You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain the commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

=> Compressing and cleaning up git repository

=> Appending nvm source string to /root/.bashrc
=> Appending bash_completion source string to /root/.bashrc
=> Close and reopen your terminal to start using nvm or run the following to use it now:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

Update your shell ~/.profile by running following command

source ~/.profile

Next, Check if NVM is installed or not by checking for its version.

nvm --version

Output:

root@crown:~# nvm --version
0.33.8

List out all available Node.js versions. you can see all Node.js versions from the first version to the latest version.

nvm ls-remote

Output:

root@vps:~# nvm ls-remote
        v0.1.14
        v0.1.15
        v0.1.16
        ....
        v13.12.0
        v13.13.0
        v13.14.0
        v14.0.0
        v14.1.0
  v15.0.0
  v15.0.1
  v15.1.0
  v15.3.0
  v16.3.0
  v16.4.0
  v16.4.1
  v17.9.0
  v17.9.1
  v18.0.0

Now install Node.js with the version you want by running "nvm install" command.

eg: Here 18.11.0

 nvm install 18.11.0
