I'm also getting the same issue, with apt 0.7.23. Sometimes I get: terminate called after throwing an instance of 'std::out_of_range' what(): basic_string::substr
And sometimes I get a segfault, for which dmesg shows something like: [261680.545501] apt-get[29895]: segfault at 19 ip b7fe32fb sp bf8d4ca0 error 4 in libapt-pkg-libc6.9-6.so.4.8.1[b7f6b000+c1000] I did get the following, but not since I reinstalled libc6: [261137.917517] apt-get[24392]: segfault at 9a0b000 ip b7c28b76 sp bfe19878 error 4 in libc-2.9.so[b7bb0000+158000] -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
