Github Actions — checkout error

When running this action to pull current branch code line into runner

- uses: actions/checkout@v2

Reference : https://github.com/marketplace/actions/checkout#Fetch-all-history-for-all-tags-and-branches

sometimes will pop-up this error message

Error: error: insufficient permission for adding an object to repository database .git/objects
87 Error: fatal: failed to write object
88 Error: fatal: unpack-objects failed

I find some ways to figure out the problem

1. add AutoModality/action-clean@v1
   Reference: https://github.com/marketplace/actions/clean-workspace
2. using another branch to trigger this event
3. Somebody mentioned…

- uses: actions/checkout@v2
  with:
  lfs: true
 token: ${{ secrets.ACCESS_TOKEN }}

4. Waiting for 10 second then checkout
Reference : https://github.com/actions/checkout/issues/417#issuecomment-842157976)

Finally, the methods 1 and 4 can figure out this problem

Example code…

steps:
 - name: clean workspace
   uses: AutoModality/action-clean@v1
 - name: sleep 10 sec
   run: sleep 10
 - uses: actions/checkout@v2

Because I using aws ec2 as self-host

the runner workspace folder role different

then I add following command to figure this problem

# sync folder owner
- name: sync owner
  run: sudo chown runner:runner -R .*
