My system is being affected as well, I'm running Ubuntu 16.04.4 having the same service failing to start.
There are a few reports of this on stackexchange as well with one particular solution about patching the kernel: https://unix.stackexchange.com/questions/308801/ureadahead-error-while- tracing-possible-kernel-patch-problem. I've also filed a bug with kernel.org : https://bugzilla.kernel.org/show_bug.cgi?id=199861 Running ureadahead with strace directly from terminal yields: # strace ureadahead --verbose --force-trace / [..] openat(3, "events/fs/do_sys_open/enable", O_RDWR) = -1 ENOENT (No such file or directory) close(3) = 0 write(2, "ureadahead: Error while tracing:"..., 59ureadahead: Error while tracing: No such file or directory [..] and "/sys/kernel/debug/tracing/events/fs/do_sys_open/enable" does not exist. ** Bug watch added: Linux Kernel Bug Tracker #199861 https://bugzilla.kernel.org/show_bug.cgi?id=199861 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1763584 Title: ureadahead service fails with error Error while tracing: No such file or directory To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ureadahead/+bug/1763584/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
