This is not quite accurate. All autobuilders except the x32 one work. And only of of the two amd64 autobuilders for the reproducable build work, the other fail due to missing perf access. The new message explain the problem quite nicely. I suggest we close this bug as fixed with the new message, as we can not really "fix" coz to work without the kernel feature it require to do the profiling. The message look like this (from the second reproducable build on amd64): Failed to open perf event. Consider tweaking /proc/sys/kernel/perf_event_paranoid to 2 or less (current value is 3), or run coz as a privileged user (with CAP_SYS_ADMIN). I guess it could be made clearer, but it contain enough to google up an explanation about what is going wrong. I found <URL: https://lkml.org/lkml/2016/7/27/305 > providing some background information about the value 3. Apparently is block "all access to performance events by users without CAP_SYS_ADMIN", and is the default in Debian and Android. -- Happy hacking Petter Reinholdtsen
