Hi everyone, below you will find the updates from the Desktop team from the last week.

If you’re interested in discussing a topic please start a thread in the Desktop area of the Community Hub (this site).
We also have our weekly meeting on IRC. We meet on Tuesday at 13:30 UTC in #ubuntu-desktop on Freenode. There will be an “Any Other Business” section at the end where you are welcome to raise topics. These topics might be discussed during the meeting, or afterwards depending on the time, depth of conversation, topic and so on.

Last week’s notes are here: Monday 10th June 2019

  • Updated GLib and SRUed it
  • Mailed the Debian GNOME team about moving our packaging branches over to salsa - this was a change we discussed some time ago and I was slow in getting round to. cc @jbicha

  • cups-filters: Continued on finding a fix for the new cups-browsed to work with legacy CUPS servers (IPP 1.x). See this upstream issue report.
  • network-manager: Got some hopefully useful info on the Bionic regression in bug 1829566. Checked the log, asked for further info and got it but not checked again yet.
  • network-manager: Looked through the code of the autopkg test to get a clue what is wrong with it. I was able to reproduce it.
  • Google summer of Code 2019: One student (the one to improve pdftoraster in cups-filters to not use unstable APIs) finished his work 2.5 (of 3) months before the end of GSoC. Assigned to him a second project (make Common Print Dialog Backends work with GTK print dialog) and found a mentor for mentoring him on that.
  • Linux Plumbers Conference 2019 in Lisbon: The OpenPrinting microconference got publicly listed.
