Package: dpkg
Version: 1.22.1
Severity: important
File: /usr/bin/dpkg-deb
Dear Maintainer,
3 times in the last month or so I have had apt dist-upgrade stall.
The culprit appears to be dpkg-deb which goes defunct. Once I kill it,
the transaction seems to continue although I have to run "apt-get -f
install" or "dpkg reconfigure -a" to finish it.
It appears to be at the unpack stage where we see the problem.
Another Sid user on social media also has a quite powerful machine (we
both have 32 cores, nvme and 64gb+ ecc ram) and has the same problem, so
maybe its a threading thing? Obviously not a memory/disk issue.
Logs from today's occurrence:

"pkill dpkg-deb" resulted in:
dpkg: error processing archive /tmp/apt-dpkg-install- ilDw1k/081-libgtk-4-doc_4.12.3+ds-2_all.deb (--unpack):
dpkg-deb --fsys-tarfile subprocess was killed by signal (Terminated)
For the rest of the dist-upgrade i keep seeing defunct dpkg-debs:
# ps auxw|grep defunct
root 1331212 0.0 0.0 0 0 pts/2 Z+ 13:14 0:00

defunct
killing them off seems to just spawn a new instance:
# kill -9 1331212
-bash: kill: (1331212) - No such process
# ps auxw|grep defunct

root 1331426 0.0 0.0 6348 2048 pts/3 S+ 13:14 0:00 grep
defunct
At the end of the operation i get:
Errors were encountered while processing:
/tmp/apt-dpkg-install-ilDw1k/081-libgtk-4-doc_4.12.3+ds-2_all.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
W: Operation was interrupted before it could finish
"apt-get -f install" allows the transaction to complete.
I had same problem before with:
/tmp/apt-dpkg-install-PdxOu1/1-texlive-fonts-
extra_2023.20231007-1_all.deb and another package I can't quite remember
before
that.
-- Package-specific info:
This system uses merged-usr-via-aliased-dirs, going behind dpkg's
back, breaking its core assumptions. This can cause silent file
overwrites and disappearances, and its general tools misbehavior.
