Hi @pacoxu. Thanks for your PR.

I'm waiting for a containerd member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Another two places using latest ubuntu are like below:

/Users/xupaco/git/gopath/src/k8s.io/containerd/.github/workflows/codeql.yml:
   19:     runs-on: ubuntu-latest

/Users/xupaco/git/gopath/src/k8s.io/containerd/.github/workflows/nightly.yml:
   12:     runs-on: ubuntu-latest

https://github.com/pacoxu/containerd/blob/master/.github/workflows/ci.yml#L40-L68

Test the ci in ci.yaml in my repo: https://github.com/pacoxu/containerd/runs/2164779752?check_suite_focus=true

LGTM

use ubuntu-18.04 as the latest now is 20.04

Could you fix the commit message (git commit -a -s --amend)? LGTM then.
