I recently <successfully> upgraded from RHRH8.0 to 9.0 (kernel 2.4.20-8).
Tonight I decided to run up2date on my machines. One is fine (now at 2.4.20-9), but my laptop had an issue.
For some reason, the up2date process croaked. I came back to find the bootloader menu

Now I have the following error message appearing whenever I issue a command. For example if I run rpm I get:
rpm: relocation error: /lib/i686/libpthread.so.0: symbol _h_errno, version GLIBC_2.0 not defined in file libc.so.6 with link time reference.

I can't update the GLIBC files, because rpm won't run. Up2date won't run from the command line. Xwindows won't run. Aaaaaack !

Any help would be greatly appreciated.

You have lost something pretty basic. My guess is that it is one of the shared libraries. You may have to do a complete reinstall.

But in the spirit of why not mess with it since the worst that can happen is a complete reinstall I would start by looking at /etc/ld.so.config. Restore every library listed in ld.so.config from backup and then run ldconfig.

you'll find some answers at these two threads:

PS. I didn't do it yet, but I think the solution is to boot into rescue mode from the installation cdrom or your rescue floppy, chroot to the root directory of your damaged linux system, then do rpm -e on glibc followed by rpm -I of the new rpm's. Seems like the problem arose because the old glibc was not properly removed during the upgrade with up2date.

I had the same problem, so I'll give that fix a try and post the results here. Just have to find the time to do a full system backup first...

Thanks!

Did it, same result. I'm not sure if a "rpm --force -e glibc" would do better, but I'm too much of a chicken for that right now...

Looks like a manual compile/install of glibc is in order...

--force parameter only works with -U or -i, following my little data.

ps. and take a look at bugzilla:

https://bugzilla.redhat.com/bugzilla...g.cgi?id=88456

Good news, I did the following:

rpm -Uvh --force glibc-2.3.2-27.9.i386.rpm glibc-common-2.3.2-27.9.i386.rpm
ldconfig

And it worked!

I apparently have to recompile Apache, but everything else looks like it's in good order...
