Problem Description:
I currently have 6.8.0-90 kernel installed and trying to find the correct canonical ppa to use to keep the kernel updated or install a certain canonical kernel version for 6.8. I have some backup software that only supports certain kernel versions for Ubuntu. I have tried to install the 6.14 HWE kernel but system fails to boot with that kernel.
Most support articles I have found refer to mainline kernels and unable to use those. I am also fairly new to Linux and Ubuntu as well, so please be gentle.
90 is the latest version for the 6.8 kernel.You don’t need a ppa for kernel updates,it’ll update when a new version is available through a regular system update/upgrade.
As far as mainline kernels go that’s not something you want to do as they are not supported and will not receive security updates.
These kernels are not supported and are not appropriate for production use. Additionally, these kernels do not receive any security updates, therefore if you install them manually via the Mainline PPA, you will never receive a security update or patch for that version.
Thanks. I just wanted to make sure I didn’t have to do anything different. I definitely don’t want to use mainline kernels. If they say I need a certain version of kernel for their software to function, is there a way to install and older canonical kernel from the official channels?
Don’t add any new source or PPA. Everything you need is in sources that you already have.
You can try specifying to apt the specific kernel version you want Example: sudo apt install linux-image-6.8.0-45-generic
If that fails, you can download the kernel package deb manually (use a web browser at archive.ubuntu.com) and install it sudo apt install ./path/to/the/downloaded/package.deb
Then you must reboot, selecting the correct kernel at GRUB.
Those are the basics. A lot could go wrong, since we don’t know why your hardware doesn’t boot (that’s usually a serious bug!) or your picky backup software (that’s unusual and curious), or your actual level of skill with Linux.
Warning: Since your hardware and software are curiously kernel-specific, your system may break if you release-upgrade to Ubuntu 24.04 or (future) 26.04. There are other pitfalls, too.
As a new user, we usually don’t recommend diving deep into kernel arcana and certainly not PPAs. On a properly-functioning system, the default kernel should Just Work with almost all hardware and software. So you are already well off the marked trail and wandering deeper into the thickets. We wish you good fortune in your travels.
What backup software is this and what exact kernel version does it want? For 22.04 you have the option of the 5.15 GA or the 6.8 HWE kernel. Anything else is unsupported on that series. You want to use a supported kernel or you’re missing out on security fixes.
Hello Norm24 - I am a new user to this… you helped another member. Can you private message me? I feel like I need a dedicated chaperone to making a new post, unfortunately. I feel dumb and can’t figure this site out.
Hello and welcome to Ubuntu Discourse trc-subscritions you should have received a message when you registered telling you exactly what you needed to do to be able to post in the support and help category.
You only need to read five minutes to post in the support and help category.
Please do not ask for support via a private message, we give open support so everyone can benefit from the support and not just one person.
Please let a moderator know via a private message if you are still having trouble posting in the support and help category after reading five minutes and giving the servers a few minutes to catch up.
I think my registration was a few years ago… anyway,
I did read the the stuff - and navigated for a LONG TIME…
I had an email inviting me to make a post - which eventually showed up. A simple “grayed out” feature would be sufficient to communicate the challenge
