Git: Uptream is Gone

Javalobby Syndicated Feed - Thu, 26-Feb-15 23:30
I came across a git repo recently that output this message with every operation I did: Your branch is based on 'origin/master', but the upstream is gone. (use "git branch --unset-upstream" to fixup) I was delivering a workshop at the time so I kinda snarled at it and carried on with what I was doing, but later I looked up what is happening. This occurs when a branch is tracking a branch...
