View Full Version : [all variants] Internal Error, Could not perform immediate configuration (2) on libc6

March 16th, 2009, 07:48 PM
last week i came across this error, like hitting a wall with mach 10, while performing a dist-upgrade from gutsy to intrepid.

after serious investigations i learned, that this was caused by apt due to cyclic dependencies. or what ever this is called... :)
I recognized it would be useful to post the information on ubuntuforums!

the one and only solution i found, is following this:

sudo apt-get remove libc6-dev
sudo apt-get -d install libc6
cd /var/cache/apt/archives
sudo dpkg --force-depends --install libc6_2.8~20080505-0ubuntu7_i386.deb findutils_4.4.0-2ubuntu3_i386.deb
sudo apt-get -f install
sudo apt-get dist-upgrade

(adapt .deb packages to your needs)
i suggest not to apply,
sudo apt-get cleanas suggested on
because this wipes your /var/cache/apt/archives, and on slow connections you seriously won't! that after collecting ~700MB packages.

I don't think you can jump or skip a release. You should have gone from gutsy -> hardy -> intrepid.

dist-upgrade is working atm... i am eager to experience the result.
luckily, this box is not vital, so why stop an experiment? :)

i am going to publish any error reports here. if no problem arises, then all went ok.

after a third ubuntuuser confirms the solution, i view above code as a working way to untie the interdependencies between libc6 and findutils.

Following upgrade instructions at


I got this error while running

sudo apt-get install update-manager-core

The first apt-get install command failed for me with the same error, but I went ahead to installing the debian package (in other words, started with line 3) and got update-manager-core installed.
