Bug#561852: apt: Method http has died unexpectedly (undefined symbol:)

(Seems to be we forget to bump the minor abi while trying hard to not break the major abi) but as the library and the user (method/http) are shipped in the same package the error is still a bit strange, especially as the http method is the most used acquire method and the call to maybe_add_auth is unconditional, so many (read: all) users should have faced this problem... Yes, I agree with that logic and actually very few users reported about behavior like that. So is this somehow reproducible? Since there are so many upgrade paths, I haven't been able to reproduce that starting to upgrade apt from a clean lenny, I tried several combinations with no luck. I wonder if the resetted shared object versioning has something to do with it, e.g: apt 0.7.24 libapt-pkg- libc6.9-6.so.4.8.0 apt = 0.7.24 libapt-pkg- libc6.9-6.so.4.8.1 and then again: apt = 0.7.25 libapt-pkg- libc6.9-6.so.4.8.0 that being said, I don't see many chances for libapt-pkg- libc6.9-6.so.4.8.1 and a previous version libapt-pkg- libc6.9-6.so.4.8.0 (with that symbol missing) to be left in place with a symlink and latest apt-get binary which is trying to resolve the missing symbol. (I reproduced it artificially extracting and putting in place libapt-pkg- libc6.9-6.so.4.8.1 from apt 0.7.24 when apt 0.7.25 was installed, but this is not so realistic as scenario) I would personally prefer to understand why this happen at all before closing the bug to be able to avoid such problems in the future. Yes, I can see your reasons... -- pub 4096R/0E4BD0AB people.fccf.net/danchev/key pgp.mit.edu -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Hi, It turns out that some previous version of apt (= 0.7.24) provide libapt-pkg- libc6.9-6.so.4.8.1 shared object, which according to objdump -T and readelf -s do not provide the missing symbol in question (_Z14maybe_add_authR3URISs). To force dynamic linker to resolve all symbols at program startup instead of when they are first referenced: LD_BIND_NOW=true apt-get update To produce a more verbose debugging about the dynamic linkage: (what object files linker picks up and which symbols are being resolved) on x86: LD_DEBUG=all /lib/ld-linux.so.2 /usr/bin/apt-get update on amd64: LD_DEBUG=all /lib/ld-linux-x86-64.so.2 /usr/bin/apt-get update Since that it a transient breakage, I think we can close that bug safely unless there is a possible upgrade path which could leave the system in a state such that apt-get executable could call maybe_add_auth function without being dynamically linked with the proper shared object providing that symbol (_Z14maybe_add_authR3URISs) as well. P.S. Many thanks to Wil van Lierop (dutchfish) and Ron Lee (ron) for taking part in hunting down that transient breakage on IRC. -- pub 4096R/0E4BD0AB people.fccf.net/danchev/key pgp.mit.edu -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Downgrade to apt-0.7.23.1, apt-get update(not sure if it is needed) and upgrade again solves this problem for me.
