  • I broke the archive a bit when uploading my glibc and base-files merges (once I figure out exactly what happened I’ll try to write it up). Those uploads have been kicked out of -proposed to fix the immediate issue, and I’ll need an AA to look into this bug before I can do a new attempt.
  • As a consequence of my archive breaking mistakes, I hacked a bit on ppa-dev-tools to add support for pocket selection.
  • Started working on fixing the apport test suite for non-amd64 architectures (unfinished due to the aforementioned debacle)
  • Piloted some Patches
  • Some travel planning.

  • proposed-migration: gcc-13 cluster
    • continued work on octave-dicom - I have a concern that the use-after-free seen in octave-dicom testing may be a stdc++ bug. The following test is a more minimal version of the failure:
%!test
%! dicominfo(file_in_loadpath("imdata/simpleImageWithIcon.dcm"));
%!test
%! dicomdict factory ;
  • if pushed we can disable tests on octave-dicom but octave-tisean probably also needs to be addressed
  • supporting work for 24.04.1
