  • Can't give you a categorical answer based on what I've seen so far - but what does:

    apt-get dist-upgrade -u

    say it's going to do? (It will give you a chance to hit 'n' and abort the upgrade).

    Sometimes packages are held back because apt-get upgrade is conservative about how aggressively it will change your system.

  • Hi again, Vivek. Thanks for your help! 

    apt-get dist-upgrade -u won't give me the option to install the three held packages. If I try to update them through Synaptic y can do it but I would uninstall the following packages that I suppose they are important for the video card:

    libegl1-mesa:i386, libgbm1:i386, libgtk-3-0:i386, libwayland-client0:i386,libwayland-cursor0:i386,libwayland-egl1-mesa:i386

     

    Would they be safe to uninstall?

  • Those are the i386 (32 bit) libraries for running 32 bit executables - It's possible you'll need them to run a proprietary 3rd party application or game, but otherwise they're not that important. If you check the policy for them on both architectures like so:

    apt-cache policy libegl1-mesa:i386 libegl1-mesa:amd64

    does it look like matching packages for both arches are available?

  • Maybe when I installed steam for linux...

    This is what I get with 

    $ apt-cache policy libegl1-mesa:i386 libegl1-mesa:amd64
    
    libegl1-mesa:i386:

    They look pretty the same to me...

  • It seems they were installed with pipelight:

    $sudo aptitude why libgtk-3-0:i386
    
    i   pipelight-multi        Depende     wine-staging                             
    
    i A wine-staging           Depende     wine-staging-i386 (= 1.9.7~ubuntu16.04.1)
    
    i A wine-staging-i386:i386 Proporciona wine-staging-i386

  • Ok. You're right, the i386 and amd64 versions look the same, and there is something that requires them - note that they come from a PPA and not the 01.org repo, which is probably why they are being held - the PPA repo has different versions to the 01.org repo.

    As long as you have a working system (ie you're not seeing any problems as a result of these) then I'd be inclined to leave them alone.

  • I'll do that and report if I find any further problems. Thanks for your help, Vivek!

  • Hi,

    I'm having a similar problem while running the Intel Graphics Update Tool on a fresh 16.10 Yakkety install. When I run the tool, it fails while upgrading system, with the following message:

    W:GPG error: https://download.01.org/gfx/ubuntu/16.10/main yakketyInRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 611B903CAB97EA77, E:The repository 'https://download.01.org/gfx/ubuntu/16.10/main yakketyInRelease' is not signed.

     

    Any steps I can take to fix this? Current performance is sluggish (for instance when dragging/resizing windows) and I'm hoping to fix that with a newer driver.

  • The instructions here https://01.org/linuxgraphics/downloads/intel-graphics-update-tool-linux-os-v2.0.3 should let you add the 01.org linux graphics signing key to your system so that the signature can be recognised (you should of course satisfy yourself that the key is trustworthy).

    As to ths sluggishness - the ubuntu 16.10 release is already up to date with respect to the kernel, so the update tool won't change the kernel's i915 driver. If you're experiencing sluggishness, I'd check a few things:

    Is the i915 driver in use? (lspci -kvnn and check the "kernel driber in use" line for the graphics adapter section)

    Is the machine coming up fully acellerated, or has it fallen back to framebuffer mode? (check th eoutput of dmesg and the Xorg.0.log or similar in /var/log).

    Those should give you some clues if something is going wrong.

  • I meant to write "Kernel driver in use", of course.
