pull on cloned repo throws exception

[mtrachli0616144]

Hello,

I started using this library a couple of weeks ago and I am running into some issues.

I manage to clone the remote directory using the example from the doc. After wards, I perform various checkouts on remote branches in order to retrieve information useful for my app.
After a while, I would like to make a pull on the remote in order to make the local version up to date, again i use the example from the doc:

using (var repo = new Repository(@tmpRepoFolder))
{
PullOptions options = new PullOptions();
options.FetchOptions = new FetchOptions();
options.FetchOptions.CredentialsProvider = new CredentialsHandler(
(url, usernameFromUrl, types) =>
new UsernamePasswordCredentials()
{
Username = myUser,
Password = myPwd
});

            repo.Network.Pull(
                new Signature(myUsr, mail, new DateTimeOffset(DateTime.Now)),
                options);

}
The previous code throws an exception when executing the Pull with the following message:
{"There is no tracking information for the current branch."}

I looked for a bit inside the code and did some debugging. The issue seems to be that the Head property on the repo does not point to any branch(repo.Head.name = "no branch")

I noticed that this happens after the first call to checkout repo.checkout(branchName).

I am not sure this is actually a bug, but I am sure stuck for now. Can you please tell me what i am doing wrong here ?

Thanks

Pull uses the current branch as a way to know what it should do. If there is no branch, then you must specify where it is that it should fetch from and what branch to fetch.
