Set your home dir first before installation (for setting the correct path)
export OLLAMA_HOME=/home/iamgini/.ollama
export OLLAMA_MODELS=/home/iamgini/.ollama/models
mkdir -p $OLLAMA_MODELS
Add those exports to ~/.bashrc permanently, then run the install script. The service and models will respect those paths.
Install ollama
curl -fsSL https://ollama.com/install.sh | sh
