Q/A
#1

Hi, team
When I was installing free5GC according to wiki installation, I got a security error in step B.2, like this:

root@ubuntu:~/free5gc# make
Start building amf....
cd NFs/amf && \
CGO_ENABLED=0 go build -ldflags "-X github.com/free5gc/version.VERSION=v3.0.6 -X 
github.com/free5gc/version.BUILD_TIME=2021-09-27T09:32:15Z -X

github.com/free5gc/version.COMMIT_TIME=2021-09-24T09:44:32Z" -o /root/free5gc/bin/amf amf.go

SECURITY ERROR
This download does NOT match an earlier download recorded in go.sum.
The bits may have been replaced on the origin server, or an attacker may
have intercepted the download attempt.

For more information, see 'go help module-auth'.
make: *** [Makefile:44: bin/amf] Error 1
root@ubuntu:~/free5gc#

how do I solve the problem?

SECURITY ERROR still occurs when I Compile
#2

Hi,
This problem is about GO language. Please check your Go version is 1.14.4.
If the version is 1.14.4, try to use the following instructions:

go clean -modcache
go mod tidy

If the problem still occurs, remove free5gc and git clone again.
