How to Double Check I am on Most Stable System?

Support
1

Hi guys, I just installed from the minimal ISO, KDE Plasma. (my first post here KDE, Stability of Manjaro)

I am on Manjaro KDE. I want to doublecheck and be sure I am on the most stable repos, no AUR, no backports. Only stable. How can I check that?

Any suggestions to get the most stable system? I do not really care that much about “bleeding edge” software. Stability is my top Priority, then responsiveness and resource use (especially RAM).

How can I check I am on the most stable?
I think as well better to install and use LTS kernel, but I do not want to take the rsik and try doing it on my own (there is Grub stuff included I am sure). How best to install LTS Kernel, make it default and update Grub?

Hi @oldtux,

Stable is the most, well, stable branch, and also the default in use on thee ISO. Nevertheless, if you want to confirm, you can use:

pacman-mirrors --get-branch

For example:

$ pacman-mirrors --get-branch
stable

Edit:

Kernels can be managed from the CLI using mhwd-kernel. There’s also a GUI that I don’t use. Best would be to see:

Thanks @Mirdarthos for the prompt reply.
Amazing Manjaro and community.
I got pacman-mirrors --get-branch  ✔ stable So I am fine.
Would it be better to install and use LTS Kernel or better stay with the default? How to do that?

That depends. LTS is good, I use it mysself, but the others are there if you need one for a specific reason.

Done!
Thank you @Mirdarthos
I installed the latest LTS Kernel, took the risk and played with Grub (I have a grub menu now).
I also searched the forum and doublechecked How to make a Kernel default? - #3 by linux-aarhus

Now:

 uname -a                                                                                       ✔

The following kernels are installed in your system:

   * linux69
    ~  pacman-mirrors --get-branch                                                                    ✔ 
stable
    ~ 

I think it is OK now I am on the latest LTS kernel, on stable repos.
I double checke as well that AUR is disabled!

So my system is the most possible stable system.

Thank you all for your support and for Manjaro!

Sorry @Mirdarthos to bother you again.
I installed the LTS kernel, but I have been reading allover the forum to find a way to make it the default kernel to boot to while keeping the latest kernel (just in case), but I couldn;t find a way to make the LTS kernel the default one to always boot to while the latest kernel is still installed.

I found
Continuing the discussion from How to make default kernel:

So this till now seems to be the only way.
I mainly care about running the LTS as it is supposed to be more stable.

Is it safe to really delete the latest kernel?
Is it OK to do it?

Edit:
I just thought of installing an older LTS (or non LTS) kernel, just in case. What you think?

Considering you don’t care about or need to have the latestt-and greatest, I would suggest the folllowing:

  1. Have the latest LTS installed, 6.6 in your case:

    sudo mhwd-kernel --install linux66

  2. It is generally advised to have two kernels installed, so that if you encounter a problem with thee other one, you have the “older”/other one to fall back on. So let’s us say in this regard it’s version 6.1:

    sudo mhwd-kernel --install linux61

  3. Make sure only those t wo kernels are installed. Check which are installed with:

    sudo mhwd-kernel --listinstalled

  4. Uninstall those identified with:

    sudo mhwd-kernel --remove <identifiedKernel>

    Where <identifiedKernel> is the kernel version identifies in the prior step.
    For example:

    sudo mhwd-kernel --remove linux515

Hope this answers your question.

Thank you @Mirdarthos
You just confirmed what I was thinking. It is better to have another kernel.
So, I will install a kernel older than the LTS and keep the LTS to be the latest.
Thank you

Just make sure the older kernel is still supported and not EOL already. 6.1 is a good bet, seeing as it will be maintained for 10 years!

WOW! 10 years! I might not be around then. LOL
I just did and took your advice.

 mhwd-kernel -li                                                                                ✔

Thank you very much for your kind support and attention.
Now I will start really enjoying my Manjaro.

Sorry. The solution was supposed to be How to Double Check I am on Most Stable System? - #2 by Mirdarthos
I wrongly selected my own post while it is supposed to be @Mirdarthos post.
How can I correct this?

I hope a moderator can fix this error I made.
