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. – user535733 Dec 10 '17 at 15:50

    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. – Eliah Kagan Dec 11 '17 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. – Nermeen Hussein Dec 11 '17 at 8:59

    +1. One small thing, you might need to enable restricted repo first to install/update intel-microcode. – pomsky Dec 12 '17 at 13:22

    @NermeenHussein It might already be enabled. If not, you can open "Software & Updates" and enable it. – pomsky Dec 12 '17 at 13:29
