Answer 1

I know this is a long time, but in my case, I used automatic rebase from gerrit interface to resolve simple conflicts. Maybe this introduce some changes between my local repository and the server one.
I simply had to sync with git to get those updates.
Using the git pull --rebase origin master worked for me.
