  • subiquity
    • Matching stable release of Subiquity to what is found in Jammy.
    • LP: #1969822 - Investigate user report of formatting troubles with Jammy. This is a confusing bit of UX about what the “Format” option does on a Disk.
    • LP: #1969970 - Review the bug, run netboot test over PXE, works for me, issue confirmed by submitter to be an invalid ISO.
    • LP: #1950914 - Issue with virt not booting Jammy. Reproduce, not Subiquity specific, provide workaround (don’t use video=vmvga).
    • LP: #1970116 - Confirm issue with reuse of md device. Review work by @mwhudson on this
    • LP: #1970595 - Triage issue about netboot downloading the ISO too many times. Merge with LP: #1937319
    • Review: PR: 1252, PR: 1272, PR: 1280, PR: 1282, PR: 1285
  • curtin
    • MP: 419640 - fix resize case where a format action is not specified. A format action is not required if nothing about the format action is changing.
    • MP: 420511 - fix bug with resize and partition wiping, add matching integration test
    • MP: 420513 - resize of NTFS
    • MP: 420564 - reenable some swap-related tests
    • (no MP yet) - working on resize of a Windows 10 install - curtin is not handling the type value of partitions correctly, and there may be more problems lurking after that.

  • Update RISC-V roadmap

  • flash-kernel (LP: # 1970063)
    My patch to add the PolarFire Icicle board has been accepted upstream. Debian has provided a new release. We should package it.

    I created a merge request to add Ubuntu kinetic to the syntax highlighter (https://salsa.debian.org/vim-team/vim-debian/-/merge_requests/7)

I am on +1 this week:

  • khmer (LP: #1970232)
    Package khmer fails to build with Python 3.10. Upstream https://github.com/dib-lab/khmer/ has not been maintained since 2019. We should drop the package.
  • oss4 (LP: #1969145)
    I fixed the autopkgtest regression on amd64. But there are still issues on other architectures.
  • dnsdbq (LP: #1970551)
    I fixed the build failure. Needs sponsoring.
  • doodle (LP: #1970410)
    I fixed the build failure. Needs sponsoring.

  • Nezha kernel: rebased on top of unstable 5.17 functional
  • u-boot-nezha: update to 2022.04
  • u-boot-nezha: added support for kernel dtb fixup in order to be able to detect RAM size at runtime (which makes the image for Nezha almost usable on the LicheeRV board with 512MB of DRAM)
  • initrd large size investigation: RISC-V modules are 20% bigger than x86 and includes lots of gpu/drm drivers/firmware which explain why it is 320MB compared to x86’s 200MB => This large size prevents the LicheeRV board to use the nezha image.
  • VisionFive kernel: Investigation around the audio output that does not work (it works for Fedora)
