Hi @AlphaLynx,

That was it! I just issued rustup update and after it completed updating all components, I could build proton-authenticator seamlessly. Thanks for guiding me to resolve this issue. Much appreciate it!

@Musikolo I see the issue, you have cargo 1.86.0 (adf9b6ad1 2025-02-28). When rustup package is installed, your cargo and toolchains are installed in your home directory, and don't get updated with the system. So you need to specifically update the Rust toolchain with rustup update. for more info see here.

@AlphaLynx, I repeated the whole process again, and before getting started, I updated my box to latest and rebooted. First, I tried with rustup and the same problem occurred. Then, I replaced rustup with rust and it worked seamlessly. I got some details of each of the setups which shows different cargo versions and targets available:

• rustup 1.29.0-2: pastebin here.
• rust 1:1.95.0-1: pastebin here.

I hope it helps.

@Musikolo I can't reproduce that error. looks like the error means your cargo doesn't recognize 'host-tuple'. That was added in cargo 1.91.0 (https://doc.rust-lang.org/nightly/cargo/CHANGELOG.html#cargo-191-2025-10-30), so maybe you have an older version? try updating, rustup update stable

@AlphaLynx, it looks like builds fail if the host machine has the rustup package installed:

I was able to build it by uninstalling it which uses rust as the default package for cargo. However, it would be appreciated if a workaround could be found for this.

Thanks!

This package fails to install. To fix it, I needed to add export SENTRYCLI_SKIP_DOWNLOAD=1 before yarn install. Can you please fix this issue?

@Evrenos the only reason I have nodejs-lts as a makedepend instead of nodejs is because upstream lists LTS as a prerequisite in the monorepo. I think the package will still build fine with non-LTS nodejs, but it's probably better to use the dependency that upstream says, in case there is some incompatibility between versions.

edit: with nodejs v25 there's some breaking change, so using the LTS version is important

sorry if this is a dumb question, but why are you using nodejs-lts-jod instead of the regular nodejs? not complaining or anything, I'm just pretty new to this stuff

Thanks so much
