Hello,

And when i copy latest release .tar.gz file link and try to download it: $ cd /mnt/tmpfs/ && wget https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/jobs/295269/artifacts/file/snowflake-.tar.gz

HTTP request sent, awaiting response... 404 Not Found

Can you fix that 404 file please, or if you have idea how to allow build on mine mentioned system?

In the meantime, i have tried to "go built" on a different (also Debian based - 5.10.0-20-amd64 x86_64 GNU/Linux) computer and copied resulting "proxy" directory to 6.1.28+ armv7l GNU/Linux computer: scp -r ../proxy/ user@192.168.1.10:/home/user/snowflake/

Yet it does not launch it: /home/user/snowflake/proxy/proxy: cannot execute binary file: Exec format error

Building using "GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build" mentioned in my previous issue and copying to othr computer also end in "Exec format error". On source, it launch ./proxy OK.
