The Problem

If you create a new repository in gitblit then you are not able to choose the master branch. Therefore you cannot check out anything.

The Solution

The answer to this behaviour is simple: You can not select a default branch because there is no default branch. The solution is …

1. Create the repositpry in gitblit (without choosing a default branch)
2. Create a local repository
3. Connect the repositories by telling the local repo where his remote friend is
4. Push the local master to the remote repo

For all of you who prefer to see the pure commands - here they are:

Make a new directory and initialize it as git repository

gue@gue-thinkpad:~/test$ mkdir MyNewRepo
gue@gue-thinkpad:~/test$ cd MyNewRepo/
gue@gue-thinkpad:~/test/MyNewRepo$ git init
Initialized empty Git repository in /home/gue/test/MyNewRepo/.git/

Now you can add your source code files or whatever.

Commit against your local repository

gue@gue-thinkpad:~/test/MyNewRepo$ git add -A
gue@gue-thinkpad:~/test/MyNewRepo$ git status

Initial commit

Changes to be committed:
  (use "git rm --cached <file>..." to unstage)

 new file:   build.sh
 new file:   content/client-server.png
 new file:   templates/postfix.md
 new file:   templates/prefix.md
.
.
.

gue@gue-thinkpad:~/test/MyNewRepo$ git commit -m "First version"
[master (root-commit) b962064] First version
 29 files changed, 791 insertions(+)
 create mode 100755 build.sh
 create mode 100644 content/client-server.png
 create mode 100644 templates/postfix.md
 create mode 100644 templates/prefix.md
.

.

Use this repository as any other.

Connect the remote gitblit repo and push the changes

$git remote add origin https://username@gitblit.host.com/r/MyNewRepo.git

$ git push origin master

From now on all changes are saved in your gitblit repo.

Depending on your setup of gitblit the URLs and authentication may look different from this example.
