git pull remote branch cannot find remote ref

Be careful – you have case mixing between local and remote branch!

Suppose you are in local branch downloadmanager now (git checkout downloadmanager)

You have next options:

1. Specify remote branch in pull/push commands every time (case sensitive):

   git pull origin DownloadManager

   or

   git pull origin downloadmanager:DownloadManager

2. Specify tracking branch on next push:

   git push -u origin DownloadManager

   (-u is a short form of –set-upstream)

   this will persist downloadmanager:DownloadManager link in config automatically (same result, as the next step).

3. Set in git config default remote tracking branch:

   git branch -u downloadmanager origin/DownloadManager

   (note, since git 1.8 for branch command -u is a short form of –set-upstream-to, which is a bit different from deprecated –set-upstream)

   or edit config manually (I prefer this way):

   git config --local -e

   -> This will open editor. Add block below (guess, after “master” block):

   [branch "downloadmanager"]
           remote = origin
           merge = refs/heads/DownloadManager
   

and after any of those steps you can use easily:

git pull

If you use TortoiseGit:
RightClick on repo -> TortoiseGit -> Settings -> Git -> Edit local .git/config
