    Weaning off of Update Manager in favor of apt-get

    New to Ubuntu. Experienced with CentOS and yum. I have 12.04 LTS Desktop 64-bit for now and I'm trying to wean myself off of all the GUIs so that I can make a move to Server so as to boost my VM capabilities.

    Question: How can I tell from the CLI whether a Kernel update is available? The GUI Update Manager says I'm due for a kernel update (3.2.0.29.31 -> 3.2.0.34.37). But 'sudo apt-get -s upgrade' doesn't say the kernel would be upgraded. All it says is that linux-generic, linux-headers-generic, and linux-image-generic have been kept back. I've also tried 'sudo apt-get update', but it doesn't make any difference. I'm sure I'm missing the appropriate command here. If it weren't for Update Manager I wouldn't know that there are kernel updates available. How would I know? Thanks.

    I believe that "linux-generic" is actually the kernel package. When you see the "linux generic has been kept back" message, that usually means that a new version of the kernel is out. For reasons that I am unsure of, apt-get upgrade won't get the kernel updates by default. But
    Code:
    sudo apt-get dist-upgrade
    should install them for you.

    Hope this helps,

    Mr. Hibba

    Re: Weaning off of Update Manager in favor of apt-get

    if you install aptitude you can issue
    Code:
    sudo aptitude update && aptitude safe-upgrade
    and I believe that will upgrade your kernels OR if you want to stick with apt-get the command would be
    Code:
    sudo apt-get update && apt-get dist-upgrade

    Re: Weaning off of Update Manager in favor of apt-get

    Code:
    man apt-get
    great tool
    aptitude is a good tool too.
    general advice is to not mix usage of these two,
    pick one and stick with it.

    That particular problem was fixed a long time ago. Mix and match is fine.

    Re: Weaning off of Update Manager in favor of apt-get

    To make things a little quicker, I've added the following to my .bash_aliases file:

    Code:
    alias updatenow='sudo apt-get update && sudo apt-get dist-upgrade'
    So, how many of you have added the following to your .bash_aliases file:..?

    Code:
    alias exiy='exit'
    Fat finger can be such a pain.

    The reason is that apt-get update only replaces existing package versions with new ones.

    On the other hand, kernel updates don't replace the old kernel, but instead add the new one alongside the old version. And to do that you need apt-get dist-upgrade.

    Ah, thank you, that makes sense.

    We are using CentOS 5 in dev (RH in production) and mix and match YUM and apt-get with no issues to report.

    i'm still on 10.04.4 and I mix and match apt-get and aptitude all the time. It'll be fine
