 Posted: Sat Mar 16, 2024 1:40 am Post subject: [SOLVED] Surprise dependency installed kernel 6.6.16! |
 |
|
Hello,
Yesterday I updated my system as usual and among the packages that needed to be updated was the linux firmware. So, after the update I did the kernel and module rebuild using the commands below:
| Code: |
cd /usr/src/linux
make modules_prepare && make && emerge @module-rebuild && make modules_install && make install && make clean
dracut --force --kver=6.1.74-gentoo
grub-mkconfig -o /boot/grub/grub.cfg
reboot
|
Instead of booting to 6.1.74, it booted to 6.6.16! I never installed this thing! I did some digging to figure out where this thing came from and found out the following:
| Code: |
emerge -av --depclean gentoo-kernel:6.6.16
Calculating dependencies... done!
sys-kernel/gentoo-kernel-6.6.16 pulled in by:
virtual/dist-kernel-6.6.16 requires ~sys-kernel/gentoo-kernel-6.6.16
virtual/linux-sources-3-r8 requires sys-kernel/gentoo-kernel
equery d linux-sources
* These packages depend on linux-sources:
x11-drivers/nvidia-drivers-535.161.07 (modules ? virtual/linux-sources)
equery d dist-kernel
* These packages depend on dist-kernel:
sys-kernel/gentoo-kernel-6.6.16 (>=virtual/dist-kernel-6.6.16)
x11-drivers/nvidia-drivers-535.161.07 (dist-kernel ? virtual/dist-kernel)
|
Why is the nvidia drivers all of sudden needing to install gentoo-kernel-dist? How do I get rid of this mess?
Thanks,

Did you manually unmerge your old kernel at some point?

nvidia-drivers depends on linux-sources.
linux-sources has | part of RDEPEND: | || (
sys-kernel/gentoo-sources
sys-kernel/vanilla-sources
sys-kernel/git-sources
sys-kernel/mips-sources
sys-kernel/pf-sources
sys-kernel/rt-sources
sys-kernel/zen-sources
sys-kernel/raspberrypi-sources
sys-kernel/gentoo-kernel
sys-kernel/gentoo-kernel-bin
sys-kernel/vanilla-kernel
sys-kernel/linux-next
sys-kernel/asahi-sources
) |
... so no, gentoo-kernel isn't required, but it's one choice among all the others.
Portage might pull in any of those if you don't have any installed.
Hence the question logrusx posted.

Not sure what you mean by manually, but I followed this guide (https://wiki.gentoo.org/wiki/Kernel/Removal).

How can portage pull in gentoo-kernel if I'm logged in using gentoo-sources (6.1.74-gentoo)?! I don't use that package and never have. The guide I followed from the wiki to remove gentoo-kernel is not working, so is there a different way of doing this?

It doesn't matter what you're suing, you may very well be using a kernel built from sources manually downloaded from kernel.org. Portage has no knowledge of that, it only understands packages.
If at the point or upgrade of nvidia drivers you didn't have a kernel *package* installed, emerge would chose one of the list above. However I doubt it would exactly pick gentoo-kernel if there wasn't something else in the equation.
Maybe if you go to /var/log/emerge.log and post that part which includes the update process we could get more information to solve this mystery. I expect the whole file might be a bit too large to share on the popular paste sharing sites.
Best Regards,

I hope I'm right about this because I believe I found the root cause of this mess.
A few weeks ago, there was a gentoo-sources update to 6.6.13 and so I did the necessary steps to update. When I rebooted, all USB devices stopped working. So, I opened a thread and consequently, a bug report. I tried fiddling with the kconfig and got tired of building and rebooting plus NVIDIA didn't either, so I switched back to 6.1.67.
There seems to be a patch but it didn't solve the problem because a few users reported the same issue related to USB devices and NVIDIA not working. To avoid portage updating to 6.6.*, I masked any version above 6.1.67 and I accidentally found that 6.1.67 was mysteriously dropped from the list of available gentoo-sources. I updated to 6.1.74 and masked any version above that one as well. Running 'eix -I gentoo-sources' displays a question mark next to it, so I ran 'eix-update' to fix it. When that didn't work, I checked the available versions on the packages website and it turns out 6.1.74 is in an unknown state for AMD64 and that explains why gentoo-kernel was installed.
It would be really helpful if emerge can check the currently installed version against the ones on packages.gentoo.org and display an alert ("the currently installed kernel is no longer supported, please update to a supported version") or whatever helps avoid problems like these.
I was able to remove gentoo-kernel and dist-kernel using 'emerge --unmerge' command. I am now building gentoo-sources-6.1.81 and hopefully things become stable again.

Generally, in situations like that where multiple choices are available to satisfy a dependency, if you're not happy with what portage selects, you can emerge a different one prior to updating, so that portage is happy and don't select for you. That usually would be a --oneshot merge.
If you're already in such a situation, you emerge what you want and then unmerge what was selected by portage. This way the dependency graph would still be consistent. That again would usually be a --oneshot merge.
p.s. you can now edint the first post and add SOLVED to the title.
Best Regards,
Georgi |

I suspect you did the mask incorrectly. If you don't want to move above 6.1.x, then the safe and forward-compatible mask would be >=sys-kernel/gentoo-sources-6.2. This will allow all future 6.1.x updates as they arrive, but refuse all 6.2.x and later (so also 6.3.x, 6.4.x, ...). | myga wrote: | | I accidentally found that 6.1.67 was mysteriously dropped from the list of available gentoo-sources. |
This is normal. In almost all cases, when a new stable kernel is released, it will include the statement that All users must upgrade. As such, older kernels in that line get removed, because users should not be using them anymore.

I find this doubtful as an explanation. Portage does not look at the packages website. The website should not be showing "Unknown" for a major architecture. Do you have a link to where this can be seen? | myga wrote: | | It would be really helpful if emerge can check the currently installed version against the ones on packages.gentoo.org and display an alert ("the currently installed kernel is no longer supported, please update to a supported version") or whatever helps avoid problems like these. |
Portage does check that your currently installed sources are still the most current among the selected sources. Portage cannot in general rely on contacting packages.gentoo.org, nor should it even if that were possible. |

That makes sense but at the time I relied on what on the packages page to avoid any more issues.

A detailed message would be nice tho.

Here is the grid (https://packages.gentoo.org/packages/sys-kernel/gentoo-sources) go to 6.1.74 x AMD64.

Not the way I'd like to see it, but I'll create my own script to deal with this in the future.
