    Post How to disable kernel upgrade, "take control" of kernel upgrading

    Hello,

    for a while now i've been working at disabling kernel upgrade for this fedora 29 system.

    so far, one of the things i've attempted is editing:

    /etc/yum.conf & /etc/dnf/dnf.conf and set installonly_limit to 2.

    this doesn't seem to have done the job.

    the goal is to take full control of the kernel upgrading task. find one that's stable for the machines and slow down the upgrading process.

    from personal experience, kernel upgrading occasionally breaks computer functionality.

    i'd like to slow down the process.

    Thanks,
    Hat tip

    Re: How to disable kernel upgrade, "take control" of kernel upgrading

    The setting you changed controls the number of old kernels you keep, essentially. I think what you're trying to do is stop kernel upgrades. This can be accomplished by editing the appropriate repo file and adding "exclude=kernel*" in the [base] section and also in the [updates] section.

    In my (CentOS) instance, the file is /etc/yum.repos.d/CentOS-Base.repo - yours will of course will be named appropriately for dnf and for Fedora, if I guess correctly.

    I hope this is helpful. I was forced to do this on one machine because of hardware - I am nervous about what's going to happen when some update for something else installs that depends on a newer kernel than I have ...

    Remember - importing/building packages will likely "byte you in the butt" come update/upgrade time, long after you'd forgotten you did that! Use repos whenever possible.

    Adding "exclude=kernel*" to your /etc/dnf/dnf.conf file will accomplish what you want, as that applies to all enabled repos.
