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 Touch seeded packages, which is subscribed to ureadahead in Ubuntu. https://bugs.launchpad.net/bugs/1763584 Title: ureadahead service fails with error Error while tracing: No such file or directory Status in ureadahead package in Ubuntu: Confirmed Bug description: I'm reporting this as duplicate of #1176536 to provide more info. dmig@dmig-Inspiron-5379:~$ systemctl status ureadahead.service ● ureadahead.service - Read required files in advance Loaded: loaded (/lib/systemd/system/ureadahead.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Fri 2018-04-13 13:09:41 +07; 10min ago Main PID: 379 (code=exited, status=5) Apr 13 13:09:41 dmig-Inspiron-5379 ureadahead[379]: ureadahead: Error while tracing: No such file or directory Apr 13 13:09:41 dmig-Inspiron-5379 ureadahead[379]: Counted 8 CPUs ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: ureadahead 0.100.0-20 Uname: Linux 4.16.2-041602-generic x86_64 ApportVersion: 2.20.9-0ubuntu4 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Fri Apr 13 13:13:26 2018 InstallationDate: Installed on 2018-03-27 (16 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Alpha amd64 (20180327) SourcePackage: ureadahead UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ureadahead/+bug/1763584/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
