[Bug 508083] Re: cron crashed with SIGSEGV in __pthread_initialize_minimal_internal()

[Steve Langasek]

However, note that the oneiric->precise upgrade log also shows this
output from the libc6 preinst:

Preparing to replace libc6 2.13-20ubuntu5 (using .../libc6_2.15-0ubuntu2_amd64.deb) ...
locale: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.15' not found (required by locale)
locale: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.14' not found (required by locale)
Checking for services that may need to be restarted...
Checking init scripts...
runlevel: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.14' not found (required by /lib/x86_64-linux-gnu/libnih.so.1)
runlevel: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.15' not found (required by /lib/x86_64-linux-gnu/libnih.so.1)
Unpacking replacement libc6 ...

libnih1 is being unpacked before the libc6 that it depends on, making
the runlevel command unusable (and, btw, making the system unbootable
during this window!).  We'll need to fix that as well, otherwise we
can't reliably detect that cron should be stopped.

  I installed karmic in Virtualbox. I updated it. I upgraded to Lucid on
