama is not the ollama server, it is too small and has the wrong sha signature.

I solved this problem by switching users, hoping to help you. Good luck
su -s /bin/bash ollama

@Tokarev-TT-33 commented on GitHub (Feb 18, 2025):

I solved this problem by removing the wrong symlink.

At first i got the same segmentation fault error

$ ollama --version
Segmentation fault

And I found multiple ollama path.

$ which ollama -a
/usr/local/bin/ollama
/usr/bin/ollama

Current wrong ollama is:

$ which ollama
/usr/local/bin/ollama

So i tried to remove the wrong link.

$ sudo rm $(which ollama)

And it works

$ ollama --version
ollama version is 0.5.11
