the issue can be worked around by removing/renaming the srcpkgcache.bin and pkgcache.bin files, located in /var/cache/apt.
of possible interest is bug 61708. Before discovering the workaround, I manually downgraded all feisty packages I thought would affect apt. The segfault still existed. Also, I believe the .bin files were supposed to be regenerated when they became corrupted - maybe the bug is in the corruption-detection code. -- segfault on apt-get upgrade https://launchpad.net/bugs/70005 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
