As the team behind the various protocols and projects that utilize the Radicle network, we want you, the user, to have the best experience possible. Also, as the developers, we know that there will be bugs and errors.

To help consolidate these diametrically opposed pieces of knowledge, we will try and document any of the errors that we are aware of and provide some troubleshooting advice.

I ran into a issue — where can I report it?

We suggest you send your report through the #support channel on our Discord server or in the Support category of our forum. A member of the Radicle team will try resolve your issue right away, and if they can't, work with you on creating a formal issue/request.

If you know which Radicle project is most relevant to your issue, you can also create an issue in the appropriate repository on GitHub.

Installation prerequisites for rad

If you have trouble with installing the Radicle CLI, make sure you have installed the correct versions of the following:

  • Git: 2.34.0 or later
  • OpenSSH: 8.0 or later

Issues with ssh-agent

The following two errors are related to your cryptographic keys, which Radicle uses to authenticate your identity, not being properly managed by ssh-agent.

Fatal: the key is not in the ssh-agent, consider adding it via lnk profile ssh add
error: Load key "/tmp/.git_signing_key_tmp....": Invalid format

The most likely issue is that your system isn't running ssh-agent. After you get ssh-agent running using one of the two methods below, based on your OS, run rad auth once more to ensure your keys are properly added.

lnk profile ssh add
rad auth

When rad successfully loads a key into ssh-agent, it outputs the following:

ok Unlocking...
ok Radicle key added to ssh-agent
ok Signing key configured in git

Unsupported Git version

If you see the below error when using git after initializing a project, you're most likely running a version of Git that's incompatible with rad.

error: unsupported value for gpg.format

See our prerequisites for the minimum Git version number you need to run rad and access the Radicle network.

SLOP failure

When Git pushes a signed commit to a remote repository, it sends a nonce an arbitrary number only used once based on your system time as a security measure. If that nonce doesn't match with what the remote system expects, Git outputs this warning:

remote: Running pre-receive hook...        
remote: Verifying certificate...
remote: Received `SLOP` certificate status, please re-submit signed push to request new certificate
remote: Error: failed certification verification

There are two solutions:

  1. Push your code again using rad push.
  2. Check your system time for discrepancies.

Install Radicle CLI on Apple Silicon

Previously, installing rad on M1/M2-based systems required you to install the x86_64 version of Homebrew.

As of September 2022, you can install Radicle using our formulae repository whether you're on Apple Silicon or an older Intel-based system. If you're on Apple Silicon, rad will not run natively, but it will work!

See our installation instructions for the Homebrew method.

Install Radicle on Windows with WSL

This installation method isn't officially supported by the Radicle team, but you can try it at your own risk!


Our thanks go to the folks behind radicle-jetbrains-plugin, who first discovered this method of installing rad on WSL and Windows.

Assuming you already have WSL installed, follow the Debian/Ubuntu instructions on our get started guide.

Check what version of Git your WSL installation has with git --version. If it's lower than 2.34.0, you need to update, and if you're using the WSL default Ubuntu 20.04 you can add the git-core PPA to your system to supply a newer version of Git.

sudo add-apt-repository ppa:git-core/ppa
sudo apt update
sudo apt install git

With the appropriate version of Git installed, run rad auth to create your identity.

But to properly load and manage your identity's keys, you need an SSH agent. Install keychain with sudo apt install keychain, then open your ~/.bashrc file. Add the following two lines:

eval `keychain --quiet --eval --agents ssh`;

Save the file, exit WSL, and relaunch.

You can now navigate to an existing Git repository and run rad init to create a new Radicle project, or clone an existing project with rad clone.
