Hi Mathieu, FYI, see the link below. https://github.com/open5gs/nextepc/issues/181 Perhaps many people are confused the NextEPC name. I'm still less prepared, but let me send my next plan in a separate email. Thanks a lot!

(only 14 commits in the repo) There are nextepc packages in the universe ubuntu repo too now, but I don't know which version it is. Any idea ? Which project should be used ? Thanks, Mathieu
