emerge and linux-headers - masked

[luizferp]

Hi people,

Some days ago I upgraded a very out-of-date gentoo instalation and since then I'm having some annoying problems. Every time I do an emerge sync I have to unmask the >=sys-kernel/linux-headers-2.6 line at /usr/portage/profile/package.mask.

If I don't do this, I get the message:

Code: Select all

Calculating world dependencies -
!!! All ebuilds that could satisfy "sys-kernel/linux-headers" have been masked.
!!! One of the following masked packages is required to complete your request:
- sys-kernel/linux-headers-2.6.8.1-r4 (masked by: package.mask)
# <johnm@gentoo.org> (1/12/2004)
# Masking all 2.6 versions of kernel packages which were originally

For more information, see MASKED PACKAGES section in the emerge man page or
section 2.2 "Software Availability" in the Gentoo Handbook.
!!!    (dependency required by "sys-apps/util-linux-2.12i-r1" [ebuild])


!!! Problem with ebuild sys-apps/man-pages-2.01
!!! Possibly a DEPEND/*DEPEND problem.

!!! Depgraph creation failed.

I've seen that the problem seems to be related to man-pages or util-linux but I'm not sure how to solve it.

Even if I do an emerge -p depclean I get the same error.

Does anybody knows what is happening, why I always have to unmask the linux-headers and, of course, how I solve it?

Thanks in advance.

Hrm...did you update the system profile during the upgrade? /etc/make.profile should point to something like /usr/portage/profiles/default-linux/x86/2004.3

Yes, I updated the system profile right after upgrading portage!

The /etc/make.profile was pointing to /usr/portage/profiles/default-linux/x86/2005.0 and when I changed to /usr/portage/profiles/default-linux/x86/2004.3, the dependency problem disapeared but now the emerge attempts to downgrade the linux-headers to 2.4.22 (now it's 2.6.8.1-r4).

Can I have problems with the downgrading of the linux-headers?

Aha...to install headers for the 2.6 kernel, you need to use the package 'linux26-headers', not 'linux-headers.'

Mm. I don't think sol.

Code: Select all

# ls /usr/portage/sys-kernel/linux-headers
ChangeLog                       linux-headers-2.4.23.ebuild

Anyway. If you link /etc/make.profile to /usr/portage/profiles/default-linux/x86/2005.0 "emerge -uD world" want wo merge linux-headers, which are all masked. (by keyword or package.mask)

Nonetheless, it is true:

Code: Select all

Code Listing 11.1: Updating to linux26-headers
# emerge --unmerge linux-headers
# emerge linux26-headers

Yup...which is why you use the unmasked linux26-headers package.

It is a bit confusing. The category sys-kernel/linux-headers now contains the stable 2.4-linux-headers and the unstable(hardmasked) linux26-headers, besides the antique 2.2 and 2.0 headers. The category sys-kernel/linux26-headers contains the stable 2.6-headers.

This is of course not logical, at least to me. Either one category has the stable headers and the other ths unstable headers, or there should be categorys for >=2.4 and for 2.6, with each one containing unstable versions, keyworded and/or hardmasked.

Maybe it is a bug, since there are seemingly not that many devs, who update the headers accordingly to the kernel-releases. They mainly concentrate on bugfixing, and that is obviously just fine.

AFAIK There is a transition going on to move the linux26-headers back to the linux-headers package. This is work in progress and therefore they are still masked there. The same probably holds for the 2005.0 profile. I did not see an announcement that it is released.

Sounds reasonable. Otherwise Gentoo would probably end up with linux26-, linux2.8 and linux3.(2*n)-headers. Thanks for this information.
