1. Using Crates.io:

cargo install mollysocket

ends up with

error[E0658]: c"…" literals are experimental … error: could not compile rusqlite (lib) due to previous error.

Now rustc --explain E0658 states that this is due to unstable feature “repr128”. I’m using a nightly version.

2. Using precompiled release:

After systemctl enable --now mollysocket

performing systemctl status mollysocket gives

… Active: failed (Result: exit-code) … Process: … (code=exited, status=203/EXEC) …

3. Docker:

sudo -u mollysocket mollysocket vapid gen | systemd-creds encrypt --name=ms_vapid -p - -

or basically any command starting mollysocket ends up with

mollysocket:command not found error.

I’m currently running Linux Mint (though I’m okay and/or planning to change the distro once I succeed with this setup for the first time).
