The version that is already installed on my server is v64, and I want to update it to v65. I ran the following instruction on my terminal server, but I got the following error:
`curl -s https://mailinabox.email/setup.sh | sudo bash
fatal: not a git repository (or any of the parent directories): .git
bash: line 76: [: v65: unary operator expected
bash: line 87: setup/start.sh: No such file or directory
Please help me.
