[Bug 506342] Re: apt-get crashed with SIGSEGV in __fprintf_chk()
I mount my /var/log on a ramfs (since I run off a 4G thumbdrive), and worked around the problem by creating any necessary directories in rc.local. I've also created in rc.local a link from /var/cache/apt to a /tmp/debs (with /tmp mounted as tmpfs) and create the /archives/partial directory (path). Postgres also needs a directory. This setup puts some of the most active write locations into ram, instead of (slow) flash, which has a limited lifespan. -- apt-get crashed with SIGSEGV in __fprintf_chk() https://bugs.launchpad.net/bugs/506342 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
[Bug 506342] Re: apt-get crashed with SIGSEGV in __fprintf_chk()
Here is a patch to fix the problem. I've tested it with latest apt bzr branch. After changes, apt-get logs the following lines instead of giving a segmentation fault.

[Bug 506342] Re: apt-get crashed with SIGSEGV in __fprintf_chk()
I think crash happens because code snippet below (from apt-
pkg/deb/dpkgpm.cc:656) does not check if history_out is valid.
string history_name = flCombine(_config-FindDir(Dir::Log),
_config-Find(Dir::Log::History));
if (!history_name.empty())
{
FILE *history_out = fopen(history_name.c_str(),a);
fprintf(history_out, End-Date: %s\n, timestr);
fclose(history_out);
}
Problem gets triggered for me because my Dir::Log directory does not
exists, due to the fact I've mounted my /var/log to a tmpfs.
$apt-config dump
...
Dir::Log var/log/apt;
Dir::Log::Terminal term.log;
Dir::Log::History history.log;
...
I can confirm issue has disappeared after I've created directory
manually.
