Solana: 403 error when installing solana cli

If you are trying to run the following:

sh -c "$(curl -sSfL"

and are getting an error like:

curl: (22) The requested URL returned error: 403
solana-install-init: command failed: downloader /tmp/tmp.wa8sM5bWar/solana-install-init

Here’s an example:

tar jxf solana-release-x86_64-unknown-linux-gnu.tar.bz2
cd solana-release/
export PATH=$PWD/bin:$PATH

The tar jxf line assumes you have already downloaded the .bz2 file. You should select and download the appropriate binary the releases page at
