Installing rust on older linux systems

Posted by Simon Walker on Wed 15 June 2016

At work we use SLES 11 which has quite old versions of openssl and installed certificates. I was getting certificate errors trying to install rust with the rustup tool.

I tried searching for any help at all but in the end I followed the following advice:

  • download a more recent certificate bundle (e.g. from certifi or mozilla)
  • set the environment variable SSL_CERT_FILE to point to this new file

This works for both rustup and cargo meaning I can develop with rust on my work machine.
