I saw several bugs and error messages when I was looking by chance into the tool called "logs".

Being a newbie in Ubuntu I have no idea how to deal with these bugs, where to report them or how to fix them. Any help to guide me here?

The bug I have (which is listed under important) reads:

[Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0x52 (or later)

  • Search AskUbuntu for the key text related to each bug. All have probably been asked and answered already. Example: The 'DEADLINE' notification is not a bug at all - it's notifying you to take an action.

    Assuming this is just an example and you really are looking for information on how to report bugs, rather than for how to solve that particular problem, see How do I report a bug? As for this specific problem, I believe N0rbert's solution should help you. Dec 11, 2017 at 2:07

Just install intel-microcode with sudo apt-get install intel-microcode and reboot.

If it does not help, try to update your BIOS.

It was already reported to launchpad as bug 1724650.

  • I tried your first suggestion and now this bug is gone from my log :-) There are still other things of course, so I'll try to look around and see how they can be fixed. Thanks a lot. Dec 11, 2017 at 8:59

    +1. One small thing, you might need to enable restricted repo first to install/update intel-microcode.

    @NermeenHussein It might already be enabled. If not, you can open "Software & Updates" and enable it.
