I am getting a similar error: MTXrun | unknown script 'context.lua' or 'mtx-context.lua' upon a fresh install of context. -- mtxrun https://bugs.launchpad.net/bugs/379146 You received this bug notification because you are a member of ConTeXt distribution team, which is the registrant for ConTeXt distribution. Status in ConTeXt distribution: New Bug description: from Alan BRASLAU, untested I did a fresh install of the minimals today and observed a fleeting, obscure mtxrun bug: $ context myfile did not find the script mtx-context.lua $ mtxrun --script /usr/local/context/tex/texmf-context/\ scripts/context/lua/mtx-context.lua myfile ran fine, as now does all subsequent runs of "context myfile". So something gets initialized, but is not found by default. You will only notice this upon a (totally) fresh install.
