See issue golang/go#34540
Seems this is fixed in 1.12.10. I suggest we should update to 1.12.10 first

I believe that we also need to update pouch linter as well. @allencloud see dragonflyoss/linter#20

I believe that we also need to update pouch linter as well. @allencloud see pouchcontainer/pouchlinter#20

I have release a new version 0.2.4 of pouchlinter, see https://github.com/pouchcontainer/pouchlinter/blob/v0.2.4/Dockerfile#L23.
And I also have pushed image pouchcontainer/pouchlinter:v0.2.4 to dockerhub.

Please check. If it is OK, I think we could close this, right>
If not, please feel free to contact me. Thanks. @yeya24
