# github.com/opencontainers/runc | link: duplicated definition of symbol sync.OnceValue[go.shape.bool].func2, from github.com/cyphar/filepath-securejoin and github.com/moby/sys/userns

I've checked out all combinations bertween runc, filepath-securejoin and userns and always get the link: duplicated definition of symbol sync.OnceValue. How can I resolve this conflict? Thanks a lot.

I guess you mean you get the error (which is in the title). Could you please describe what you do to get to this error, as well as list the versions of the components involved (runc, go).

I used Go 1.20.5 with runc 1.1.14 which does not depend on g.yxqyang.asia-moby-sys-userns and it works for a long time without sync.OnceValue.
I need to upgrade to Go 1.22.12 and all runc 1.2.[0-5] depends on userns and filepath-securejoin. I have checked all runc/go.mod for versions of filepath-securejoin and userns and I have not found the solution avoiding the sync.OnceValue conflict between them.
I have othe Go package that depends on runc which includes both filepath-securejoin and userns. I think they cannot co-exist for runc 1.2.* Thanks.
