OK, my efforts to correct the the damage to my gentoo functionality as a consequence of dealing with this problem left me with a borked system.

I no longer have sys-apps/util-linux on my system... :(

I'm now chrooted using gentoo min install cd and tried to emerge sys-apps/coreutils-6.10-r2, and have come up with:
Code:

[blocks B  ] <sys-apps/util-linux-2.13 (is blocking sys-apps/coreutils-6.10-r2)


Would someone please tell me a way to deal with this?

Thanks...


emerge --nodeps -v1 coreutils

This helped a lot... Thank you!

Now revdep-rebuild is free of blockers, but has rebuilt only a few, but not all packages...

Most packages fail with 'Temporary failure in name resolution' as exemplified when I attempt to emerge --sync:

Code:
Notice: (-3, 'Temporary failure in name resolution')
>>> Starting rsync with rsync://rsync.us.gentoo.org/gentoo-portage...
>>> Checking server timestamp ...
>>> Retrying...
Notice: (-3, 'Temporary failure in name resolution')


>>> Starting retry 1 of 3 with rsync://rsync.us.gentoo.org/gentoo-portage
>>> Checking server timestamp ...
>>> Retrying...
Notice: (-3, 'Temporary failure in name resolution')


What must I do to correct this?

Thanks!


hi!

i think this is due to a dns problem. you can wait a few hours and try it again or you can change your rsync server.
you can find the status off all rsync servers here:

http://mirrorstats.gentoo.org/rsync/

HTH
snIP3r[/code]

I don't believe it's related to the rsync server, because my desktop gentoo box, with the same settings, is able to sync without problem. Somehow, it's because I'm in a chrooted environment, and multiple files, including I think my world file<, been disrupted by what started to be a blocker and mit-krb5 problem 2 days ago. :(

Can anyone help with this? Please??

check you can ping www.google.co.uk from your chrooted env.... if not check your /etc/resolv.conf for the correct settings.

unmerge util-linux and emerge coreutils :-)


I'm thinking re-emerging baselayout may alleviate some of my persisting problems. However, I get the following:
Code:

 # emerge -av baselayout

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild     U ] sys-apps/coreutils-6.10-r2 [6.9-r1] USE="acl nls (-selinux) -static -vanilla% -xattr" 0 kB
[ebuild   R   ] sys-apps/baselayout-1.12.11.1  USE="unicode -bootstrap -build -static" 0 kB
[blocks B     ] <sys-apps/util-linux-2.13 (is blocking sys-apps/coreutils-6.10-r2)



When I attempt to follow richard.scott's advice about unmerging util-linux I get the following ominous warning:
Code:

# emerge -aC util-linux

>>> These are the packages that would be unmerged:


!!! 'sys-apps/util-linux' is part of your system profile.
!!! Unmerging it may be damaging to your system.


 sys-apps/util-linux
    selected: 2.12r-r8
   protected: none
     omitted: none


Is this something I can safely do??? :?

Would someone please advise me about this...

Thanks!

While trying to implement:
Code:
# echo "<=app-crypt/mit-krb5-1.6.3-r2" >> /etc/portage/package.keywords
# emerge -f e2fsprogs e2fsprogs-libs
# emerge --unmerge ss com_err e2fsprogs
# emerge e2fsprogs

...As soon as I run # emerge --unmerge ss com_err e2fsprogs, I lose emerge function, getting the following:
Code:

# emerge e2fsprogs
sudo: error while loading shared libraries: libcom_err.so.2: cannot open shared object file: No such file or directory



What could be causing this? I now can't emerge anything... :(

when you unmerge com_err, it breaks emerge.

there are lots of fixes, research one and find one you think works.

BTW, when I did this, and then had someone turn of the machine, I couldn't boot either, so don't reboot until you get a fully emerged system.

Thank you for that information!

OK, I've finally fumbled into a bootable system, but I'm still confused about one issue...

What version of app-crypt/mit-krb5 should I have running? In spite of following the advice of richard.scott, and doing:
Code:
# echo "<=app-crypt/mit-krb5-1.6.3-r2" >> /etc/portage/package.keywords


I've ended up running a masked version (I have no idea how):

Code:
 equery list mit-krb5         
[ Searching for package 'mit-krb5' in all categories among: ]
 * installed packages
[I--] [M ] app-crypt/mit-krb5-1.6.3-r4 (0)


Should I unmask that version and stick with it, or should I upgrade to a newer version? :?

Do you, or does anyone, have advice about the best version?

Thanks!

It depends on what kind of system that you have to say that it is masked. Look here here it will show that app-crypt/mit-krb5-1.6.3-r4 isn't masked on all systems.

I ran emerge --sync and the mask disappeared... :D

Just ignore the mit-krb5 stuff then :D

you still have to resolve the blockers as ss and com_err seem to be being replaced by e2fsprogs

snIP3r is talking about the mit-krb5 being marked stable. The required version of mit-krb5 is now available in the default portage tree without unmasking it.

Everyone else will ALWAYS have these ss/com_err blockers that you will need to resolve.

All servers I manage have had this blocking issue :lol:

thanks for that Richard,

I'm still wondering how this is to get sorted out. I've read several threads on it and (haven't looked yet today) it doesn't appear there is an agreed upon method. Masking the new efsprogs seems safest but then that is only a temporary thing that will require more intervention later.

The unmerge the blockers technique makes me hesitate after reading of the broken machines resulting from doing that. I could mess with fetching the files first, but I'm thinking that isn't the way to treat the "safe" arch users or the newbs. So I'm watching..

cheers, JD

I manage 10+ servers (well 11 really :wink: ) and I've had this blocker happen on them all.

As long as you remember to "-f" the files before you unmerge anything you should be pretty safe.
From what I've seen most errors are due to the unmerge breaking wget as it needs SSL which needs COM_ERR/SS etc.
If you've already downloaded the required files then portage won't need to run wget.

You could always create a "quickpkg" using a script from gentoolkit and then just re-emerge the binary package from your local filesystem if things do go wrong.

Perhaps if you wait long enough portage will know how to resolve these blockers on its own??

Rich.

Thank you very much, guys.

You unmerge com_err and ss before fetching the packages, reinstall com_err and ss then fetch the new packages (use portage options -fuDN), then unmerge com_err and ss before installing the new packages.

right, the problem is, that I've already done that...and when I do an emerge --search for them, it verifies that they are not installed...

unless you've followed my initial post you will always get this blocking error. The latest portage doesn't fix the blocking error, it just provides you with the stable version of mit-krb5 so you don't have to unmask it.

Follow my initial post except for the "echo" command and it should fix your problem.

forget about mit-krb5 for just this moment and fix your wget error by emerging e2fsprogs.

trouble is that your wget is broken, hence the errors so you'll need to download the files that emerge is trying to download on a different system (i.e. from the livecd and not chrooted) and place then in your chrooted /usr/portage/distfiles.

Something ling the following:

Code:
livecd# cd /mnt/gentoo/usr/portage/distfiles
livecd# wget http://128.61.111.9/pub/gentoo/distfiles/e2fsprogs-1.41.2.tar.gz


then chroot into your /mnt/gentoo as you normally would and try an "emerge e2fsprogs".

It should work if you've downloaded the correct files. If not, check the one its looking for and download it by hand.

Once you've downloaded all the required files the emerge of e2fsprogs should go through and you can then emerge mit-krb5

I also have the nfs-utils package installed, and it's part of the blocking error as well. Is there something different I need to do because of that?
