  • Landed MP 371461, a minor doc improvement
  • Landed MP 371403, which allows secondary VNICs in Oracle Cloud Infrastructure to be configured by cloud-init!
    • This only works on Virtual Machines (not Bare Metal Machines)
    • At the moment, this requires configuration in your image/instance to enable
  • Substantial internal discussions about the future of initramfs network configuration in cloud-init
    • To summarise: nothing needs to change, but we would like to drop the “initramfs” NetworkConfigSource and merge its behaviour into the “fallback” NetworkConfigSource
    • (On an iSCSI-root system, for example, the last-resort, fallback network config should be what the initramfs wrote out, not DHCP-on-first-interface.)
  • Completed my inital dig into Dracut network configuration (my notes are here)
  • Landed MP 371673 with the initial refactoring required to introduce Dracut network configuration parsing
    • This doesn’t change any behaviour, it just moves klibc from being the source of initramfs network configuration to being a source of initramfs network configuration (albeit the only source, for now)
  • Revisited bug 1834875 to confirm that this issue doesn’t lie within cloud-init
  • Code review
  • Landed MP 371350 (see last week for details)
  • Submitted MP 371683 with minor .gitignore updates


  • Dropped building of Python 2 Ubuntu package (python-curtin) in a new upload (19.2-6-g88a1a7ec-0ubuntu1
    • Thanks once again to @raharper for sponsoring the upload
    • This required a minor change upstream (MP 371589) so that the Python 3 tests could be run without the Python 2 tests


  • No substantial UA client work this week


  • Uploaded a new upstream snapshot of simplestreams to eoan (0.1.0-25-gba75825b-0ubuntu1)
    • Thanks to @rbasak for the sponsorship!
  • Spent some time looking at dropping Python 2 from the simplestreams Ubuntu packaging
    • I have branches for this locally, but we have downstream consumers that depend on the Python 2 packages still, so we’ll do it next cycle
  • Investigated and filed a Launchpad bug that was causing our CI and autolander triggers to fail
  • On vacation next week, so won’t be back to work until after International Worker’s Day (North American Edition)

It has been some busy days these last weeks due to Ubuntu Eoan Freeze date. From now on we are concentrating efforts in bringing needed fixes to imported / synced / merged packages that are in Eoan.

Please do test and provide feedback through Launchpad!



  • @paelzer has provided libvirt support for arch-capabilities for Eoan
  • I’m currently working in backporting this support to Disco and Bionic.

LP: #1841066 - ARCH_CAPABILITIES guest capability detection

  • @paelzer bisected QEMU for missing features done in libvirt at LP: #1828495
  • Eoan is good, I’m currently working in backporting support to Disco and Bionic (PPA)

LP: #1841457 - QEMU Eoan GCC9 warnings

  • QEMU source package can’t have .git dir or else -Werror is default.

LP: #1834522 - Bionic QEMU with Bionic Kernel hangs in AMD FX-8350 with cpu-host as pass-through

  • Ubuntu-4.15.x master tree hangs, upstream v4.16 is good (bisecting)

MySQL8 migration

@rbasak is working in MySQL8 transition for some time now, to guarantee migration from Disco→Eoan is smooth. I contributed a bit with some minor issues:



  1. dbconfig option for mysql authentication plugin
  2. mysql can’t handle empty ports in config file
  3. mysql grant fix fort no_auto_create_user
  4. mysql no_auto_create_user fixes for autopkgtest
  5. dbc_authplugin option documentation




cpuinfo and linux
