StarFive VisionFive 2

  • As the some versions of the vendor U-Boot have issues with booting our images I have uploaded a u-boot-starfive package to ppa:ubuntu-risc-v-team/release based on the current upstream U-Boot next branch plus a few patches. In the 24.04 release we can u-boot-starfive out of the u-boot source package.

OpenSBI

  • The current upstream OpenSBI has several issues detectable via Coverity. I have send a bunch of patches upstream to correct these.

llvm-toolchain-17

  • llvm-toolchain-17 riscv64 build suffer from a very high memory consumption. On behalf of @doko I have been building the package locally and provided memory consumption logs.

Greenhouse

  • I have reviewed a bunch of submissions.

ubuntu-image

Proposed a fix for the following issues:

  • PR #146 - ubuntu-image classic always passes --vcs=auto to germinate even when told not to
  • PR #144 - Pathname for manual customization not relative to image definition file
  • PR #143 - # The ‘fstab’ of ‘customization’ destroy original fstab content

These PR are waiting for a review.

Merged a PR from the snapd team regarding volume/partition size

Distro

  • FTBFS
    • setuptools - LP: #2037205 - Found a fix but I am still working to understand why this is still failing to build in LP.

  • livecd-rootfs
    • MP: #452012 (LP: #2036966) - budgie: fix sources.list to have the normal template, particularly to pick up multiverse. Also file LP: #2037327 about improving the API of this code.
    • LP: #2028862 - finalize livecd-rootfs testing of this SRU, migration to jammy release pocket accepted, resulting ISO looks good.
  • seeds
    • MP: #452156 (LP: #2037425) - Drop zfs-initramfs and zfsutils-linux from the server seed.
    • MP: #452158 - On the basis that zfs-initramfs is dead weight to server-live, then it would also be dead weight to live, so open this MP also.
  • subiquity
    • PR: #1804 (LP: #2034715) - wait longer on snapd for the TMPFDE finish_install sequence
    • PR: #1806 (LP: #2009141) - reduce the time spent on udev event processing when deciding to probe storage devices.
    • PR: #1810 - stable branch merge
  • Investigating LP: #2037569 - there appears to be a loop between udev rules and how udisks2 is working on s390x. Not installer specific as can be seen in the installed system. I expect that this will need a change to udisks2 but don’t know what that is yet.
  • curtin
    • MP: #452185 - continue vmtest cleanup. cloud-init SRU testing uses part of the curtin vmtest suite, and this fell out of date, so fix that.

  • 24.04 prep

Netplan

  • PR reviews from community PR#410 PR#411
  • Meeting with UX to talk about the netplan diff interface
  • Investigation of why some autopkgtests started to fail in Jammy. After trying different versions of systemd and kernel, I’ve found that networkd started to fail to create ip6_gre interfaces when the kernel 5.15.0-83.92 was added. Downgrading to 5.15.0-82.91 or using the HWE kernel (6.2) makes it work again. The diff between 5.15.0-82.91 and 5.15.0-83.92 shows some changes in the ip6_gre and netlink drivers but I’m not sure why it broke. We still need to decide if we can hint the test as it’s blocking a proposed migration LP#2025519

subiquity

  • addressed crash when the original storage configuration is queried too early.
  • fixed failure when listing available OEM meta-packages in semi-automated desktop installs (unexpected order of events)
  • investigating an endless loop of udev events causing various issues during installs. It seems easy to reproduce on s390x but is not limited to.
  • working on making desktop installations fallback to offline installs if the mirror testing does not pass. This involves skipping operations that require access to the network.
