Repo sync fails to initialize CM13 work tree

Question

whenever I try to sync CM13 sources, I get this error:

panos@ubuntu:~/android/cm13$ repo sync -l
Syncing work tree:  67% (344/512)  fatal: This operation must be run in a work tree
Traceback (most recent call last):
  File "/home/panos/android/cm13/.repo/repo/main.py", line 531, in <module>
    _Main(sys.argv[1:])

    result = repo._Run(argv) or 0
  File "/home/panos/android/cm13/.repo/repo/main.py", line 180, in _Run
    result = cmd.Execute(copts, cargs)

  File "/home/panos/android/cm13/.repo/repo/project.py", line 2393, in _InitWorkTree
    raise GitError("cannot initialize work tree")
error.GitError: cannot initialize work tree

...and here's "repo --trace sync -l"

    raise GitError("cannot initialize work tree")
error.GitError: cannot initialize work tree

I have already retried "repo sync" (what you see is "repo sync -l" which only syncs the work tree locally)

Any help is greatly appreciated. Thanks in advance :D

Answer 1

I've had the same problem. Here's how I fixed it:

1. Look at which project is causing the problem (In your case android/cm13/hardware/qcom/audio-caf/msm8996. From the second output you posted)

2. Delete the folder of that project (/home/panos/android/cm13/hardware/qcom/audio-caf/msm8996)

3. Delete the git directories for that project (/home/panos/android/cm13/.repo/projects/hardware/qcom/audio-caf/msm8996.git and /home/panos/android/cm13/.repo/project-objects/hardware/qcom/audio-caf/msm8996.git)

   4. Try running repo sync again.
