The segmentation fault is likely due to some incompatible libc version being mixed, one being the unpacked version, one being on the filesystem at a different location. > I suspect the problem is somehow related to multi-arch, since it seems > that multiarch is causing one side to deconfigure, breaking that side > and then creating a dependency conflict situation.

We already have one bug similar to yours (#741031) although it concerns the previous upgrade from 2.17 to 2.18. Unfortunately we are not able to understand the bug, as we have not been able to get a status of the system *before* any repair action is taken. Do you by chance still have a system in the broken state? If so, could you please send us the output of: dpkg -l "libc*" ls -l /lib /lib32 /lib64 /lib/i386-linux-gnu/ /lib/x86_64-linux-gnu/ -- Aurelien Jarno GPG: 4096R/1DDD8C9B [email protected] http://www.aurel32.net -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
