Snowflake proxy standalone

Hello, I am trying to standup a standalone Snowflake proxy server to help people circumvent censorship but when following instructions from Tor Project | Standalone Snowflake proxy
After running command “go build” I get the following error:

main.go:13:2: cannot find package “git.torproject.org/pluggable-transports/snowflake.git/v2/common/event” in any of:
/usr/lib/go-1.10/src/git.torproject.org/pluggable-transports/snowflake.git/v2/common/event (from $GOROOT)
/root/go/src/git.torproject.org/pluggable-transports/snowflake.git/v2/common/event (from $GOPATH)

/root/go/src/git.torproject.org/pluggable-transports/snowflake.git/v2/proxy/lib (from $GOPATH)

I couldn’t find many documents regarding this installation and the above error.
Could you please help?
Thanks

Update: I retried the same installation on Ubuntu version 22 which resolved the issue but now I don’t know how to run Snowflake where it says “Run the Snowflake proxy” in the instructions. Also is there any Post-install documents I can follow and make sure server is running, active, its fingerprint and to see connections and bandwidth usage?
