The fix, with a test case, is already in upstream.[2]


So let's reassign to procps exclusively. Doing so with this message.

What is happening here is that pslist is running in effect "ps axco
pid,ppid,command | grep "
It's a bit odd, asking for command and using the c option to change that to
comm, far better to use comm directly.
However, asking for something in a strange way should still work.

Ignoring the c means the program is not called "test-pslist" but
"/usr/bin/perl /test-pslist"

In any case, ps is ignoring the c option for the output of command. The
change happened at [1] and the fix is a two-liner in ps/output.c
The fix, with a test case, is already in upstream.[2]

Bug#1026326: procps breaks pslist autopkgtest

[Paul Gevers]

Source: procps, pslist
Control: found -1 procps/2:4.0.2-2
Control: found -1 pslist/1.4.0-4

Dear maintainer(s),

With a recent upload of procps the autopkgtest of pslist fails in 
testing when that autopkgtest is run with the binary packages of procps 
from unstable. It passes when run with only packages from testing. In 
tabular form:


   passfail
procps from testing2:4.0.2-2
pslist from testing1.4.0-4
all others from testingfrom testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of procps to testing 
[1]. Due to the nature of this issue, I filed this bug report against 
both packages. Can you please investigate the situation and reassign the 
bug to the right package?
