please run revdep-rebuild first.

This most certainly isn't a bug. Emerge app-portage/gentoolkit and run revdep-rebuild. If you need support, find the #gentoo channel on the Freenode network or visit <http://forums.gentoo.org/>.

try a revdep-rebuild -X, it will take latest versions available of each packages which should avoid the failure you are seeing.

[Comment 7 Gilles Dartiguelongue (RETIRED) 2008-08-11 13:49:49 UTC]

fixing product.

[Comment 8 vairam 2008-08-12 10:01:37 UTC]

Same Error coming after restarting the apache2

I have run the below command also

revdep-rebuild -X

We cannot really do much for you until you start providing us with the information we need to assess what is really wrong with your system. Specifically, you haven't provided any information from which we might learn that revdep-rebuild ran successfully, or what packages it rebuilt. Please also post your `emerge --info'.

and what happens when you run:

emerge --oneshot sys-devel/gettext dev-libs/apr-util dev-perl/DBD-mysql net-fs/samba www-servers/apache

this is what revdep-rebuild -X should do (assuming you only have 1 apr-util version installed, if not, please tell portage which version of apr-util to reemerge).

apr-util-0.9 and friends are long dead, you should upgrade a bit more often :)

Pretty clear. A very outdated system. Bad maintenance, PEBKAC issue.


vairam: You have to update your system more often. This isn't a distro based on a snapshot and further binary package updates you can - vulnerability fixes aside - install and forget. Please use our user channels like the forums or the gentoo-user mailing list, after reading the available system management documentation¹ This isn't a bug at all, but shows lack of understanding how to administer Gentoo systems.
