Hi Radek,

Which version of leth are you running at the minute? which OS are you using?

If you run leth version it should produce the following output:

$> leth version
Version: 0.9.0-alpha Sirius

if not, please download the latest version indicated in the install steps


Hi, I’m on macos, yes I followed the install steps and installed the latest binaries. leth is at version 0.9.0-alpha Sirius


Hey Radek,

We added tags to the repository and re-uploaded the binaries. Try again please and sorry for the inconvenience.

/usr/local/bin/lightchain version
Version: 0.12.0-alpha Gas Price

/usr/local/bin/leth version
Version: 0.9.1-alpha Sirius
