git: Reference at 'refs/heads/master' does not exist

[ggiesen]

Environment

• Python version: 3.6.8
• Nautobot version: 1.0.1

Steps to Reproduce

1. Create git repo in GitLab
2. Assign user with maintainer status
3. Create personal access token
4. Add git repository to Nautobot with the following values:

• Name: nautobot
• Slug: nautobot
• Remote URL: https://host.example.com/nautobot.git
• Branch: master
• Token: <token>
• Username: oath2
• Provides: ["config contexts", "export templates", "jobs"]

Expected Behavior

Clone and sync the repository locally

Observed Behavior

Creating/refreshing local copy of Git repository "nautobot"...
Reference at 'refs/heads/master' does not exist
Error while refreshing nautobot: Reference at 'refs/heads/master' does not exist
Repository synchronization completed in 0 minutes, 0.06 seconds

Manually doing a git pull in Nautobot's local git repository (/opt/nautobot/git/nautobot/ in my case) solves the problem, and allows sync going forward

It seems like whatever repo you're attempting to clone down doesn't have a master branch. If it's Nautobot repo, it would be main.

When you're in the local directory and run a git branch, what branches does it show?

@ggiesen can you confirm you tried what @FragmentedPacket proposed and if this is still an issue?

[ggiesen]

Still an issue:

$ git branch
* master

The workaround is easy (doing one git pull before initial sync), but yeah, this should be fixed at some point

@ggiesen Was your repo empty at the time you attempted?

[ggiesen]

It may have been empty, though I thought it had at least a README.md.
