The instructions linked to above tell you to upgrade kernel-headers - I thought you were supposed to leave that one alone?

So I shouldn't use those instructions?
Using slpkg I could just run the following then couldn't I?

Code: Select all

# slpkg -u slack kernel-huge-4.4.3-x86_64-1.txz --upgradepkg

No, the instructions are absolutely fine, I just don't think you should be upgrading the kernel-headers package (if it is even installed on your system, which you can see by following the instructions). I suggest you leave it out for the time being, and check back here for an authoritative verdict on that point.

My understanding is that the kernel-headers are needed for compiling things, and need to be the same ones that were used to build the C libraries installed in your system. You don't want to upgrade those, because then you would have to recompile all the packages that use them. Therefore, kernel-headers should only be upgraded in the rather different scenario that you are upgrading from one Salix version to the next, and switching repositories accordingly.

Perhaps someone can confirm or correct that?

Don't upgrade the kernel-headers package.

Don't upgrade the kernel-headers package.

OK, and after I install the kernel packages, do I do a

Code: Select all

$ cd /boot
$ sudo cp vmlinuz /boot/efi/EFI/Salix/

or should I use mv?

[gapan]

Yes.

[globetrotterdk]

OK. The kernel upgrade appears to have gone fine, but unfortunately I am still having problems with the wifi connection

Did you try the other options from the link posted by laprjns?

Hmmm. Interesting. I rebooted after installing the new kernel and the wifi problem was still there. I shutdown the laptop and went into town. I just got back and now everything seems to be working after I started the computer again. I am streaming video, updating slapt-get and spi, all at the same time. It seems to be working correctly now, but I will wait a couple of days before I mark this thread as solved, just in case. Thanks to everyone for the help.

If you do still have trouble, it may be worth trying a somewhat earlier kernel. Because of this thread, I thought I'd upgrade to 4.4.3, and my own wireless stopped working (I'm using a spare dongle for now). Previously, I had the kernel gapan uploaded to the forum last summer, which worked fine with it. So in my case, it looks like a regression.
