Error: quartus_map ended unexpectedly

Thanks for the answer, I did the echo... it was just that it didn't help, so I thought I haven't understood, or had missed something. It seems I have already solved it by adding release information to the file /etc/arch-release, which is void for kind of arch philosophical reasons, and I don't get why, but quartus seems to need it. Have you had any other problem with quartus so far?. I'm in my way to install modelsim and nios and I'm the only guy who went nuts and installed arch when everyone else uses fedora (tought I guess it'll pay in the end). Thanks!.
