Package: autopkgtest Version: 5.4.1 Severity: grave Justification: renders package unusable
Dear autopkgtest Maintainers, In various situations autopkgtest calls /bin/su with an empty string for the username. The old su (from login) ignored this, but newer su versions (from util-linux 2.32-0.2) do not accept this, and abort. Personally I think autopkgtest got lucky that this worked before, but this probably was not a valid thing to do. One of the affected lines: https://sources.debian.org/src/autopkgtest/5.4.1/lib/adt_testbed.py/#L1096 Example output from autopkgtest: autopkgtest [15:52:36]: test supported-algos: [----------------------- su: user does not exist autopkgtest [15:52:36]: test supported-algos: -----------------------] Unexpected error: Traceback (most recent call last): File "/usr/share/autopkgtest/lib/VirtSubproc.py", line 717, in mainloop command() File "/usr/share/autopkgtest/lib/VirtSubproc.py", line 646, in command r = f(c, ce) File "/usr/share/autopkgtest/lib/VirtSubproc.py", line 584, in cmd_copyup copyupdown(c, ce, True) File "/usr/share/autopkgtest/lib/VirtSubproc.py", line 469, in copyupdown copyupdown_internal(ce[0], c[1:], upp) File "/usr/share/autopkgtest/lib/VirtSubproc.py", line 494, in copyupdown_internal copyup_shareddir(sd[0], sd[1], dirsp, downtmp_host) File "/usr/share/autopkgtest/lib/VirtSubproc.py", line 408, in copyup_shareddir shutil.copy(tb, host) File "/usr/lib/python3.6/shutil.py", line 241, in copy copyfile(src, dst, follow_symlinks=follow_symlinks) File "/usr/lib/python3.6/shutil.py", line 120, in copyfile with open(src, 'rb') as fsrc: FileNotFoundError: [Errno 2] No such file or directory: '/tmp/autopkgtest.zwqy11/supported-algos-stdout' autopkgtest [15:52:36]: ERROR: testbed failure: cannot send to testbed: [Errno 32] Broken pipe autopkgtest [15:52:36]: Binaries: resetting testbed apt configuration Note that tests that say "Restrictions: needs-root" do not appear to hit those code paths. I might try to come up with a patch if no one beats me to it. Chris
