Install from Scratch - Lemmy Documentation
join-lemmy.org

I’m trying this on Ubuntu 22.04 Rust’s cargo install seems to keep creating permission problems between what I have to install, compile and what gets published in the cargo “registry”, which causes issues at runtime when I run as lemmy:lemmy through systemctl.

If I run: cargo install lemmy_server --target-dir /usr/bin/ --locked --features embed-pictrs as a non-root user, I get permission denied issues with /usr/bin/.future-incompat-report.json and /usr/bin/release

If I run the build as a root user, and then manually copy the binaries to /usr/bin and chmod them to lemmy:lemmy, then try to run as lemmy:lemmy, it appears the binary is trying to access some “registry” files in /root/.cargo/registry (for which of course it does not have permissions.)

How do I fix this?

    Here’s how I do it. Might be worth giving it a shot. This is on FreeBSD, but I doubt that matters.

    git clone https://github.com/LemmyNet/lemmy.git lemmy
cd lemmy
git checkout 0.17.3
git submodule init
git submodule update --recursive --remote
echo "pub const VERSION: &str = \"$(git describe --tag)\";" > "crates/utils/src/version.rs"
cargo build --release
strip target/release/lemmy_server

    Then copy target/release/lemmy_server to wherever you want to run it.

      Thanks. On cargo build --release I get this

        I was able to follow these build from git checkout instructions on Ubuntu 22.04, I didn’t get the error you got.

        What version of rust/cargo are you using? cargo --version I get:
        cargo 1.70.0 (ec8a8a0ca 2023-04-25)

        Yes, my instructions above are only for Lemmy. Here’s my complete setup.

        1: Build Lemmy
cd /root
git clone https://github.com/LemmyNet/lemmy.git lemmy
cd lemmy
git checkout 0.17.3
git submodule init
git submodule update --recursive --remote
echo "pub const VERSION: &str = \"$(git describe --tag)\";" > "crates/utils/src/version.rs"
cargo build --release
strip target/release/lemmy_server

2: Build lemmy-ui
cd /root
git clone https://github.com/LemmyNet/lemmy-ui.git --recursive lemmy-ui
cd lemmy-ui
git checkout 0.17.3
yarn install --pure-lockfile
yarn build:prod

3: Built pict-rs
cd /root
git clone https://git.asonix.dog/asonix/pict-rs.git pictrs
cd pictrs
git checkout v0.3.3
cargo build --release
strip target/release/pict-rs

        I’m running the binaries generated from those instructions at my own instance. Again, this is FreeBSD, not Linux, so your results may vary. I can’t imagine there’s any real difference though. I suspect the errors you’re getting are due to missing dependencies on your OS.
