[hardy] login failed on 2.6.24-12 generic

[fragro]

the gdm logon doesnt start. the console logon crashes with the folowing lines:

...
malloc: ../bash/subst.c:3472: asertion botched
free: called with unallocated block argument
Aborting...complete: usage: complete [-abcdefgjksuv] [-pr] [-o option] [-A action] ...

malloc: ../bash/subst.c:3472: asertion botched
free: called with unallocated block argument
Aborting...
malloc: ../bash/subst.c:3472: asertion botched
free: called with unallocated block argument
Aborting...init: tty6 main process ended, respawning

after some time the boot continues, goes to graphic mode and the screen is blank and starts to enlighten (from top of screen from green to whole screen changing to white)

When i try to startup in recovery mode this lines is shown me and then nothing:

malloc: unkown:0: assertion botched
free: called with unallocated block argument
last command: startx
Aborting...Aborted
init: rcS-sulogin main process (4632) terminated with status 134

can you help me how i can fix this or logon to get latest updates/fixes?

I had something similar due to the glibc update yesterday that was broken.

Boot into your Ubuntu LiveCD.
Mount the partition. (you can do this from console, or by GNOME in "Places" -> Computer -> Filesystem.

Type:
cp --parents `dpkg -L libc6-i686 | xargs` /path/to/mounted/disk/
cp --parents `dpkg -L libc6 | xargs` /path/to/mounted/disk/

thanks Fred, that solution worked for me with an Edgy Live CD

[Colin Watson (cjwatson)]

I strongly recommend not using an Edgy live CD for this purpose; other programs almost certainly require features of the newer C library in Hardy and will fail to work correctly or at all. If you do this and manage to get the system to boot afterwards, you should upgrade to libc6 2.7-5ubuntu2 or 2.7-9ubuntu2 (NOT 2.7-9ubuntu1) from Hardy as soon as possible.
