git - fatal: unknown value for config 'protocol.version': 2

Question

I decided to turn on Git protocol 2nd ver (I suppose it's faster, noiseless), so I did:

git config --global protocol.version 2

But when I try

git pull

I get an error saying:

fatal: unknown value for config 'protocol.version': 2

My OS is Ubuntu 18.04. My friend on Ubuntu 16.04 did the same and it worked for him. Am I maybe missing some dependencies?

Answer 1

This feature appeared in Git 2.18

To try out protocol version 2 for yourself you'll need an up to date version of Git (support for v2 was recently merged to Git's master branch and is expected to be part of Git 2.18) and a v2 enabled server (repositories on googlesource.com and Cloud Source Repositories are v2 enabled).

And I have Git 2.17v
