Attempting to make some ruby gems work, I discovered I needed to install the dev ruby package, which apparently required the dev libc6. When I tried to install it (using the approved squeeze apt-sources), I discovered the latest libc6-dev was out of sync with my current version of libc.
It turns out the version of libc6 I should be using (according to apt) should be libc6 2.11.3-2. I am instead on libc6 2.13-7. At some point a user must have used an upstream source to do something and it grabbed a new libc6.
My question is this: if I want to get back in line with the approved versions for my OS, will I need to uninstall libc6 and all its dependent programs and then reinstall them via apt-get, or is there a better way to do this?
I've also discovered that the latest libc6-dev is uncompatible with the current version of gcc I have (4.4), so going forward isn't an option unless I do that too.
EDIT: The solution we ended up using was to use aptitude to download the .deb files, and then use dpkg to install them.
For example, navigate to /var/cache/apt/archives (just to keep them in the same place apt-get puts them)
execute the following:
aptitude download libc6 -t squeeze
dpkg --force-depends -i <name of package>.deb
This resolved that issue, but obviously it caused another set of dependency issues. Each one can be resolved in the same way.
aptitude download libc-bin -t squeeze
dpkg --force-depends -i <name of package>.deb
Just a note, in my version of apt, -t stable had no effect. You needed to do "aptitude download lib6/stable" instead. – Jeremy Salwen – 2015-02-04T15:08:59.397
just attempted uninstalling glibc and it was not handled gracefully by apt, had to restore from clone. May just have to wait until wheezy is stable and get everything back on the same level, or potentially just upstream the compilers for now and hope for the best. – NateDSaint – 2012-04-02T20:14:48.757
