Package: apt
Version: 1.8.0~alpha3
Severity: normal
For the past few weeks, I haven’t been able to update my Debian system. I
finally took some time to look into what’s going wrong.
The symptom is that “apt update” just hung forever after fetching all files from
my configured mirrors.
A closer look revealed 100% CPU usage of 1 core in the
/usr/lib/apt/methods/store process, which was writing to files in
/var/lib/apt/lists/partial.
Attaching gdb revealed that store was spending its time in a zstd function:
#0 0x00007f376cc0bf78 in ?? () from /usr/lib/x86_64-linux-gnu/libzstd.so.1
#1 0x00007f376cbcc275 in ?? () from /usr/lib/x86_64-linux-gnu/libzstd.so.1
#2 0x00007f376cbcdedf in ?? () from /usr/lib/x86_64-linux-gnu/libzstd.so.1

Sure enough, raising the cost of the zstd compression in my apt config fixed the
issue:
% cat /etc/apt/apt.conf.d/99disable-zstd
APT::Compressor::zstd::Cost "999";
I have a few remarks:
1. Why are the lists re-compressed at all?
(Also note that I set Acquire::GzipIndexes "yes", so I have already signaled
that I would prefer to accept the lists as they are.)
2. Why is store only using 1 of 16 CPU cores for compression?
3. Should we disable zstd for the time being, given that it turns a 1-minute apt
update into a many-minute apt update, to the point where I had assumed it was
hanging?
Thanks,
