LIBC PANIC!! - LIBC fork: when 'yum install docbook*'

[Andib]

I thought this LIBC Panics are solved but...

I don't think the following problems are related to another ticket but sorry in case I overlooked matching ticket.

Here comes a lot of information I don't understand. But clearly something went wrong.

Komplett!

For the casual rpm user like me it's not clear if the whole thing is installed correctly as another 'yum install docbook*' says, or something went wrong - 'Fehlgeschlagen: sgml-common.....'. Of course I can reinstall sgml-common. But is this necessary?

The message 'python-libs-2.7.6-14.oc00.i686 ist ein Duplikat von python-libs-2.7.6-14.oc00.i686' does not sound very informative to me too.

[Silvan Scherrer]

unfortunately this is one of the issues we face from time to time. But we can't reproduce it. And "Fehlgeschlagen" means it's not completely installed, as some scriplets are not run. This might or might not hurt. All depends on the scriplet.

[Silvan Scherrer]

please try to issue the command not on a root dir. I wonder if it makes a difference.
As I had this issue today as well when doing it on a root dir. If going to some subdir it worked.
It could give us some hints, when others see the same.

[Andib]

Confirmed.

'p:\yum reinstall docbook*' reproducible gives some LIBC PANIC!!
'p:\etc\yum reinstall docbook*' - no LIBC PANIC anymore.

I'm working on updating the bootstrap (last build was 2016-06-10). Upon updating python, I'm seeing the same thing (when running yum from root), but in (or before) a postin scriptlet (same panic, though).

I can confirm that reinstalling while changed to \etc reinstalls properly, and other than warning of a failure removing a transaction file, the reinstallation succeeds (no panic).
