After the my latest emerge --sync I got:

This is a coreutils package for plain i686:
http://demandiseineseite.gmxhome.de/bin/coreutils-6.9-r1.tbz2
Just unpacking it and exporting the ./bin folder to your PATH should enable you to emerge coreutils. There should be several threads around for resolving cyclic blocker bugs, also have a look at the Gentoo Handbook.

EDIT: If you have ABI problems ("*.so.x.y not found" or suchlike) let me know and I'll compile a static version.

EDIT2: Just discovered that coreutils-6.10 and greater don't need mktemp any more, so just unmerge that.

There is no coreutils-binary or anything like it. A LiveCD would definitely be the way to go now.

As also commands like cp, chmod, echo, cat etc. are missing on your brick now, I doubt you could install a binary package anyway.

Maybe try to copy over the most important command files from a live CD or another Linux box, pray that they'll work and try until you can re-emerge coreutils again.

Okay. It'll have to sit there lobotomized until I get home then

Sorry, Voltago... I didn't see your reply right away. Your tarball works perfectly

I'm re-emerging coreutils right now!

Thank you *so* very much for making that available!

I'm glad I found this thread. I had tried to look back at the log of files uninstalled when I had foolishly allowed coreutils to be unmerged. I created a file from that and tarred up all those files on another system. Guess that's not a very complete method. I had a working system (ls and cp and all were back) but it was *not* enough to get emerge to work.

This tarball saved my bacon.

Thanks!

stupid me did the same thing.
Thanks a lot for the tarball, my system is working again

Saved my day as well :-)

Just as a reminder, exporting path is:

I unmerged coreutils as well, and the computer stops during boot up. I am now using a liveCD (Ubuntu! - had it lying around), and I will unpack the files to the correct place in the hope I can get it going again. I must admit, as soon as I saw the last entry in the log file, I realised what I had done:

paulj · Guru Joined: 30 Sep 2004 Posts: 513 Location: Wales, UK

Yep - that worked. I had to create a symbolic link from /bin/env to /usr/bin/env, in order to use portage scripts without error messages.

As an improvement suggestion, maybe Portage should have a list of files which will really give you a problem if unmerged, and ask for your confirmation before allowing you to do something stupid. Also, the blocking error message could have been solved by only unmerging mktemp - maybe there could be an information message to that effect when trying to emerge coreutils-6.10?

Thanks again for the tip and tarfile

Rgds.,
Paul

I removed it too.

I used it as an excuse to re-partition my disks and add some more new disks.

I have the same problem after unmerging coreutils. I do not understand how to export PATH to have the tool command available needed to remerge coreutils. I have unpacked old coreutils but I need also some comands like "rm" to have possibilty to reemerge coreutils. After: chrooting && env-update && source /etc/profile; the commands are not available.

It would be very good with a version of the coreutils files that only requires wget, no tar or bzip.

Old version I still had on my comp is coreutils-6.9-r1.bz2. I am trying to chroot from ubuntu live-cd to reemerge old version first.
I am trying to do this by commands:
mkdir /mnt/gentoo
mount /dev/hda3 /mnt/gentoo
swapon /dev/hda2
mount /dev/hda1 /mnt/gentoo/boot
mount -t proc proc /mnt/gentoo/proc
chroot /mnt/gentoo /bin/bash
etc-update && source /etc/profile
emerge =sys-app/coreutils-6.9-r1

and answer I obtained is (among others):

/usr/lib/portage/bin/ebuilds.sh line 693: rm: command not found

The command "emerge =sys-app/coreutils-6.9-r1 > trace" gives back the following trace file:

I didn't try to emerge the new version directly. First of all, I mounted the drive from an Ubuntu live CD. I then uncompressed the files in the bin sub-directory of the tarfile mentioned above into the /usr/bin directory on the Gentoo installation. This allowed me to boot, but I had a problem with the lack of /usr/bin/env. Without this file, many of the portage scripts don't seem to run (shebang reference is missing?). Normally this is a symbolic link to /bin/env, so a quick

I extracted the coreutils package provided by Voltago ( Thank you

)
Then exported the PATH variable and emergeed coreutils, but got a "rm command not found" message.
So I began making symbolic links of the missing commands in the /bin directory and /usr/bin directory
to the binaries available in the extracted directory. As a result the "command not found" messages are gone
but now there's a new error that I can't put my hands on.

Here's the output of "emerge coreutils"

Hello,

I too did the same bone head thing and after uncompressing the fiels and exporting the paths, when I would emerge rm/mkdir/env and others were not found.

Out of frustration I just copied the uncompressed file to /bin and /usr/bin (did not overwrite any existing) and that seemed to work.

Thanks,
Bill

Bill,

Thank you so much!

Hi Guys,

Unfortunatelly I have also unmerged coreutils, now having the same problem. I got a bit panic, gentoo was my only system at home computer, now I am writing from my collegue's one asking You for a kind of tutorial how to restore my system, since I am not sure I am doing the things mentioned by You in the correct order and generally how it should be:(
What I do is:
1. Boot from Gentoo Linux 2007 minimal cd, mount my swap, root and proc partition
2. Perform /mnt/hda1(my root partition) /mnt/gentoo, chroot /mnt/gentoo /bin/bash, env-update && source /etc/profile
3. cd /bin
4.wget http://demandiseineseite.gmxhome.de/bin/coreutils-6.9-r1.tbz2
5. tar xvjpf coreutils.... (I do the same 3,4,5 for /usr/bin )
6.I perform: export PATH="${PATH}:/home/piotrek/temp/usr/bin" (but I don't know why this one:( , that is why I also do te same for /bin and /usr/bin)
7. When I try: ln -s /bin/env /usr/bin/env I get a message that there is no such command as 'ln'

what should I do??

Could You please put this instructions for me in such kind of order since had difficulties with reading all Your suggestions and unfortunately I didn't managed to perform them well. I really want to get back my gentoo for monday morning presentation:(

Stolar - too complicated!

Use suitable liveCD to boot the system, then mount the partition with your /usr directory.
Uncompress the contents of the tarfile with coreutils (see Voltago's post above) into /bin and /usr/bin, without replacing anything that is already there. Normally the /usr/bin softlinks to /bin, but copying the files twice is easier than recreating all the links .
Reboot the computer. It should now boot normally.
unmerge mktemp
emerge -avuDN world (or whatever command combination you normally use).

The new coreutils should now install, and overwrite the previous coreutils files in /bin and /usr/bin. No need to chroot or run emerge from within a chroot environment.

Good luck! :wink:

Paulj thank You for reply but unfortunatelly I still have the same error while booting my gentoo.

I booted from minimal CD, mounted my / partition, then enetered /bin and /usr/bin respectively unpacking there the stuff provided by Voltago and after reboot I get the same errors...The last on which the machine changs is: 'Skipping /var/run/utmp initialization (ro root?)'. Could have I done something wrong while doing it the way I had presented in my previous post? I wasn't asked to overwrite anything. I only did: wget http://... and then tar xvjpf coreutils... and everything went fine up to that moment but after reboot I still have the same problem:(

...Now I have at least manually removed mktemp ebuild and I have no packets blocking my coreutils emerge,but when I try to emerge it I get the same error as TreeLearner with the 'setup'. After 'ln -s /bin/env /usr/bin/env' command the system tells me that such symbolic link already exist. How to emerge those coreutils??
