I can't run the test program:

andromeda1# bin/lkp run ./job-300s-256G-msync.yaml
grep: /root/lkp-tests/hosts/andromeda.procyon.org.uk: No such file or directory
/root/lkp-tests/bin/run-local:121:in `<main>': undefined method `chomp' for nil:NilClass (NoMethodError)

job['memory'] ||= `grep -w '^memory:' #{LKP_SRC}/hosts/#{HOSTNAME}`.split(' ')[1].chomp
                                                                                 ^^^^^^
