I found out that the files /var/cache/apt/pkgcache.bin and /var/cache/apt/srcpkgcache.bin caused the problem.
I renamed them to *.bin2. This appearently solved the problem. Attached is a tar.gz including the two broken .bin-files that causes apt-get to segfault and an strace of apt-get update when it seqfaults. ** Attachment added: "causes-crash.tar.gz" http://launchpadlibrarian.net/31317533/causes-crash.tar.gz -- apt-get crashes on apt-get update https://bugs.launchpad.net/bugs/424182 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
