Thanks

I tried (BTW my version is 2.26.2)

$ GIT_TRACE_PACKET=1 git -c protocol.version=2 pull -r

and the first few lines look like

Is there something else I need to do on the client-side to make this work?

Noting that the git server at gerrit.libreoffice.org might be a JGit based thing, so maybe I need to log a feature 
request there to support v2?
